WARNING
•
• Centrally locate the furnace with respect to the
proposed or existing air distribution system.
• Ensure the temperature of the return air entering the
furnace is between 55°F and 100°F when the furnace is
heating.
• Provide provisions for venting combustion products
outdoors through a proper venting system. Special
consideration should be given to vent/ue pipe routing
and combustion air intake pipe when applicable.
Refer to Vent/Flue Pipe and Combustion Air Pipe
-Termination Locations for appropriate termination
locations and to determine if the piping system from
furnace to termination can be accomplished within
the guidelines given. NOTE: The length of ue and/
or combustion air piping can be a limiting factor in the
location of the furnace.
• Locate the furnace so condensate ows downwards
to the drain. Do not locate the furnace or its
condensate drainage system in any area subject to
below freezing temperatures without proper freeze
protection.
• Ensure adequate combustion air is available for the
furnace. Improper or insucient combustion air
can expose building occupants to gas combustion
products that could include carbon monoxide. Refer
to Combustion and Ventilation Air Requirements.
• Set the furnace on a level oor to enable proper
condensate drainage. If the oor becomes wet or
damp at times, place the furnace above the oor on
a concrete base sized approximately 1-1/2” larger
than the base of the furnace. Refer to the Horizontal
Applications and Considerations for leveling of
horizontal furnaces.
• Ensure upow or horizontal furnaces are not installed
directly on carpeting, or any other combustible
material. The only combustible material allowed is
wood.
• A special accessory sub-base must be used for
upright counterow unit installations over any
combustible material (including wood). Refer to sub-
base instructions for installation details. (NOTE: A
sub-base will not be required if an air conditioning coil
is located beneath the furnace between the supply air
opening and the combustible oor.
• Exposure to contaminated combustion air will result in
safety and performance-related problems. Do not install
the furnace where the combustion air is exposed to the
following substances:
permanent wave solutions
chlorinated waxes or cleaners
chlorine-based
carbon tetrachloride
water softening chemicals
swimming pool chemicals
deicing salts or chemicals
halogen type refrigerants
printing inks
cleaning solutions (such as perchloroethylene)
paint removers
varnishes
hydrochloric acid
cements and glues
antistatic fabric softeners for clothes dryers
masonry acid washing materials
• Enclose a non-direct vent furnace if it is installed near
an area frequently contaminated by any of the above
substances. This protects the non-direct vent furnace
from airborne contaminants. To ensure that the
enclosed non-direct vent furnace has an adequate
supply of combustion air, provide air from a nearby
uncontaminated room or from outdoors. Refer to
the Combustion and Ventilation Air Requirements for
details.
• If the furnace is used in connection with a cooling coil
unit, install the furnace upstream or in parallel with the
cooling coil unit. Premature heat exchanger failure will
result if the cooling unit is placed ahead of the furnace.
• For vertical (upow or downow) applications, the
minimum cooling coil width shall not be less than
furnace width minus 1”. Additionally, a coil installed
above an upow furnace or under a counterow
furnace may be the same width as the furnace or may
be one size larger than the furnace. Example: a “C”
width coil may be installed with a “B” width furnace.
• For upow applications, the front of the coil and
furnace must face the same direction.
• If the furnace is installed in a residential garage,
position the furnace so that the burners and ignition
source are located not less than 18 inches (457 mm)
above the oor. Protect the furnace from physical
damage by vehicles.
• If the furnace is installed horizontally, ensure the
access doors are not on the “up/top” or “down/
bottom” side of the furnace.
9
• Do not connect this furnace to a chimney ue that
serves a separate appliance designed to burn solid
fuel.
• On Counterow Installations, the air conditioning coil
must be downstream on the supply (positive) side of
the furnace heat exchanger.
• Counterow Installation over a noncombustible oor.
Before setting the furnace over the plenum opening,
ensure the surface around the opening is smooth
and level. A tight seal should be made between the
furnace base and oor by using a silicone rubber
caulking compound or cement grout.
• Counterow Installation over a combustible oor.
If installation over a combustible oor becomes
necessary, use an accessory sub-base (see
Specication Sheet applicable for your model for
details.) A special accessory sub-base must be used
for upright counterow unit installations over any
combustible material including wood. Refer to sub-
base instructions for installation details. Follow the
instructions with the sub-base for proper installation.
Do not install the furnace directly on carpeting, tile, or
other combustible material other than wood ooring.
(NOTE: The sub-base will not be required if an air
conditioning coil is installed between the supply air
opening on the furnace and the oor.)

CLEARANCES AND ACCESSIBILITY
NOTES:
• For servicing or cleaning, a 24” front clearance is
required.
• Unit connections (electrical, ue and drain) may
necessitate greater clearances than the minimum
clearances listed above.
• Clearance in accordance with local installation
codes, the requirements of the gas supplier and the
manufacturer’s installation instructions.
• Dégaugement conforme aux codes d’installation
locaux, aux exigences du fournisseur de gaz et aux
instructions d’installation du fabricant.
• In all cases, accessibility clearance must take
precedence over clearances from the enclosure
where accessibility clearances are greater.
Installations must adhere to the clearances to combustible
materials to which this furnace has been design certied.
The minimum clearance information for this furnace is
provided on the unit’s clearance label. These clearances
must be permanently maintained. Clearances must
also accommodate an installation’s gas, electrical, and
drain trap and drain line connections. If the alternate
combustion air intake or vent/ue connections are used
additional clearance must be provided to accommodate
these connections. Refer to Vent/Flue Pipe and
Combustion Air Pipe for details.
NOTE: In addition to the required clearances to
combustible materials, a minimum of 24 inches
service clearance must be available in front of the unit.
A furnace installed in a conned space (i.e., a closet or utility
room) must have two ventilation openings with a total minimum
free area of 0.25 square inches per 1,000 BTU/hr of furnace
input rating. Refer to Specication Sheet applicable to your
model for minimum clearances to combustible surfaces. One
of the ventilation openings must be within 12 inches of the top;
the other opening must be within 12 inches of the bottom of
the conned space. In a typical construction, the clearance
between the door and door frame is usually adequate to
satisfy this ventilation requirement.
Existing Furnace Removal
NOTE: When an existing furnace is removed from
a venting system serving other appliances, the
venting system may be too large to properly vent the
remaining attached appliances.
The following vent testing procedure is repro duced from
the American National Standard/National Standard
of Canada for Gas-Fired Central Furnaces ANSI Z21.47,
CSA-2.3 latest edition Section 1.23.1.

CARBON MONOXIDE POISONING HAZARD
Failure to follow the steps outlined below for each
appliance connected to the venting system being placed
into operation could result in carbon monoxide poisoning
or death.
The following steps shall be followed with each appliance
connected to the venting system placed in operation,
while any other appliances connected to the venting
system are not in operation:
1. Seal any unused openings in the venting system.
2. Inspect the venting system for proper size and
horizontal pitch, as required by the National Fuel Gas
Code, ANSI Z223.1 or the Natural Gas and Propane
Installation Code, CSA B149.1-15 and these
instructions. Determine that there is no blockage or
restriction, leakage, corrosion and other deficiencies
which could cause an unsafe condition.
3. As far as practical, close all building doors and
windows and all doors between the space in which
the appliance(s) connected to the venting system are
located and other spaces of the building.
4. Close fireplace dampers.
5. Turn on clothes dryers and any appliance not
connected to the venting system. Turn on any
exhaust fans, such as range hoods and bathroom
exhausts, so they shall operate at maximum speed.
Do not operate a summer exhaust fan.
6. Follow the lighting instructions. Place the appliance
being inspected in operation. Adjust thermostat so
appliance shall operate continuously.
7. Test for spillage from draft hood appliances at the
draft hood relief opening after 5 minutes of main
burner operation. Use the flame of a match or
candle.
8. If improper venting is observed during any of the
above tests, the venting system must be corrected in
accordance with the National Fuel Gas Code ANSI
Z223.1/NFPA 54 and/or National Gas and Propane
Installation Code CSA B149.1-15.
9. After it has been determined that each appliance
connected to the venting system properly vents
when tested as outlined above, return doors,
windows, exhaust fans, fireplace dampers and any
other gas burning appliance to their previous
conditions of use.

AVERTISSEMENT
11
Thermostat Location
The thermostat should be placed approximately ve feet
from the oor on a vibration-free, inside wall in an area
having good air circulation. Do not install the thermostat
where it may be inuenced by any of the following:
• Drafts, or dead spots behind doors, in corners, or under
cabinets.
• Hot or cold air from registers.
• Radiant heat from the sun.
• Light xtures or other appliances.
• Radiant heat from a replace.
• Concealed hot or cold water pipes, or chimneys.
• Unconditioned areas behind the thermostat, such as
an outside wall. Consult the instructions packaged
with the thermostat for mounting instructions and
further precautions.
COMBUSTION & VENTILATION REQUIREMENTS
Improved construction and additional insulation in buildings
have reduced heat loss by reducing air inltration and escape
around doors and windows. These changes have helped in
reducing heating/cooling costs but have created a problem
supplying combustion and ventilation air for gas red and
other fuel burning appliances. Appliances that pull air out
of the house (clothes dryers, exhaust fans, replaces, etc.)
increase the problem by starving appliances for air.
House depressurization can cause back drafting or improper
combustion of gas-red appliances, thereby exposing
building occupants to gas combustion products that could
include carbon monoxide.
If this furnace is to be installed in the same space with other
gas appliances, such as a water heater, ensure there is an
adequate supply of combustion and ventilation air for the
other appliances. Refer to the latest edition of the National
Fuel Gas Code NFPA 54/ANSI Z223.1 or CAN/CSA B1491-
15 Installation Codes or applicable provisions of the
local building codes for determining the combustion air
requirements for the appliances.
Most homes will require outside air be supplied to the
furnace area by means of ventilation grilles or ducts
connecting directly to the outdoors or spaces open to the
outdoors such as attics or crawl spaces.
INSTALLATION POSITIONS
This furnace may be installed in an upright position or
horizontal on either the left or right side panel. Do not
install this furnace on its back. For upright upow furnaces,
return air ductwork may be attached to the side panel(s)
and/or basepan. For horizontal upow furnaces, return
air ductwork must be attached to the basepan. For
both upright or horizontal counterow furnaces, return
ductwork must be attached to the basepan (top end of
the blower compartment). NOTE: Ductwork must never
be attached to the back of the furnace. Contact your
distributor for proper airow requirements and number of
required ductwork connections. Refer to “Recommended
Installation Positions” gure for appropriate installation
positions, ductwork connections, and resulting airow
arrangements.
HORIZONTAL APPLICATIONS &
CONSIDERATIONS

ANGLE
IRON
(3
PLACES
)
X X
Figure 2
When installing a furnace horizontally, additional consideration
must be given to the following:
Furnace Suspension
If suspending the furnace from rafters or joists, use 3/8”
threaded rod and 2”x2”x1/8” angle iron as shown in the
following diagram. The length of rod will depend on the
application and the clearances necessary.
If the furnace is installed in a crawl space it must be
suspended from the oor joist or supported by a concrete
pad. Never install the furnace on the ground or allow it to
be exposed to water.
Front Cover Pressure Switch Tube Location
When a furnace is installed horizontally with left side down,
the front cover pressure switch tube must be re-located to
the lower port of the collector box cover.
1. Remove tube from front cover pressure switch and
collector box cover.
2. Remove rubber plug from bottom collector box port
and install on top collector box port.
12
3. Locate 24” x 1/4” tube in bag assembly.
4. Install one end on front cover pressure switch.
5. Route tube to lower port on collector box cover and
cut o excess tubing.
Drain Trap and Lines
In horizontal applications the condensate drain trap is
secured to the furnace side panel, suspending it below the
furnace. A minimum clearance of 5.5” below the furnace
must be provided for the drain trap. Additionally, the
appropriate downward piping slope must be maintained
from the drain trap to the drain location. Refer to
Condensate Drain Trap and Lines for further details. If the
drain trap and drain line will be exposed to temperatures
near or below freezing, adequate measures must be taken
to prevent condensate from freezing.
Leveling
Leveling ensures proper condensate drainage from the
heat exchanger. For proper ue pipe drainage, the furnace
must be level lengthwise from end to end. The furnace
should have a slight tilt from back to front with the access
doors downhill from the back panel approximately 1/2
to 3/4 inches. The slight tilt allows the heat exchanger
condensate, generated in the recuperator coil, to ow
forward to the recuperator coil front cover.

Recommended Installation Positions
Alternate Electrical and Gas Line Connections
This furnace has provisions allowing for electrical and gas
line connections through either side panel. In horizontal
applications the connections can be made either through
the “top” or “bottom” of the furnace.
Drain Pan
A drain pan must be provided if the furnace is installed
above a conditioned area. The drain pan must cover the
entire area under the furnace (and air conditioning coil if
applicable).
Freeze Protection
If the drain line is routed through an area which may see
temperatures near or below freezing, precautions must be
taken to prevent condensate from freezing within the drain
line.

WARNING
This manual will refer to the pipe that discharges products
of combustion to the outdoors as the “vent” pipe or
“ue” pipe. The pipe that supplies air for combustion
to the furnace will be referred to as the “intake” pipe or
“combustion air” pipe.
This furnace is dual certied and may be installed as a
non-direct vent (single pipe) or direct vent (dual pipe)
appliance.
MATERIALS – INSTALLATIONS IN THE
U.S.A.
PVC, CPVC, or ABS pipe & ttings are typically used as
venting and intake pipe materials. All 90° elbows must
be medium or long radius types. A medium radius elbow
should measure ~3-1/16” minimum from the plane of
one opening to the center line of the other opening for 2”
diameter pipe, and ~4-9/16” minimum for 3” pipe.
In addition to these materials, Innoue® by Centrotherm
Eco Systems and PolyPro® by M&G Duravent are
also approved vent and combustion air materials for
installations in the U.S.A. Manufacturers Installation
instructions for these products must be followed. These
products have specic instructions for installing, joining
and terminating. Do not mix materials or components of
one manufacturer with materials or components of another
manufacturer. Refer to the following chart for plastic pipe &
ttings specications.
MATERIALS – INSTALLATIONS IN CANADA
All installations in Canada must conform to the
requirements of CAN/CSA B149.1-15 code. All vent
components, including primer and cement, must be listed
to ULC S636. The certied pipe and ttings should be
clearly marked with the ULC standard “S636”. The primer
and cement used must be of the same manufacturer as
the vent system. For Royal Pipe System 636; use GVS-
65 Primer (Purple) and GVS-65 PVC Solvent Cement.
For IPEX System 636, use PVC/CPVC Primer, Purple
or clear. Use PVC Solvent cement (Gray). For Canadian
installations, ABS may be used as a combustion air pipe
only. ABS is not an approved vent material in Canada.
If ABS is used as a combustion air pipe, it must be CSA
certied. Always follow the manufacturer’s instructions
in the use of primer and cement. Do not use primer and
cement around potential sources of ignition. Do not use
primer or cement beyond its expiration date.

PIPE INSTALLATION
This furnace is manufactured with 2” CPVC vent & intake
couplings. Use transition cement to connect PVC or ABS
pipe to these ttings. For furnaces requiring installation
of 3” pipe, the transition from 2” to 3” should be done as
close to the furnace as possible, and only when the piping
is sloped enough to prevent condensation from collecting.
This furnace must not be connected to Type B, BW, or
L vent or vent connector, and must not be vented into
masonry chimney. A masonry chimney may be used as
a chase or passage way for approved venting materials
providing the masonry chimney is not also being used to
vent products of combustion. Never common vent this
appliance with another appliance. Never use a vent which
is used by a solid fuel appliance.
Piping may run vertically or horizontally and must be
adequately supported to prevent strain on joints, sagging,
separation, and detachment from the furnace. Horizontal
runs of piping must be supported every three to ve
feet. Condensation within the furnace secondary heat
exchanger and in the vent pipe is a normal occurrence.
Vent pipe must be installed to maintain a minimum 1/4
inch per foot downward slope toward the furnace to return
condensate to the furnace’s drain system. Condensation
may also occur in the intake pipe. This commonly takes
place during the summer months when humid air enters
an intake pipe that runs through a cool basement or other
conditioned space. If the combustion air intake pipe is to
be installed above a nished ceiling or other area where
dripping of condensate will be objectionable, insulating
the combustion air pipe may be necessary. Use 1/2” thick
closed cell foam insulation where required. Refer to intake
pipe options for using the RF000142 kit and managing
condensation.

Pipe Sizing
Consult tables 4 & 5 to determine what diameter piping is
required for your installation. Lengths shown in the chart
apply to single pipe & two pipe installations. In a two pipe
installation the length shown refers to only one pipe, vent
or intake. Both pipes would normally be equal in length, if
dierent, then the longest pipe must be within the limits of
table 4. It is preferable to up-size from 2” to 2.5” or 3” pipe
if the pipe length & elbow count are near maximum. This
will help avoid nuisance pressure switch opening caused
by prevailing winds & sudden changes in atmospheric
pressure.

Vent Pipe Connection
The vent pipe outlet is sized to accept 2” pipe. Secure vent
pipe directly into the furnace tting with the appropriate
glue. Alternately, a small section of 2” pipe may be glued
in the furnace socket and a rubber coupling installed to
allow removal for future service. Piping should be routed in
a manner to avoid contact with refrigerant lines, metering
devices, condensate drain lines, etc. If necessary,
clearances may be increased by creating an oset using
two 45° elbows (Figure 7).

Figure 7
COMBUSTION AIR PIPE CONNECTION
If the furnace is being installed without a combustion air
pipe, a 90° elbow should be used on the combustion air
intake to guard against blockage.
On up ow / horizontal models, secure the combustion
air intake pipe to the air intake coupling using a rubber
coupling supplied with the furnace. The rubber coupling
may be omitted by inverting the intake coupling and gluing
pipe directly to it. Piping may also be glued to the intake
coupling in its original position by using a plastic coupling.
On counterow units secure the combustion air intake
pipe to the air intake coupling using the rubber coupling
and worm gear hose clamps provided with the unit. The
counterow rubber coupling allows service removal of air
intake piping internal to the furnace blower compartment.
The combustion air intake pipe can also be secured
directly to the counterow unit air intake pipe coupling.
16
Combustion Air Intake Options
The RF000142 coupling (Figure 9) can be secured
directly to the furnace intake coupling if condensation/
rain water is a concern. If the RF000142 is used on the
combustion air inlet, it must be installed with the arrow
pointing up. It should be noted, the combustion air will
actually be moving in a direction opposite of the arrow
on the RF000142 coupling. It must have a eld supplied,
trapped drain tube free-draining to a proper condensate
disposal location. A loop in the drain tube can serve as a
trap. The unused RF000142 drain tting must be capped.
A eld supplied tee installed in the intake pipe is also an
acceptable method of catching condensation. It must have
a eld supplied, trapped drain tube or pipe, free-draining to
a proper condensate disposal location. A loop in the drain
tube can serve as a trap.

Alternate Vent & Intake Pipe Connections
(Upflow/Horizontal models only)
When installing a furnace horizontally with the left side
down, alternate ue and combustion air pipe connections
may be used. This method allows the ue and combustion
air piping to be run vertically through the side of the
furnace (facing up in horizontal left). The alternate vent
location is the 3” hole directly in line with the induced draft
blower outlet.
When using the horizontal alternate vent conguration,
you must use the RF000142 vent drain kit. See Figures
8-11 & follow steps below.
NOTE: In the horizontal left installation position, a
means of condensate collection must be provided
to keep vent pipe condensate from entering the draft
inducer housing. If the vent drain elbow is eliminated
from the installation, the RF000142 kit must be used.

Pipe Termination
Products of combustion must always be vented outside. A
vent pipe must never terminate in an attic, crawl space, or
any other part of a dwelling. Follow the vent pipe & intake
pipe termination requirements listed below as well as all
applicable local, State and National codes.
All terminations (vent and/or intake) must be located at
least 12” above ground level or the anticipated snow level.
All vent terminations (non-direct and direct vent) must
terminate at least 3 feet above any forced air inlet located
within 10 feet.
The vent termination of a non-direct vent application must
terminate at least 4 feet below, 4 feet horizontally from, or
1 foot above any door, window, or gravity air inlet into any
building.
18
The vent termination of a direct vent application must
terminate at least 12” from any opening through which
ue gases may enter a building (door, window, or gravity
air inlet).
The vent termination of vent pipe run vertically through
a roof must terminate at least 12” above the roof line (or
the anticipated snow level) and be at least 12” from any
vertical wall (including any anticipated snow build up).
A vent termination shall not terminate over public
walkways or over an area where condensate or vapor
could create a nuisance or hazard or could be detrimental
to the operation of regulators, relief valves, or other
equipment.
The combustion air intake termination of a direct vent
application should not terminate in an area which is
frequently dusty or dirty.
Vent & combustion air pipes may terminate vertically
through a roof, or horizontally through an outside wall.
The combustion air intake and vent pipe terminations
must be in the same atmospheric pressure zone. Vertical
vent pipe terminations should be as shown in gure 14.
The penetration of pipes through the roof must be sealed
water tight with proper ashing such as is used with a
plastic plumbing vent.
Horizontal vent pipe terminations should be as shown in
the following gures. To secure the pipe passing through
the wall and prohibit damage to piping connections, a
coupling should be installed on either side of the wall and
solvent cemented to a length of pipe connecting the two
couplings. The length of pipe should be the wall thickness
plus the depth of the socket ttings to be installed on the
inside and outside of the wall. The wall penetration should
be sealed with silicone caulking material.

CONDENSATE DRAIN LINES & DRAIN
TRAP
A condensing gas furnace achieves its high level
of eciency by extracting heat from the products of
combustion to the point where condensation takes place.
The condensate must be collected in the furnace drain trap
and routed to an appropriate drain location in compliance
with local and national codes.
Follow the bullets listed below when installing the drain
system. Refer to the following sections for specic details
concerning furnace drain trap installation and drain hose
hook ups.
• The drain trap supplied with the furnace must be used.
• The drain trap must be primed at time of installation.
• The drain line between furnace and drain location must
meet local and nation codes.
• The drain line between furnace and drain location must
maintain a 1/4 inch per foot downward slope toward the
drain.
• Do not trap the drain line in any other location than at the
drain trap supplied with the furnace.
• If the drain line is routed through an area which may see
temperatures near or below freezing, precautions must
be taken to prevent condensate from freezing within the
drain line.
• If an air conditioning coil is installed with the furnace,
a common drain may be used. An open tee must be
installed in the drain line, near the cooling coil, to relieve
positive air pressure from the coil’s plenum. This is
necessary to prohibit any interference with the function of
the furnace’s drain trap.
NOTE: In vertical installations, air conditioning coil
condensate may drain into the furnace trap as long as
there is a trap between the coil and the furnace trap
and the drain pipe is not terminating below the water
level of the furnace trap.

General Drain Information
All furnace models come with a factory installed drain trap.
For vertical installations, the trap will remain in the factory
position except for a counterow when the installer desires
the drain to exit the right side. All furnace models installed
horizontally require the trap to be relocated. Many drain
hoses have a built–in grommet which will provide a cabinet
seal when installed. See instructions below for your model
and installation position.
NOTE: Both sides of the drain trap must be primed
prior to initial furnace start up

Field Supplied Drain
Drain the furnace and air conditioning coil if applicable,
in compliance with code requirements. In horizontal or
counterow installations, a eld installed rubber coupling
will allow the drain trap to be removed for cleaning. The
drain trap must be primed before initial furnace start up.
When an air conditioning coil drain is connected to the
eld supplied furnace drain, it must be vented. An open
tee must be installed at a height no higher than the bottom
of the furnace collector box to prevent air conditioning
condensate from backing up into the furnace, if the
common drain was blocked.
Upflow Model Installed Vertically
The trap and factory installed hoses remain as shipped.
The furnace drain may exit either the right or left side of
the furnace cabinet. Both sides of the cabinet have two
.875” diameter holes which can be used interchangeably
for drain and low voltage wiring purposes. If a higher drain
exit is needed, a .875” diameter hole may be added in the
area shown in Figure 24. Any unused cabinet opening
must be sealed. Do not allow drain hose to sag or trap
water.

WARNING
Fossil Fuel Applications
This furnace can be used in conjunction with a heat pump
in a fossil fuel application. A fossil fuel application refers to
a combined gas furnace and heat pump installation which
uses an outdoor temperature sensor to determine the most
cost ecient means of heating (heat pump or gas furnace).
A heat pump thermostat is required to properly use a
single-stage furnace in conjunction with a heat pump.
Refer to the fossil fuel kit installation instructions for
additional thermostat requirements.
Strictly follow the wiring guidelines in the fossil fuel kit
installation instructions. All furnace connections must be
made to the furnace two-stage integrated control module
and the “FURNACE” terminal strip on the fossil fuel control
board.
28
Inlet gas supply pressures must be maintained within
the ranges specied in the following table. The supply
pressure must be constant and available with all other
household gas red appliances operating. The minimum
gas supply pressure must be maintained to prevent
unreliable ignition. The maximum must not be exceeded
to prevent unit overring.

WARNING
HIGH ALTITUDE INSTALLATION
When this furnace is installed at high altitude, the
appropriate High Altitude Kit including orices and a
pressure switch(s) must be installed. These changes are
necessary to compensate for the natural reduction in the
density of both the gas fuel and the combustion air at
higher altitude.
Installation of this furnace at altitudes above 7000 ft (2134
m), shall be made in accordance with the Listed High
Altitude Conversion Kit available with this furnace.
Do not de-rate the furnace by adjusting the manifold
pressure to a lower pressure than specied on the furnace
rating plate. The combination of the lower air density and
a lower manifold pressure will prohibit the burner orice
from drawing the proper amount of air into the burner. This
may cause incomplete combustion, ashback, and yellow
tipping.
In some areas the gas supplier may articially derate the
gas in an eort to compensate for the eects of altitude.
If the gas is articially derated, the appropriate orice size
must be determined based upon the BTU/ft³ content of
the derated gas and the altitude. Refer to the National
Fuel Gas Code, NFPA 54/ANSI Z223.1, and information
provided by the gas supplier to determine the proper
orice size. A dierent pressure switch may be required
at high altitude regardless of the BTU/ft³ content of the
fuel used. Consult the furnace Specication Sheet. All
conversions must be performed by a qualied installer, or
service agency.
Propane Gas Conversion
This furnace is shipped from the factory congured for
natural gas at standard altitude. To operate this furnace
on L.P. gas, a LPM-07 LP Conversion kit must be used.
Propane gas installations require an orice and spring
change to compensate for the energy content dierence
between natural and propane gas.
Twinning
Two furnaces of the same model may be twinned. The
integrated control board has a 3/16” terminal labeled
“TWIN” located beside the low voltage thermostat
connection strip. Twinning allows simultaneous operation
of two furnaces and forces the indoor blower motors of
each furnace to operate synchronously into a common
duct system. Using the twinning function will require only
eld installed wiring with no external kits or parts. The
staging and speed tap options must be set the same on
both furnaces.
NOTE: Each furnace must be connected to it’s own 115
VAC power supply. The L1 connection to each furnace
must be in phase (connected to circuit breakers on the
same 115 VAC service panel phase leg). To verify that
the furnaces are in phase, check from L1 to L1 on each
furnace with a voltmeter. If the furnaces are in phase,
the voltage between both furnaces will be ZERO.

INLET GAS SUPPLY PRESSURE
The furnace rating plate includes the approved furnace gas
input rating and gas types. The furnace must be equipped
to operate on the type of gas applied. This includes any
conversion kits required for alternate fuels and/or high
altitude.
29
For furnaces being converted to LP gas, it is strongly
recommended that a LPLP03 kit also be installed. The
use of this kit will prevent the furnace from ring when
the LP gas supply pressure is too low to support proper
combustion.
All conversions must be performed by a qualied installer,
or service agency.
Gas Valve
This unit is equipped with a 24 volt gas valve controlled
during furnace operation by the integrated control
module. As shipped, the valve is congured for natural
gas. The valve is eld convertible for use with propane
gas by replacing the regulator spring with a propane
gas spring from an appropriate manufacturer’s propane
gas conversion kit. Taps for measuring the gas supply
pressure and manifold pressure are provided on the valve.
The gas valve has a manual ON/OFF control located on
the valve itself. This control may be set only to the “ON”
or “OFF” position. Refer to the lighting instructions label
or Startup Procedure & Adjustment for use of this control
during start up and shut down periods.
Gas Piping Connections
The gas piping supplying the furnace must be properly sized
based on the gas ow required, specic gravity of the gas, and
length of the run. The gas line installation must comply with
local codes, or in their absence, with the latest edition of the
National Fuel Gas Code, NFPA 54/ANSI Z223.1 or CAN/CSA
B149.1-15 in Canada.
To connect the furnace to the building’s gas piping, the
installer must supply a ground joint union, drip leg, manual
shuto valve, and line and ttings to connect to gas valve.
In some cases, the installer may also need to supply a
transition piece from 1/2” pipe to a larger pipe size.
The following stipulations apply when connecting gas
piping. Refer to Gas Piping Connections gure for typical
gas line connections to the furnace.
• Gas piping must be supported external to the furnace
cabinet so that the weight of the gas line does not
distort the burner rack, manifold or gas valve.
• Use black iron or steel pipe and ttings for building
piping. Where possible, use new pipe that is properly
chamfered, reamed, and free of burrs and chips. If
old pipe is used, be sure it is clean and free of rust,
scale, burrs, chips, and old pipe joint compound.
• Use pipe joint compound on male threads ONLY.
Always use pipe joint compound (pipe dope) that
is APPROVED FOR ALL GASES. DO NOT apply
compound to the rst two threads.
• Use ground joint unions.
• Install a drip leg to trap dirt and moisture before it can
enter the gas valve. The drip leg must be a minimum
of three inches long.
• Install a 1/8” NPT pipe plug tting, accessible for test
gauge connection, immediately upstream of the gas
supply connection to the furnace.
• Always use a back-up wrench when making the
connection to the gas valve to keep it from turning.
The orientation of the gas valve on the manifold must
be maintained as shipped from the factory. Maximum
torque for the gas valve connection is 375 in-lbs;
excessive over-tightening may damage the gas valve.
• Install a manual shuto valve between the gas
meter and unit within six feet of the unit. If a union
is installed, the union must be downstream of the
manual shuto valve, between the shuto valve and
the furnace.
• Tighten all joints securely.

Connect the furnace to the building piping by one of
the following methods:
─ Rigid metallic pipe and ttings.
─ Semi-rigid metallic tubing and metallic ttings.
Aluminum alloy tubing must not be used in
exterior locations. In order to seal the grommet
cabinet penetration, rigid pipe must be used to
reach the outside of the cabinet. A semi-rigid
connector to the gas piping may be used from
there.
• Use listed gas appliance connectors in accordance
with their instructions. Connectors must be fully in
the same room as the furnace.
• Protect connectors and semi-rigid tubing against
physical and thermal damage when installed. Ensure
aluminum-alloy tubing and connectors are coated to
protect against external corrosion when in contact
with masonry, plaster, or insulation, or subjected to
repeated wetting by liquids such as water (except rain
water), detergents, or sewage.
30
The gas piping may enter the left or right side of the
furnace cabinet. The installer must supply rigid pipe long
enough to reach the outside of the cabinet to seal the grommet
cabinet penetration. A semi-rigid connector to the gas piping
can be used outside the cabinet per local codes. 1/2” NPT
pipe and ttings are required. For models with an “L”
shaped manifold, a 4 1/2” long nipple is required. For
models with a hook shaped manifold, a 2” long nipple is
required.
A semi-rigid connector to the gas piping can be used
outside the cabinet per local codes. From the elbow, the
length of pipe and the ttings required will vary by the side
chosen, location of union and cabinet width. The union
may be placed inside or outside of the cabinet.

For satisfactory operation, propane gas pressure must be
10” WC at the furnace manifold with all gas appli ances in
operation. Maintaining proper gas pressure depends on
three main factors:
1. Vaporization rate, depending on temperature of the
liquid, and “wetted surface” area of the con tainer or
containers.
2. Proper pressure regulation. (Two-stage regulation is
recommended for both cost and eciency).
3. Pressure drop in lines between regulators, and
between second stage regulator and the appliance.
Pipe size will depend on length of pipe run and total
load of all appliances.
Complete information regarding tank sizing for vaporiza-
tion, recommended regulator settings, and pipe sizing is
available from most regulator manufacturers and propane
gas suppliers.
Since propane gas will quickly dissolve white lead and
most standard com mercial compounds, special pipe dope
must be used. Always use a pipe thread sealant approved
for all gases.
Refer to the illustration for typical propane gas
installations and piping.

CIRCULATING AIR & FILTERS
Duct work - Air Flow
Duct systems and register sizes must be properly
designed for the CFM and external static pressure rat ing
of the furnace. Design the ductwork in accor dance with the
recommended methods of “Air Conditioning Contractors
of America” Manual D.
32
Install the duct system in accordance with Standards of
the National Board of Fire Underwriters for the Installation
of Air Conditioning, Warm Air Heating and Ventilating
Systems. Pamphlets No. 90A and 90B.
A closed return duct system must be used, with the return
duct connected to the furnace. NOTE: Ductwork must
never be attached to the back of the furnace. For upow
installations requiring 1800 CFM or more, use either two
side returns or bottom return or a combination of side /
bottom. Flexible joints may be used for supply and return
con nections to reduce noise transmission. To prevent the
blower from inter fering with combustion air or draft when a
central return is used, a connecting duct must be installed
between the unit and the utility room wall. Never use a
room, closet, or alcove as a return air chamber.
Checking Duct Static
Refer to your furnace rating plate for the maximum ESP
(external duct static) rating.
Total external static refers to everything external to the
furnace cabinet. Cooling coils, lters, ducts, grilles,
registers must all be considered when reading your total
external static pressure. The supply duct pressure must
be read between the furnace and the cooling coil. This
reading is usually taken by removing the “A” shaped block
o plate from the end on the coil; drilling a test hole in
it and reinstalling the block o plate. Take a duct static
reading at the test hole. Tape up the test hole after your
test is complete. The negative pressure must be read
between the lter and the furnace blower.
Too much external static pressure will result in insucient
air that can cause excessive temperature rise. This can
cause limit switch tripping and heat exchanger failure.
To determine total external duct static pressure, proceed
as follows;
1. With clean lters in the furnace, use a manometer to
measure the static pressure of the return duct at the
inlet of the furnace. (Negative Pressure)
2. Measure the static pressure of the supply duct.
(Positive Pressure)
3. The dierence between the two numbers is .4” w.c.
Example:
-1
0
1 2
3
Difference is 4
Static reading from return duct = -.1” w.c.
Static reading from supply duct = .3” w.c.
Total external static pressure on this system = .4” w.c.
NOTE: Both readings may be taken simultaneously
and read directly on the manometer if so desired. If an
air conditioner coil or Electronic Air Cleaner is used in
conjunction with the furnace, the readings must also
include theses components, as shown in the following
drawing.
4. Consult proper tables for the quantity of air.
If the total external static pressure exceeds the maximum
listed on the furnace rating plate, check for closed
dampers, registers, undersized and/or oversized poorly
laid out duct work.
The temperature rise of the furnace must be within the
temperature rise range listed on the furnace rating plate.

Bottom Return Air Opening [Upflow Models]
The bottom return air opening on upow models utilizes
a “lance and cut” method to remove sheet metal from the
duct opening in the base pan. To remove, simply press
out the lanced sections by hand to expose the metal strips
retaining the sheet metal over the duct opening. Using
tin snips, cut the metal strips and remove the sheet metal
covering the duct opening. In the corners of the opening,
cut the sheet metal along the scribe lines to free the duct
anges. Using the scribe line along the duct ange as a
guide, unfold the duct anges around the perimeter of the
opening using a pair of seamer pliers or seamer tongs.
NOTE: Airow area will be reduced by approximately
18% if duct anges are not unfolded. This could cause
performance issues and noise issues.

When the furnace is used in connection with a cooling unit,
the furnace should be installed in parallel with or on the
upstream side of the cooling unit to avoid condensa tion
in the heating element. With a parallel ow arrange ment,
the dampers or other means used to control the ow of
air must be adequate to prevent chilled air from entering
the furnace and, if manually operated, must be equipped
with means to prevent operation of either unit unless the
damper is in the full heat or cool position.
When the furnace is installed without a cooling coil, it is
recommended that a removable access panel be provided
in the outlet air duct. This opening shall be accessible
when the furnace is installed and shall be of such a size
that the heat exchanger can be viewed for visual light
inspection or such that a sampling probe can be inserted
into the air stream. The access panel must be made to
prevent air leaks when the furnace is in operation.
When the furnace is heating, the temperature of the return
air entering the furnace must be between 55°F and 100°F.
FILTERS - READ THIS SECTION BEFORE
INSTALLING THE RETURN AIR DUCT
WORK
Filters must be used with this furnace. Discuss lter
maintenance with the building owner. Filters do not ship
with this furnace, but must be provided, sized and installed
externally by the installer. Filters must comply with UL900
or CAN/ULCS111 standards. Damage or repairs due to
the installation of the furnace without lters is not covered
under the warranty.
On upow units, guide dimples locate the side return
cutout locations. Use a straight edge to scribe lines
connecting the dimples. Cut out the opening on these
lines. NOTE: An undersized opening will cause reduced
airow.
Refer to the Filter Sizing Chart to determine lter area

Consider installing an air cleaner with deep-pleated media
lter at the time of furnace installation. A deep-pleated
lter with a MERV rating of 8 (minimum) will often provide
better ltration to protect equipment and the air distribution
system than a standard 1” lter and often has lower static
pressure loss than a 1” lter. Also a deep-pleated lter
will typically require less frequent replacement intervals.
Avoid using highly restrictive 1” lters which produce static
pressure loss greater than .25” W.C. In some installations
the minimum lter size required (consult lter sizing chart
above) will not lend itself to a lter installation on the side
of the furnace. The installation of a centrally installed air
cleaner cabinet or a return duct lter installation may oer
more practicality.
34
Clean Comfort™ brand MERV 11 air cleaners have
5¼” media lters and are available in the following
congurations. Consult your distributor for information on
our complete line of IAQ Clean Comfort™ products.
Depending on the installation and/or customer preference,
diering lter arrangements can be applied. Filters can
be installed in the central return register or a side panel
external lter rack kit (upows). As an alternative a media
air lter or electronic air cleaner can be used as the
requested lter.

STARTUP PROCEDURE & ADJUSTMENT
Furnace must have a 115 VAC power supply properly
connected and grounded. Proper polarity must be
maintained for correct operation. In addition to the
following start-up and adjustment items, refer to further
information in Operational Checks section.
Furnace Cabinet
Check that all furnace cabinet sealing components are in
place (plugs, grommets, gaskets). NOTE; If the furnace
bottom panel has not been removed for a return duct
connection, all perforations must be sealed with duct
sealant compound or other suitable method to prevent air
leakage. For optimal performance verify that all do gaskets
are properly in place and replace as needed to prevent air
leakage.
Drain Trap Priming
The drain trap must be primed prior to furnace startup.
To prime, ll both sides of the drain trap with water.
This ensures proper furnace drainage upon startup and
prohibits the possibility of ue gases escaping through the
drain system.
Furnace Operation
Purge gas lines of air prior to startup. Be sure not purge
lines into an enclosed burner compartment. Follow
NFPA 54, National Fuel Gas Code 8.1 for proper purging
methods. In Canada, follow approved purging methods in
B149.1-15.
Check for leaks using an approved chloride-free soap and
water solution, an electronic combustible gas detector,
or other approved method. Verify that all required kits
(propane gas, high altitude, etc.) have been appropriately
installed.

The typical value range for 1 cu. ft. of natural gas is around
1000 BTU. Check with your gas utility, if possible. In this
example, the furnace is consuming 78,000 BTUH.
NOTE: The nal manifold pressure cannot vary by
more than ± 0.3” w.c. for Natural and + 0.5” for LP from
the specied setting. Consult your local gas supplier
if additional input rate adjustment is required.
4. Turn ON gas to and relight all other appliances
turned o in step 1. Be certain that all appliances
are functioning properly and that all pilot burners are
operating.
Temperature Rise
Temperature rise must be within the range specied on the
unit rating plate. An incorrect temperature rise may result
in condensing in or overheating of the heat exchanger.
An airow and temperature rise table is provided in the
Specication Sheet applicable to your model. Determine
and adjust temperature rise as follows:
1. Operate furnace with burners ring for approximately
ten minutes. Ensure all registers are open and all
duct dampers are in their nal (fully or partially open)
position.
2. Place thermometers in the return and supply ducts
as close to the furnace as possible. Thermometers
must not be inuenced by radiant heat by being able
to “see” the heat exchanger.
3. Subtract the return air temperature from the supply
air temperature to determine the air temperature
rise. Allow adequate time for thermometer readings
to stabilize.
4. Adjust temperature rise by adjusting the circulator
blower speed. Increase blower speed to reduce
temperature rise. Decrease blower speed to
increase temperature rise. Refer to Startup

Gas Input Rate Measurement (Natural Gas Only)
The actual gas input rate to the furnace must never be
greater than that specied on the unit rating plate. To
measure natural gas input using the gas meter, use the
following procedure.
1. Turn OFF the gas supply to all other gas-burning
appliances except the furnace.
2. While the furnace is operating at high re rate, time
and record one complete revolution of the gas meter
dial, measuring the smallest quantity, usually the dial
that indicates 1/2 cu. ft. per revolution. You will use
this number to calculate the quantity of gas in cubic
ft. if the furnace would consume if it ran steadily for
one hour (3600 seconds).
3. If the 1/2 cu. ft. dial was used, multiply your number
x 2.
EXAMPLE: If it took 23 seconds to complete one
revolution of the 1/2 ft. dial (23 x 2 = 46).
This tells us that at this rate, it would take 46 seconds to
consume one cu. ft. of gas. 3600 / 46 = 78.
This tells us that in one hour, the furnace would consume
78 cu. ft. of gas.
39
OPERATIONAL CHECKS
The burner ames should be inspected with the burner
compartment door installed. Flames should be stable,
quiet, soft, and blue (dust may cause orange tips but
they must not be yellow). Flames should extend directly
outward from the burners without curling, oating, or lifting
o. Flames must not impinge on the sides of the heat
exchanger ring tubes.
SAFETY CIRCUIT DESCRIPTION
A number of safety circuits are employed to ensure safe
and proper furnace operation. These circuits serve to
control any potential safety hazards and serve as inputs
in the monitoring and diagnosis of abnormal function.
These circuits are continuously monitored during furnace
operation by the integrated control module.
WARNING
Do not bypass any safety circuit.
Integrated Control Module
The integrated control module is an electronic device
which, if a potential safety concern is detected, will
take the necessary precautions and provide diagnostic
information through an LED.
Primary Limit
The primary limit control is located on the partition panel
and monitors heat exchanger compartment temperatures.
It is a normally-closed (electrically), automatic reset,
temperature-activated sensor. The limit guards against
overheating as a result of insucient conditioned air
passing over the heat exchanger.
Auxiliary Limit
The auxiliary limit controls are located on or near the
circulator blower and monitors blower compartment
temperatures. They are a normally-closed (electrically),
manual-reset sensors. These limits guard against
overheating as a result of insucient conditioned air
passing over the heat exchanger.
Rollout Limit
The rollout limit controls are mounted on the burner/
manifold assembly and monitor the burner ame. They are
normally-closed (electrically), manual-reset sensors. These
limits guard against burner ames not being properly
drawn into the heat exchanger.
Pressure Switches
The pressure switches are normally-open (closed during
operation) negative air pressure-activated switches. They
monitor the airow (combustion air and ue products)
through the heat exchanger via pressure taps located on
the induced draft blower and the coil front cover. These
switches guard against insucient airow (combustion
air and ue products) through the heat exchanger and/or
blocked condensate drain conditions.
Flame Sensor
The ame sensor is a probe mounted to the burner/
manifold assembly which uses the principle of ame
rectication to determine the presence or absence of
ame.
MAINTENANCE
Annual Inspection
The furnace should be inspected by a qualied installer, or
service agency at least once per year. This check should
be performed at the beginning of the heating season.
This will ensure that all furnace components are in proper
working order and that the heating system functions
appropriately. Pay particular attention to the following
items. Repair or service as necessary.
• Flue pipe system. Check for blockage and/or leakage.
Check the outside termination and the connections at
and internal to the furnace.
• Heat exchanger. Check for corrosion and/or buildup
within the heat exchanger passageways.
• Burners. Check for proper ignition, burner ame, and
ame sense.
• Drainage system. Check for blockage and/or leakage.
Check hose connections at and internal to furnace.
• Wiring. Check electrical connections for tightness
and/or corrosion. Check wires for damage.
• Filters.
FILTERS
Filter Maintenance
Improper lter maintenance is the most common cause of
inadequate heating or cooling performance. Filters should
be cleaned (permanent) or replaced (disposable) every
two months or as required. When replacing a lter, it must
be replaced with a lter of the same type and size.
Filter Removal
Depending on the installation, diering lter arrangements
can be applied. Filters can be installed in either the central
return register or a side panel external lter rack (upow
only). A media air lter or electronic air cleaner can be
used as an alternate lter. Follow the lter sizes given in
the Recommended Minimum Filter size table to ensure
proper unit performance.
To remove lters from an external lter rack in an upright
upow installation, follow the directions provided with
external lter rack kit.
40
Flame Sensor (Qualified Servicer Only)
Under some conditions, the fuel or air supply can create a
nearly invisible coating on the ame sensor. This coating
acts as an insulator causing a drop in the ame sense
signal. If the ame sense signal drops too low the furnace
will not sense ame and will lock out. The ame sensor
should be carefully cleaned by a qualied servicer using
emery cloth or steel wool. Following cleaning, the ame
sense signal should be as indicated in the Specications
Sheet.
Flue Passages (Qualified Servicer Only)
The heat exchanger ue passageways should be
inspected at the beginning of each heating season.
BEFORE LEAVING AN INSTALLATION
• Cycle the furnace with the thermostat at least three
times. Verify cooling and fan only operation.
• Review the Owner’s Manual with the homeowner and
discuss proper furnace operation and maintenance.
• Leave literature packet near furnace.
REPAIR AND REPLACEMENT PARTS
• When ordering any of the listed functional parts, be
sure to provide the furnace model, manufacturing,
and serial numbers with the order.
• Although only functional parts are shown in the parts
list, all sheet metal parts, doors, etc. may be ordered
by description.
• Parts are available from your distributor.

Follow the manufacturer’s directions for service.
Burners
Visually inspect the burner ames periodically during the
heating season. Turn on the furnace at the thermostat
and allow several minutes for ames to stabilize, since any
dislodged dust will alter the ames normal appearance.
Flames should be stable, quiet, soft, and blue (dust may
cause orange tips but they must not be yellow). They
should extend directly outward from the burners without
curling, oating, or lifting o. Flames must not impinge on
the sides of the heat exchanger ring tubes.
Induced Draft and Circulator Blowers
