LP and Natural gas have an odorant added to aid in detecting a gas leak. Some people
may not physically be able to smell or recognize this odorant. If you are unsure or
unfamiliar with the smell of LP or natural gas, ask the gas supplier. Other conditions,
such as “odorant fade”, which causes the odorant to diminish in intensity, can also hide or
camouflage a gas leak.
DANGER!
LIQUEFIED PETROLEUM (LP PROPANE OR BUTANE)
AND NATURAL GAS MODELS
● Water heaters utilizing LP gas are
different from natural gas models. A
natural gas water heater will not function
safely on LP gas and vice versa.
● No attempt should ever be made to
convert the water heater from natural
gas to LP gas. To avoid possible
equipment damage, personal injury or
fire, DO NOT connect the water heater
to a fuel type not in accordance with the
unit data plate. LP for LP units. Natural
gas for natural gas units. These units are
not certified for any other fuel type.
● LP appliances should not be installed
below grade (for example, in a basement)
if such installation is prohibited by
federal, state and/or local laws, rules,
regulations or customs.
● LP gas must be used with great caution.
It is heavier than air and will collect first
in lower areas making it hard to detect at
nose level.
● Before attempting to light the water
heater, make sure to look and smell for
gas leaks. Use a soapy solution to check
all gas fittings and connections. Bubbling
at a connection indicates a leak that must
be corrected. When smelling to detect a
gas leak, be sure to sniff near the floor
also.
● Gas detectors are recommended in LP
& natural gas applications and their
installation should be in accordance
with the detector manufacturer’s
recommendations and/or local laws,
rules, regulations or customs.
● It is recommended that more than one
method, such as soapy solution, gas
detectors, etc., be used to detect leaks in
gas applications.
!
DANGER: If a gas leak is present or
suspected:
● DO NOT attempt to find the cause
yourself.
● DO NOT try to light any appliance.
● DO NOT touch any electrical switch.
● DO NOT use any phone in your building.
● Leave the house immediately and make
sure your family and pets leave also.
● Leave the doors open for ventilation
and contact the gas supplier, a qualified
service agency or the fire department.
● Stay away from the house (or building)
until the service call has been made, the
leak is corrected and a qualified agency
has determined the area to be safe.

Installing the water heater
This water heater must be installed in accordance with these instructions, local codes, utility company
requirements, and/or in the absence of local codes, use the latest edition of the American National
Standard/National Fuel Gas Code. A copy can be purchased from either the American Gas Association,
400 N. Capitol Street NW, Washington, DC 20001 as ANSI standard Z223.1 or National Fire Protection
Association, 1 Batterymarch Park, Quincy, MA 02269 as booklet NFPA 54.
Location
The water heater should not be located
in an area where leakage from the tank
or connections will result in damage to
the area adjacent to the heater or to lower
floors of the structure.
When such areas cannot be avoided it is
recommended that a suitable drain pan,
adequately drained, must be installed
under the water heater.
The water heater must be centered in the
drain pan.
The drain pan must not restrict air flow
to the combustion air inlet openings
(perforation openings) located around the
lower perimeter of the water heater.
Drain pan kits are available from the store
where the water heater was purchased, or
any water heater distributor.
Make certain the floor underneath
the water heater is strong enough to
sufficiently support the weight of the
water heater once it is filled with water.
A gas fired water heater or any other
appliance should not be installed in
a space where liquids which give off
flammable vapors are to be used or stored.
Such liquids include gasoline, LP gas
(butane or propane), paint or adhesives
and their thinners, solvents or removers.
DO NOT block or obstruct any of the
combustion air inlet openings located
around the perimeter of the water heater.
A minimum of 1 in. is required between
these combustion air inlet openings and
any obstruction.
DO NOT obstruct or block the Flammable
Vapor Sensor.
Because of natural air movement in a
room or other enclosed space, flammable
vapors can be carried some distance from
where liquids which give off flammable
vapors are to be used or stored. The open
flame of the water heater’s pilot or main
burner can ignite these vapors and create
a shut down condition of the water heater
which will not allow the water heater
to ignite until examined by a Qualified
Service Technician.
FVIR certified gas water heaters can be
installed on a residential garage floor
without the use of an 18 in (46 cm). stand
in accordance with the National Fuel Gas
Code, NFPA 54, unless otherwise directed
by State and Local code requirements. The
water heater must be located so it is not
subject to physical damage, for example,
by moving vehicles, area flooding etc.
● DO NOT install the water heater in a
location where it may be subjected to
ambient temperatures exceeding 125°F
(52°C).
● The water heater should be installed so
as to minimize the length of plastic vent
pipe and the number of vent connection
fittings required.
● Hot water lines should be insulated to
conserve water and energy.
● Protect the water heater and water lines
from exposure to freezing temperatures.
● DO NOT install the water heater in
bathrooms, bedrooms, any occupied
rooms normally kept closed, or in
unprotected outdoor areas.
● DO NOT install this water heater
outdoors.
● Minimum clearance from combustible
construction:
* "Front" clearance dimension is
measured from the water heater
jacket to the closet door.
** "Top" clearance dimension is
measured from the jacket top to the
ceiling.
If the clearances stated on the Instruction/
Warning Label, located on the front of
the heater differ, install the water heater
according to the clearances stated on the
label.
● If the water heater is to be installed
directly on carpeting, the water heater
shall be installed on a metal or wood
panel extending beyond the full width
and depth of the water heater by at least
3 in. (7.6 cm) in all directions or, if
the water heater is to be installed in an
alcove or closet, the entire floor must be
covered by a wood or metal panel.
NOTICE: For proper operation and
maintenance, a minimum clearance of
1.5 inches (3.8 cm) must be provided
from the combination temperature

Installing the water heater
Combustion and Ventilation Air
Proper operation of the water heater
requires air for combustion and ventilation.
Provisions for combustion and ventilation
air must comply with referenced codes and
standards.
DO NOT block or obstruct any of the
combustion air inlet openings located
around the perimeter of the water heater.
A minimum of 1 in. (2.54 cm) is required
between these combustion air inlet openings
and any obstruction.
NOTICE: If the water heater is installed
in an unconfined space within a building
of conventional frame, masonry or metal
construction, infiltration air is normally
adequate for proper combustion and
ventilation. If the water heater is installed in
a confined space, provisions for combustion
and ventilation air must be made.
DO NOT obstruct or block the Flammable
Vapor Sensor.
A confined space is one having a volume of
less than 50 cubic feet per 1,000 Btu/H (1.42
cubic meters per .29 kw) of the aggregate
input of all appliances within that space.
The air must be supplied through two
permanent openings of equal area. One is to
be located within 12 in. (30.5 cm) above the
floor and the other is to be located within 12
in. (30.5 cm) from the ceiling.
The minimum net free area of each opening
must not be less than one square inch (6.45
square cm) per 1,000 Btu/h of the total input
rating of all the appliances in the enclosure
[but not less than 100 square inches (6.45
square cm)], if each opening communicates
with other unconfined areas inside the
building.
Buildings of unusually tight construction
shall have the combustion and ventilation
air supplied from outdoors, or a freely
ventilated attic or crawl space.
If air is supplied from outdoors, directly or
through vertical ducts, there must be two
openings located as specified above and
each must have a minimum net free area of
not less than one square inch (6.45 square
cm) per 4,000 Btu/h (1.17 kw) of the total
input rating of all the appliances in the
enclosure.
If horizontal ducts are used to communicate
with the outdoors, each opening must have
a minimum net free area of not less than
one square inch (6.45 square cm) per 2,000
Btu/h (.58 kw) of the total input rating of
all the appliances in the enclosure. If ducts
are used, the minimum dimensions of
rectangular air ducts shall not be less than 3
in. (7.6 cm)
NOTICE: If the duct openings which
supply combustion and ventilation air are
to be covered with a protective screen or
grill, the net free area (openings in the
material) of the covering material must be
used in determining the size of the openings.
Protective screening for the openings MUST
NOT be smaller than 1/4 in. (.64 cm) mesh
to prevent clogging by lint or other debris.
Corrosive Atmospheres
The air in beauty shops, dry cleaning
establishments, photo processing
labs, and storage areas for liquid and
powdered bleaches or swimming pool
chemicals often contain such halogenated
hydrocarbons.
An air supply containing halogenated
hydrocarbons may be safe to breathe,
but when it passes through a gas flame
corrosive elements are released that
will shorten the life of any gas burning
appliance.
Propellants from common spray cans
or gas leaks from A/C and refrigeration
equipment are highly corrosive after
passing through a flame.
The water heater warranty is voided when
failure of the heater is due to operation in
a corrosive atmosphere.
NOTICE: The water heater
should not be installed near
an air supply containing
halogenated hydrocarbons.
9
Thermal Expansion
Determine if a check valve exists in the
inlet water line. Check with your local
water utility company. It may have been
installed in the cold water line as a separate
back flow preventer, or it may be part of
a pressure reducing valve, water meter or
water softener. A check valve located in
the cold water inlet line can cause what is
referred to as a “closed water system”. A
cold water inlet line with no check valve or
back flow prevention device is referred to as
an “open” water system.
As water is heated, it expands in volume and
creates an increase in the pressure within the
water system. This action is referred to as
“thermal expansion”. In an “open” water
system, expanding water which exceeds the
capacity of the water heater flows back into
the city main where the pressure is easily
dissipated.
A “closed water system”, however, prevents
the expanding water from flowing back
into the main supply line, and the result of
“thermal expansion” can create a rapid
and dangerous pressure increase in the
water heater and system piping. This rapid
pressure increase can quickly reach the
safety setting of the relief valve, causing
it to operate during each heating cycle.
Thermal expansion, and the resulting rapid,
and repeated expansion and contraction of
components in the water heater and piping
system can cause premature failure of the
relief valve, and possibly the heater itself.
Replacing the relief valve will not correct the
problem!
The suggested method of controlling thermal
expansion is to install an expansion tank
in the cold water line between the water
heater and the check valve (see illustration
below). The expansion tank is designed
with an air cushion built in that compresses
as the system pressure increases, thereby
relieving the over pressure condition and
eliminating the repeated operation of the
relief valve. Other methods of controlling
thermal expansion are also available.
Contact your installing contractor, water
supplier or plumbing inspector for additional
information regarding this subject.
Refer to the illustration below for suggested
typical installation. The installation of unions
or flexible connectors is recommended on
the hot and cold water connections so that
the water heater may be easily disconnected
for servicing if necessary. If flexible water
connections are used, the must comply with
the standard for flexible Water Connectors,
ASME A112.18.6/CSA-B125.6. The HOT
and COLD water connections are clearly
marked on the water heater. Install a shutoff
valve in the cold water line near the water
heater. Refer to the following illustration for
suggested typical installation.
Water Supply Connections
IMPORTANT: DO NOT
apply heat to the HOT or
COLD water connections. If
sweat connections are used,
sweat tubing to adapter
before fitting adapter to the
cold water connections on
heater. Any heat applied
to the cold water supply
fittings will permanently
damage the dip tube and
heat traps.
NOTICE: The National
Fuel Gas Code (NFGC)

Installing the water heater
A new combination temperature and pressure relief valve, complying with the Standard for Relief
Valves for Hot Water Supply Systems, ANSI Z21.22/CSA 4.4, is factory installed and must remain in
the opening provided and marked for the purpose on the water heater. No valve of any type should be
installed between the relief valve and the tank.
Relief Valve
The pressure rating of the relief valve
must not exceed 150 psi (1,034 kPa), the
maximum working pressure of the water
heater as marked on the rating plate.
The Btu/h rating of the relief valve must
equal or exceed the Btu/h input of the
water heater as marked on its rating plate.
Position the outlet of the relief valve above
a suitable open drain to eliminate potential
water damage. Piping used should be of a
type approved for hot water distribution.
The discharge line must be no smaller
than the outlet of the valve and must
pitch downward from the valve to allow
complete drainage (by gravity) of the relief
valve and discharge line.
The end of the discharge line should not
be threaded or concealed and should be
protected from freezing. No valve of
any type, restriction, or reducer coupling
should be installed in the discharge line.
To Fill the Water Heater
Make certain that the drain valve is closed,
then open the shut-off valve in the cold
water supply line.
Open each hot water faucet slowly to
allow the air to vent from the water heater
and piping.
A steady flow of water from the hot water
faucet(s) indicates a full water heater.
DO NOT allow the flammable vapor
sensor to become submerged in water.
WARNING: The tank
must be full of water before
heater is turned on. The
water heater warranty does
not cover damage or failure
resulting from operation
with an empty or partially
empty tank.
Condensation
Condensation can form on the tank
when it is first filled with water.
Condensation might also occur with a
heavy water draw and very cold inlet
water temperatures.
Drops of water falling on the burner can
produce a sizzling or pinging sound.
This condition is not unusual, and will
disappear after the water becomes heated.
If, however, the condensation continues,
examine the piping and fittings for
possible leaks.
11
WARNING: DO NOT attempt to convert this water heater for use with a different type of gas other than the
type shown on the rating plate. Such conversion could result in hazardous operating conditions.
Leak Testing
The water heater and its gas connections
must be leak tested at normal operating
pressures before it is placed in operation.
Turn on the manual gas shutoff valve
near the water heater.
Use a soapy water solution to test for
leaks at all connections and fittings.
Bubbles indicate a gas leak that must
be corrected.
The factory connections to the
combination gas control (thermostat)
should also be leak tested after the water
heater is placed in operation.
High Altitude
Input rating of this water heater is
based on sea level operation. At higher
elevations the actual input rate may be
lower than the value listed on the rating
label due to the derating of natural gas and
LP gas.
This water heater can be installed at
elevations up to 7,800 ft. (2,377 m) above
sea level.
IMPORTANT: Vent system lengths will
vary above 2,000 ft. (609 m). Contact the
water heater manufacturer for additional
information (see page 14).

The water heater and its individual
shutoff valve must be disconnected from
the gas supply piping system during any
pressure testing of that system at test
pressures in excess of 1/2 psi (3.5 kPa).
The water heater must be isolated from
the gas supply piping system by closing
its individual manual shutoff valve during
any pressure testing of the gas supply
piping system at test pressures equal to or
less than 1/2 psi (3.5 kPa).
Gas Supply
The branch gas supply line to the water
heater should be clean properly sized
steel pipe or other approved gas piping
material.
A union or ANSI design certified semi-
rigid or flexible gas appliance connector
should be installed in the gas line close to
the water heater. The National Fuel Gas
Code (NFGC) mandates a manual gas
shutoff valve: See (NFGC) for complete
instructions.
If flexible connectors are used, the
maximum length shall not exceed 36 in.
and must meet the requirements in ANSI
Z21.24/CSA 6.10 - Connectors for Gas
Appliances.
Compound used on the threaded joints of
the gas piping must be of the type resistant
to the action of LP gas. Use compound
sparingly on male threads only.
Where a sediment trap is not incorporated
as part of the appliance, a sediment trap
shall be installed downstream of the
equipment shutoff valve as close to the
inlet of the appliance as practical at the
time of the appliance installation. The
sediment trap shall be either a tee fitting
with a capped nipple in the bottom outlet
or other device recognized as an effective
sediment trap.
DO NOT use excessive force (over 31.5
ft lbs.) in tightening the pipe joint at the
combination gas control (thermostat) inlet,
particularly if teflon pipe compound is
used, as the valve body may be damaged.
The inlet gas pressure to the water heater
must not exceed 10.5 in. w.c. (2.6 kPa) for
natural gas, or 13 in. w.c. (3.2 kPa) for LP
gas.
For purposes of input adjustment, the
minimum inlet gas pressure (with main
burner on) is shown on the water heater
rating plate. If high or low gas pressures
are present, contact your gas supplier for
correction.
WARNING: Never use
an open flame to test for
gas leaks, as property
damage, personal injury, or
death could result.
WARNING: Failure to
install a water heater
suitable for the altitude at
the location it is intended to
serve, can result in improper
operation of the appliance
resulting in property
damage and/or producing
carbon monoxide gas, which
could result in personal
injury, or death.

Installing the water heater
Venting
NOTICE: This water heater may
installed in attics and garages provided
that the ambient temperatures do
not exceed 125° (52°C) and the
requirements as listed in the above table
are followed.
The support method used should isolate
the vent pipes from floor joists or other
structural members to help prevent the
transmission of noise and vibration.
DO NOT support, pin or otherwise secure
the vent system in a way that restricts the
normal thermal expansion and contraction
of the chosen venting material.
If the water heater is being installed as a
replacement for an existing power vent,
water heater, a thorough inspection of the
existing vent system must be performed
prior to any installation work.
Verify that the correct materials as
specified in this manual have been used,
and that the minimum or maximum
vent lengths and terminal location as
detailed in this manual have been met.
Carefully inspect the entire vent system
for any signs of cracks or fractures,
particularly at the joints between
elbows or other fittings and the straight
length of vent pipe.
DANGER: Failure to
install the blower assembly
if shipped detached from
the water heater and
properly vent the water
heater to the outdoors as
outlined in the Venting
section of this manual will
result in unsafe operation of
the water heater causing
bodily injury, explosion,
fire or death.
To avoid the risk of fire,
explosion, or asphyxiation
from carbon monoxide,
NEVER operate the water
heater unless it is properly
vented and has adequate air
supply for proper operation
as outlined in the Venting
section of this manual.
The vent pipe must overlap
a minimum of ½ in. on each
connection. It is important
that the vent pipe engages
fully into any pipe fitting
and be kept in that position
until the adhesive has fully
cured. DO NOT drill or
punch holes in the plastic
pipe or fittings.
NOTICE: This unit is
equipped with a Flammable
Vapor Sensor. DO NOT
apply power until enough
time has passed to allow the
vapors from the primer and
cement to dissipate.

the building is to be expected. However, improper location
or installation can result in severe damage to the structure
or exterior finish of the building
Vent
DO NOT install the vent terminal under any patio or deck.
To help prevent moisture from freezing on walls and under
eaves, DO NOT locate the vent terminal on the side of a
building with prevailing winter winds.
When terminating the vent and combustion air-inlet pipes
through brick or masonry surfaces, the installation of a rust
resistant sheet metal backing plates behind the vent and
combustion air-inlet terminals are recommended.
DO NOT locate the vent terminal too close to shrubbery, as
flue gasses may damage them.
Caulk all cracks, seams and joints within 6 ft. (1.83 m) of
the vent and combustion air-inlet terminals.
Insulate vent pipe exposed to cold conditions (attics, crawl
spaces, etc.) with inflammable material to help prevent
moisture from accumulating in the vent pipe.
Support horizontal sections of the vent and combustion
air-inlet pipe every 4 ft. (1.22 m). DO NOT rigidly secure
the vent system. Provisions must be made to allow for
expansion and contraction of the vent system.
DO NOT install the vent and combustion air-inlet terminals
less than 1 ft. (30 cm) above grade or average snowfall
whichever is greater.
Permanently seal annular openings around the vent and
combustion air-inlet system penetrations using approved
materials to prevent entry of combustion products into the

Condensate Management - Optional Piping
There is no condensate collection and disposal
required for Rheem water heaters under most
conditions. Installations where the vent system length
is short or where it runs through conditioned space
in the home, such as basements or interior walls,
DO NOT typically cause condensation and will not
require any condensation disposal methods regardless
of vent pipe slope. The image on page 17 shows the
recommended vent pipe slope of no less than 1/8 in.
per foot (10 mm per m) away from the water heater.
Any condensation in the venting system will drain
toward the vent termination. The blower assembly
features a capped drain port, which is not needed in
this case.
CAUTION: Make sure the drain port cap is
securely in place.
There are vent piping configurations, when combined
with certain environmental conditions that can
produce enough condensate to require collection
and disposal. When a slope away from the water
heater cannot be achieved and condensate handling
is required in a horizontal vent system, slope the vent
pipe toward the water heater 1/8 in. per foot (10 mm
per m) minimum and condensate management means
as follows:
• Using a set of pliers, remove the clamp and cap
from the drain port from the blower assembly.
• Connect the tubing with clamp to the condensate
drain port. Ensure that the clamp securely fastens
the tubing to the blower's condensate drain port.
NOTICE: The tubing must be of sufficient
length to reach a floor drain, outside the
building or other required condensate disposal
termination requirements (Refer to local codes).
• Loop the drain tube so that it has a circular trap
and secure the top and bottom of the loop with
wire ties or plastic zip ties as shown. DO NOT
restrict any portion of the drain tube. The loop
and all sections of the tube must not be restricted
or collapsed.
• Fill the drain tube with water so that no
combustion gases might vent into the room.
• Route the drain tube to a floor drain or outside
the building or refer to local codes for any
condensation requirements.

All joints in the vent piping must be
properly sealed and the following
materials are recommended:
PVC materials should use ASTM D2564
grade cement.
CPVC materials should use ASTM F493
grade cement.
ABS materials should use ASTM D2235
grade cement.
Cleaner-Primer and Medium Body
Solvent Cement:
Cut pipe end square, remove jagged
edges and burrs. Chamfer end of pipe,
then clean fitting socket and pipe joint
area of all dirt, grease or moisture.
After checking pipe and socket for
proper fit, wipe socket and pipe with
cleaner-primer. Apply a liberal coat of
primer to inside surface of socket and
outside of pipe. DO NOT allow primer
to dry before applying cement.
Apply a thin coat of cement evenly in
the socket. Quickly apply a heavy coat
of cement to the pipe end and insert
pipe into fitting with a slight twisting
motion until it bottoms out.
NOTICE: Cement must be fluid; if not,
recoat.
Hold the pipe fitting for 30 seconds to
prevent the tapered socket from pushing
the pipe out of the fitting.
Wipe all excess cement from the joint
with a rag. Allow 15 minutes before
handling. Cure time will vary according
to fit, temperature and humidity.
NOTICE: Stir the solvent cement
frequently while using. Use a natural
bristle brush or the dauber supplied
with the can. The proper brush size is
one inch.
NOTICE: This unit is equipped with
a Flammable Vapor Sensor. DO NOT
apply power until enough time has
passed to allow the vapors from the
primer and cement to dissipate.

For increased energy efficiency, some water
heaters have been supplied with two sections of
pipe insulation.
Please install the insulation, according to
the illustrations above, that best meets your
requirements.
Hot and Cold Pipe Insulation Installation
Insulation Blankets
Insulation blankets, available to the general
public, for external use on gas water heaters
are not necessary. The purpose of an insulation
blanket is to reduce the standby heat loss
encountered with storage tank heaters. This
water heater meets or exceeds the National
Appliance Energy Conservation Act standards
with respect to insulation and standby loss
requirements making an insulation blanket
unnecessary.
The manufacturer’s warranty does not cover
any damage or defect caused by installation,
attachment or use of any type of energy saving
or other unapproved devices (other than those
authorized by the manufacturer) into, onto or
in conjunction with the water heater. The use
of unauthorized energy saving devices may
shorten the life of the water heater and may
endanger life and property.
The manufacturer disclaims any responsibility
for such loss or injury resulting from the use of
such unauthorized devices.
CAUTION: If local codes require the
application of an external insulation blanket
to this water heater, pay careful attention to
the following so as not to restrict the proper
function and operation of the water heater:
DO NOT cover the operating or warning
labels attached to the water heater or attempt
to relocate them on the exterior of insulation
blanket.
DO NOT apply insulation to the top of the
water heater. This will interfere with the safe
operation of the blower assembly.
DO NOT cover the burner access door,
jacket door, combination gas control
(thermostat) or pressure and temperature
relief valve.
DO NOT apply insulation to the bottom
of the water heater or the area where
the combustion air inlet openings and
Flammable Vapor Sensor are located. This
area must be unobstructed so as not to
restrict combustion air flow to the burner or
operation of the sensor.
Inspect the insulation blanket frequently
making certain it has not sagged and it is
not restricting the air flow to the combustion
air inlet openings (perforation holes) or the
Flammable Vapor sensor located at the lower
perimeter of the water heater jacket. This
could result in an unsafe operating condition.
WARNING: If
local codes require
external application
of insulation
blanket kits the
manufacturer’s
instructions
included with the
kit must be
carefully followed.

FLAMMABLE!! To dissipate such gas and to reduce risk of injury, it is recommended that the hot water faucet be
opened for several minutes at the kitchen sink before using any electrical appliance connected to the hot water
system. If hydrogen is present, there will be an unusual sound such as air escaping through the pipe as the water
begins to flow. DO NOT smoke or use an open flame near the faucet at the time it is open.
!
DANGER: Hotter
water increases the
Potential for Hot
Water SCALDS.
Households with small
children, disabled, or
elderly persons may
require a 120°F (49°C)
or lower gas control
(thermostat) setting to
prevent contact with
HOT water.
Water Temperature Setting
The temperature of the water in the water
heater can be regulated by turning the
knob on the front of the combination gas
control (thermostat). Safety and energy
conservation are factors to be considered
when selecting the water temperature setting
of the water heater’s combination gas control
(thermostat(s). The lower the temperature
setting, the greater the savings in energy and
operating costs.
To comply with safety regulations, the
combination gas control (thermostat) was set
at 120°F (49°C) before the water heater was
shipped from the factory. The recommended
starting point temperature is 120°F (49°C).
Water temperatures above 125°F (52°C) can
cause severe burns or death from scalding. Be
sure to read and follow the warnings outlined
in this manual and on the label located on the
water heater near the gas control thermostat.
Mixing valves are recommended for reducing
point of use water temperature by mixing hot
and cold water in branch water lines. It is
recommended that a mixing valve complying
with the Standard for Temperature Actuated
Mixing Valves for Hot Water Distribution
Systems, ASSE 1017 be installed. See page
4 for more details and contact a licensed
plumber or the local plumbing authority for
further information.
The chart on the next page may be used
as a guide in determining the proper water
temperature for your home.
Operating Procedure
This heater is equipped with an electronically
lit pilot to light the main burner. The pilot is
automatically lit each time there is a demand
for heating the water. On initial start-up,
it is recommended that the outer door be
removed (leave inner door in place for safety)
to determine if the pilot and main burner are
operating properly.
Once filled with water, it is necessary to plug
the power cord in and slide the switch on the
combination gas control (thermostat) to the
"ON" position. The blower will start and within
seconds the pilot will light followed by the
main burner. After the main burner ignites,
replace the outer door.
If no main burner flame is established, the gas
control will go through three trials for ignition
before going into a lock-out. A warning light
will alert the user of this lock-out condition. If
this happens, refer to “Troubleshooting Guide.”
30
Operating the water heater
Maximum water temperatures occur just after
the burner has shut o. To determine the water
temperature, turn on a hot water faucet and place
a thermometer in the water stream.
If an adjustment to the water temperature is
preferred, then refer to the Water Heater User
Display – Operation Instructions for instruction
on adjusting the local and remote user display
temperature setpoints.
The reference mark "LOW" represents an ap-
proximate water temperature of 90°F (32°C).
The reference mark "HOT" represents an ap-
proximate water temperature of 120°F (49°C).
The reference mark "A" represents an approxi-
mate water temperature of 130°F (54°C).
The reference mark "B" represents an approxi-
mate water temperature of 140°F (60°C)
The reference mark "C" represents an approxi-
mate water temperature of 150°F (66°C)
The reference mark "VERY HOT" represents an
approximate water temperature of 160°F (71°C)
A condition known as “stacking” or “layering”
can occur when a series of short and frequent hot
water draws are taken.
The hottest temperature water will be at the top
of the tank, closest to the outlet pipe delivering
hot water to the home.
Stacking can cause this top layer of water to be
hotter than the water toward the bottom of the
tank near the combination gas control (thermo-
stat). Therefore, always remember to test the
water temperature with your hand before use and
remember that hotter water increases the risk of
scald injury.
Also, always supervise young children or others
who are incapacitated.
The combination gas control (thermostat) is
constructed with a built in safety shuto device
designed to shuto the gas supply to the burner
if the main burner is extinguished for any reason.
The combination gas control (thermostat) is also
equipped with a gas shut o device that will
shut o the gas supply to the burner if the water
heater exceeds normal operating temperatures.
Refer to the “Before You Call For Service” sec-
tion of this manual, or contact your dealer.
!
WARNING: Should overheating occur
or the gas supply fail to shut off, turn off
the manual gas (shutoff) valve to the
appliance
If the water heater has been subjected to re,
ood or physical damage, turn o the manual
gas control (shuto) valve and DO NOT operate
the water heater again until it has been checked
by a qualied service technician.

Sequence of Operation…
1. During initial start-up or a call for heat, the
control will verify the vacuum switch is
open.
2. Once the control verifies the blower
vacuum switch is open, the control will
energize the blower motor for the pre-purge
sequence (approximately 5 seconds).
3. The control will verify the blower vacuum
switch has closed, ensuring that the blower
is functioning properly and that the venting
system is not blocked.
4. The control will then proceed through
a sequence of self-diagnostics before
initiating a trial for ignition.
5. During the trial for ignition, the pilot will
spark in an attempt to light the pilot. Once
the pilot flame is established, the main gas
valve will open allowing gas to flow to the
main burner.
6. The main burner and pilot will remain lit
throughout the heat cycle until the water
temperature setting is reached.
7. Once the water temperature setting is
reached, the control will close the main gas
valve and pilot valve which will extinguish
both the main burner and pilot burner
flames.
8. The blower motor will stay energized
for an additional 30 seconds after the
control verifies that the burner flame is
extinguished in order to clear combustion
gases from the water heater.
9. After the post-purge sequence, the control
will de-energize the blower motor and go
into a stand-by mode awaiting the next call
for heat.
This water heater is equipped with a flammable
vapor sensor that is monitored continuously by
the electronic control in all modes of operation.
In the event that flammable vapors are detected,
the control will automatically shut down the
water heater and prevent the water heater from
being started again.
The following is a list of materials that will
cause the Flammable Vapor Sensor to shut down
the water heater.
Vapors of Gasoline.
Vapors of certain flammable paints, stains,
and thinners.
Vapors of vent pipe cement & solvents.
Bleach (direct contact with flammable vapors
sensor).
Some other flammable materials and their
vapors.
If the flammable vapor sensor shuts down the
water heater, then the electronic control will
display the appropriate error code and you
should then promptly contact a qualified service
technician.
Refer to the “WARNING” on page 3 for
additional information.
32
Care and cleaning of the water heater
Draining the Water Heater
!
CAUTION: Shut off gas to the
water heater at the gas control
(thermostat) gas cock or manual
shut-off valve before draining water.
!
DANGER: Before manually
operating the temperature and
pressure relief valve, make certain
no one will be exposed to the hot
water released by the valve. The
water drained from the tank may be
hot enough to present a scald
hazard and should be directed to a
suitable drain to prevent injury or
damage.
Before turning off the cold water supply to
the water heater, open a hot water faucet
allowing sufficient cold water into the
tank to prevent the risk of a scald injury
while draining the water heater. Once the
water in the tank is no longer hot, turn off
the cold water supply to the water heater.
Open a hot water faucet or lift the handle
on the relief valve to admit air to the tank.
Attach a garden hose to the drain valve on
the water heater and direct the stream of
water to a drain. Open the valve.
Routine Preventative Maintenance
Properly maintained, your water heater will
provide years of dependable trouble-free
service.
It is recommended that a periodic inspection
of the combination gas control (thermostat),
burner, relief valve, internal flue-way and
venting system should be made by service
personnel qualified in gas appliance repair.
It is suggested that a routine preventative
maintenance program be established and
followed by the user.
Periodically inspect the vent system. Make
certain that all joints are secure and that vent
pipe supports are all in place. Check the
outdoor vent terminal to see that it is free
of obstructions, and that there is no damage
nearby caused by condensate.
Inspect dilution air inlet and combustion air
inlet openings. Make certain no blockage
exists. Clean any lint, dirt or oil accumulation
that may exist.
Periodically clean the screens in the vent
terminal (if applicable).
Periodically, lift and release the lever handle
on the temperature pressure relief valve,
located near the top of the water heater,
to make certain the valve operates freely.
Allow few quarts to be drained through the
discharge line to an open drain.
NOTICE: If the temperature and
pressure relief valve on the water heater
discharges periodically, this may be due
to thermal expansion in a closed water
system. Contact the water supplier or your
plumbing contractor on how to correct
this.
DO NOT plug the relief valve outlet.
A water heater’s tank can act as a settling
basin for solids suspended in the water. It
is therefore not uncommon for hard water
deposits to accumulate in the bottom of
the tank. It is suggested that a few quarts
of water be drained from the water heater's
tank every month to clean the tank of these
deposits.
Rapid closing of faucets or solenoid valves
in automatic water using appliances can
cause a banging noise heard in a water pipe.
Strategically located risers in the water pipe
system or water hammer arresting devices
can be used to minimize the problem.
The anode rod should be removed from the
water heater’s tank annually for inspection
and replaced when more than 6 in.(15.2 cm)
of core wire is exposed at either end of the
rod.
Make sure the cold water supply is turned off
before removing anode rod.
This water heater incorporates a combustion
shut off device that shuts the operation of the
water heater down if undesirable combustion
conditions occur, such as the presence
of flammable vapors or blockage of the
combustion air inlet openings. Please contact
a Qualified Service Technician if this occurs.
DO NOT obstruct the flow of combustion
and ventilation air.
DANGER: Failure to perform the
recommended Routine Preventative
Maintenance can harm the proper
operation of this water heater, which can
cause carbon monoxide dangers, excessive
hot water temperatures and other
potentially hazardous conditions.
DANGER: Before
manually operating the
relief valve, make certain
no one will be exposed to
the danger of the hot water
released by the valve. The
water may be hot enough to
create a scald hazard. The
water should be released
into a suitable drain to
prevent injury or property
damage.
!
DANGER: Hotter water
increases the potential for
Hot Water Scalds.
Dilution Air Inlet

Housekeeping
Visually inspect the pilot.
Make sure that the combustion air inlet
openings located around the perimeter of the
water heater are not blocked or obstructed. A
minimum clearance of 1 in. (2.5 cm) is required
between the combustion air inlet openings and
any object.
DO NOT obstruct or block the Flammable
Vapor Sensor. The sensor does not require any
maintenance or cleaning.
DO NOT expose the flammable vapor sensor to
water, solvents or cleaning agents.
!
DANGER:
Keep appliance
area clear and free
from combustible
materials, gasoline
and other
flammable vapors
and liquids.
Burner Inspection
Visually inspect the pilot flame and main
burner periodically.
Through the sight glass, inspect the pilot
and burner lighting. If any unusual pilot
or burner operation is noted, the water
heater should be shut off until qualified
service assistance can be obtained.
!
CAUTION: For your safety,
cleaning of the burner must be
performed only by qualified service
personnel, as it involves the
disconnection of gas piping and leak
testing. The burner chamber is a sealed
area. If the burner access door is
removed, the burner access door gasket
must be replaced.
For cleaning, remove the burner from the
water heater. A vacuum cleaner can be
used on the burner and floor shield inside
the water heater. The burner can also be
cleaned by scrubbing with mild detergent.
Proper burner flame pattern
Venting System Inspection
Inspect the vent System. Make certain
that all joints are secure and vent system
supports are all in place. Check the
outdoor vent system terminal to see if it
is free of obstructions and that there is no
damage nearby caused by condensate.
Inspect dilution inlet. Make certain no
blockage exists. Clean any lint, dirt or oil
accumulation that may exist.
Test for spillage at the dilution air inlet
after 5 minutes of burner operation. Place
a blown out match or candle close to the
dilution are holes. The smoke from the
candle or match should be drawn into the
dilution air holes. If the smoke is pushed
away from the dilution air inlet, the
blower or vent system may be blocked.
Contact qualified service personnel.
Periodically clean the screens in the vent
terminal (if applicable).
In applicable climates, periodically inspect
the vent and air-inlet terminals to ensure
they are not blocked by snow.
Dilution Air Inlet
34
Vacation and Extended Shut-Down
If the water heater is to remain idle for an
extended period of time, the power and
water to the appliance should be turned off
to conserve energy and prevent a build-up
of dangerous hydrogen gas.
The water heater and piping should be
drained if they might be subjected to
freezing temperatures.
After a long shut-down period, the
water heater’s operation and controls
should be checked by qualified service
personnel. Make certain the water heater
is completely filled again before placing it
in operation.
NOTICE: Refer to the
Hydrogen Gas Caution in
the Operating Instructions.
Anode Rod
This water heater is equipped with an
anode rod designed to prolong the life
of the glass lined tank. The anode rod is
slowly consumed, thereby eliminating or
minimizing corrosion of the glass lined
tank.
Water sometimes contains a high sulfate
and/or mineral content and together with
cathodic protection process can produce
a hydrogen sulfide, or rotten egg odor in
the heated water. Chlorination of the water
supply should minimize the problem.
NOTICE: DO NOT
remove the anode rod
from the water heater’s
tank, except for inspection
and/or replacement, as
operation with the anode
rod removed will greatly
shorten the life of the glass
lined tank and will exclude
warranty coverage.
