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
l 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.
l 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.
l 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.
l 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.
l 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.
l 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.
l 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:
l Do not attempt to find the cause yourself.
l Do not try to light any appliance.
l Do not touch any electrical switch.
l Do not use any phone in your building.
l Leave the house immediately and make
sure your family and pets leave also.
l Leave the doors open for ventilation
and contact the gas supplier, a qualified
service agency or the fire department.
l 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.

IMPORTANT SAFETY INFORMATION.
READ ALL INSTRUCTIONS BEFORE USING
!
WARNING!
For your safety, the information in this manual must be followed to minimize the risk of
fire or explosion, electric shock, or to prevent property damage, personal injury, or loss of
life.
FOR INSTALLATIONS IN THE STATE OF CALIFORNIA
California Law requires that residential water heaters must be braced, anchored or
strapped to resist falling or horizontal displacement due to earthquake motions. For
residential water heaters up to 52-gallon capacity, a brochure with generic earthquake
bracing instructions can be obtained from: Office of the State Architect, 1102 Q Street,
Suite 5100, Sacramento, CA 95814 or you may call 916-445-8100 or ask a water heater
dealer.
However, applicable local codes shall govern installation. For residential water heaters
of a capacity greater than 52 gallons, consult the local building jurisdiction for acceptable
bracing procedures.
Have the installer show you the location of the gas shut-off valve and how to shut it off
if necessary. Turn off the manual shut-off valve if the water heater has been subjected to
overheating, fire, flood, physical damage or if the gas supply fails to shut off.
l Read this manual entirely before installing
or operating the water heater.
l Use this appliance only for its intended
purpose as described in this Use and Care
Manual.
l Be sure your appliance is properly installed
in accordance with local codes and the
provided installation instructions.
l DO NOT attempt to repair or replace
any part of your water heater unless it is
specifically recommended in this manual.
All other servicing should be referred to a
qualified technician.
SAFETY PRECAUTIONS
READ AND FOLLOW THIS SAFETY INFORMATION
CAREFULLY.
SAVE THESE INSTRUCTIONS
IMPORTANT
Carefully inspect the water heater for damage before proceeding with the installation. Of specific
interest should be any dents in the long blue cover panel for the combustion air-inlet, PVC pipe; or
damages to the blower and the combustion air-inlet, PVC pipe assembly. If you find damage, DO

WARNING: Combustible
construction refers to
adjacent walls and ceilings
and should not be confused
with combustible or
flammable products and
materials. Combustible
and/or flammable products
and materials should never
be stored in the vicinity of
this or any gas appliance.
Notice: DO NOT allow the
flammable vapor sensor to
become submerged in water.
Make sure the catch pan is
properly drained.
Flammable
Vapor
Sensor
Notice: DO NOT allow the
catch pan to obstuct the
flammable vapor sensor.
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 catch pan,
adequately drained, must be installed
under the water heater.
The water heater must be centered in the
catch pan.
Catch 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 sufficient-
ly support the weight of the water heater
once it is filled with water.
This gas-fired water heater or any other
appliance should not be installed in a
space where liquids which give off flam-
mable vapors are to be used or stored.
Such liquids include gasoline, LP gas
(butane or propane), paint or adhesives,
thinners, solvents and/or combustible
removers.
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 main burner
can ignite these vapors creating a shut
down condition which will not allow the
water heater to ignite.
Rheem Water Heating FVIR certified gas
water heaters can be installed on a residen-
tial garage floor without the use of an 18
in. (46 cm.) stand in accordance with the
National Fuel Gas Code, ANSI Z223.1/
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.
● We recommend this water heater be
installed in locations where the ambient
temperatures do not exceed 100°F
(38°C).
IMPORTANT: 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
and combustion air-inlet pipe and the
number of vent and combustion air-inlet
connection fittings required.
● See Vent and Combustion Air-Inlet
Section for vent system requirements.
● 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 this water heater out-
doors.

● 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.
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 “ther-
mal 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, caus-
ing it to operate during each heating cycle.
Thermal expansion, and the resulting rapid, and
repeated expansion and contraction of compo-
nents 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 on page 9). 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.

Installing the Water Heater
Corrosive Atmospheres
The air in beauty shops, dry cleaning establish-
ments, photo processing labs, and storage areas
for liquid and powdered bleaches or swim-
ming pool chemicals often contain halogenated
hydrocarbons.
An air supply containing halogenated hydro-
carbons 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 fail-
ure of the heater is due to operation in a corro-
sive atmosphere.
NOTICE: The
water heater must
not be installed
near an air supply
containing halogenated
hydrocarbons.
Refer to the following illustration for suggested
typical installation. The installation of unions
or flexible copper connectors are recommended
on the hot and cold water connections so that
the water heater may be easily disconnected for
servicing if necessary. 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.
IMPORTANT
For models equipped with a Top Cap, it is rec-
ommended that the hot and cold water piping
have a minimum vertical height of 10 inches
(25.4 cm) from the top of the water heater
before transitioning into any elbow. This verti-
cal height is needed in order to provide adequate
clearance for Top Cap installation and removal.
To gain access to the hot and cold water con-
nections on models equipped with a Top Cap,
remove the two (2) screws that secure the top
cap to the water heater then pull the Top Cap
upward and off the water heater. See illustra-
tion of Top Cap and screws on pages 31 & 43.
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)
mandates a manual
gas shut-off valve: See
(NFGC) for complete
instructions. Local codes
or plumbing authority
requirements may vary
from the instructions or
diagrams provided and
take precedent over these
instructions.
A new combination temperature and pressure relief valve, complying with the Standard for Relief Valves
and Automatic Gas Shut-Off Devices 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. Local codes shall govern the
installation of relief valves.

as marked on the rating plate.
The Btuh rating of the relief valve must
equal or exceed the Btuh 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 pro-
tected from freezing. No valve of any type,
restriction, or reducer coupling must be
installed in the discharge line.

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.
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. (91.4 cm) 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 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.
(42.7 N●m) in tightening the pipe joint at the
combination gas control 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 14.0 in. w.c. (3.5 kPa) w.c. for natu-
ral gas, or 14.0 in. w.c. (3.5 kPa) w.c. for LP
gas. For purposes of input adjustment, the mini-
mum 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.
10
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 all 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 the water 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 also 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 siz-
zling or pinging sound. This condition is not
unusual, and will disappear after the water
becomes heated. However, if condensation
continues, examine the piping and fittings for
possible leaks.
Installing the Water Heater
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 shut-off 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 should also be leak tested after the water
heater is placed in operation.
WARNING: Never use
an open flame to test for
gas leaks, as property
damage, personal injury,
or death could result.
High Altitude
Pressure Testing the Gas Supply System
The water heater and its individual shut-off
valve must be disconnected from the gas
supply piping system during any pressure
testing of that system at test pressures in
excess 1/2 psi (3.5 kPa).
The water heater must be isolated from the
gas supply piping system by closing its
individual manual gas shutoff valve during
any pressure testing of the gas supply at
test pressures equal to or less than 1/2 psi
(3.5 kPa).

Vent and Combustion Air-Inlet
This water heater is a direct vent appli-
ance and must be installed so that all air
for combustion is derived directly from the
outside atmosphere and all flue gases are
discharged to the outside atmosphere. For
proper installation of the vent and combus-
tion air-inlet systems, follow the instruc-
tions as detailed in this manual. DO NOT
connect this water heater to an existing vent
or chimney - it must be vented separately
from all other appliances.
NOTICE: This water heater is approved
to use the following materials for pipe
of the vent and combustion air-inlet sys-
tems:
PVC (Schedule 40, Cellular Core,
ASTM-F891)
PVC (DWV, ASTM-D2665 or
CSA B181.2)
PVC (Schedule 40, ASTM-D1785 or
CSA B137.3)
PVC (SDR Series, ASTM-D2241 or
CSA B137.3)
CPVC (CPVC 4120, ASTM-D2846 or
CSA B137.6)
CPVC (Schedule 40, ASTM-F441 or
CSA B137.3)
CPVC (SDR Series, ASTM-F442)
ABS (Schedule 40, DWV, ASTM-D2661 or
CSA B181.1)
ABS (Schedule 40, DWV, Cellular Core,
ASTM-F628)
This water heater is approved to use the
following materials for the fittings of the
vent and combustion air-intake systems:
PVC (Schedule 40 DWV, ASTM D2665)
CPVC (Schedule 40, ASTM F438)
ABS (Schedule 40 DWV, ASTM D2661)
DO NOT mix ABS pipe and fittings with
PVC or CPVC pipe fittings. Note: It
is acceptable to interchange PVC and
CPVC pipe and fittings.
Vent and combustion air-inlet systems must
be adequately supported along both vertical
and horizontal lengths.
The vent and combustion air-inlet sys-
tems of this water heater may be installed
horizontally through a wall or vertically
through the roof.
Maximum unsupported length is recom-
mended to be no more than 4 feet (1.22 m).
It is imperative that the first hanger be
located on the horizontal length immedi-
ately adjacent to the first 90-degree elbow
from the vertical rise of vent pipe connect-
ed to the water heater.
DANGER: Failure to
properly install the vent
and combustion air-inlet
systems as outlined in the
Vent and Combustion Air-
Inlet 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 the
vent and combustion air-
inlet systems are properly
installed as detailed in the
"Vent and Combustion
Air-Inlet" section of this
manual.
The vent and combustion
air inlet pipes must
overlap a minimum of 1/2
in. (1.3 cm) at each joint.
It is important that the
vent and combustion air-
inlet pipes engage 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.
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. For
Power Direct Vent models listed in the
venting tables that do not show venting
configurations above 7,700 ft. (2,347 m),
contact the water heater manufacturer for a
required High Altitude Kit that will allow
the specific water heater model to operate
at altitudes between 7,700 ft. (2,347 m) and
10,200 ft. (3,109 m). See page 44.
!
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.
12
The support method used should isolate the vent
and combustion air-inlet 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
and combustion air-inlet systems in a way that
restricts the normal thermal expansion and con-
traction of the chosen venting material.
If the water heater is being installed as a
replacement for an existing power direct vent
water heater, a thorough inspection of the exist-
ing vent and combustion air-inlet systems must
be performed prior to any installation work.
Verify that the correct materials as speci-
fied in this manual have been used, and
that the minimum or maximum vent and
combustion air-inlet lengths and terminal
locations as detailed in this manual have
been met.
Carefully inspect the entire vent and com-
bustion air-inlet systems for any signs of
cracks or fractures, particularly at the joints
between elbows or other fittings and the
straight length of vent pipe.
Check the vent and combustion air-inlet for
signs of sagging or other stresses in the
joints as a result of misalignment of any
components in the systems.
If any of the conditions above are found,
they must be corrected in accordance with
the instructions in this manual before com-
pleting the installation and putting the
water heater into service.
Read these instructions thoroughly and make
sure you understand all steps and procedures
before proceeding with the installation.
1. Connect the vent system piping to the
blower assembly using the already installed
2 in. (5.1 cm) diameter rubber coupling and
clamps.
2. Connect the combustion air-inlet system
piping to the combustion air-inlet piping tee
using the 2 in. (5.1 cm) already installed
rubber coupling and clamps (See Figure 1).
3. For vent and combustion air-inlet terminals,
use the two (2), 2 in. (5.1 cm) diameter,
Schedule 40, PVC, 90°, 1/4 standard bend
elbows supplied with the water heater.

Installing the Water Heater
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
building.
If soffit vent is too close,
block off and install new vent
at another location

WARNING: Moisture in the flue gas will condense as it
leaves the vent terminal. In cold weather this condensate can
freeze on the exterior wall, under the eaves and on
surrounding objects. Some discoloration to the exterior of
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
19
Read these instructions thoroughly and make
sure you understand all steps and procedures
before proceeding with the installation.
Determine the locations for the vent and com-
bustion air-inlet terminals then make two (2)
holes through the exterior wall to accommodate
the vent and combustion air-inlet pipes.
• Maintain a minimum horizontal distance of
12 in. (30.5 cm) between the vent and com-
bustion air- inlet terminal centerlines.
Insert lengths of vent and combustion air-inlet
pipes through the wall as shown.
• Allow sufficient length of pipe to extend
beyond the exterior wall of the building for
attachment of the vent and combustion air-
inlet terminals.
Place the supplied 1/2 in. (1.3 cm) mesh metal
screens inside each terminal fitting.
NOTICE: For cold climates the screens may

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 20
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 pipe coupling 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:
• Remove the cap from vent pipe coupling, drain port
on the blower assembly.
• Connect 1/2 in. I.D, flexible, PVC (or equivalent
material), clear tubing to the 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 collasped.
• 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..
Installing the Water Heater
All joints in the vent piping must be properly
sealed and the following materials are recom-
mended:
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-prim-
er. 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 pre-
vent 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.
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.
Cementing Joints
WARNING: DANGER OF
FIRE OR BODILY INJURY -
Solvent cements and primers
are highly flammable. Provide
adequate ventilation and do
not assemble near heat source
or open flame. Do not smoke.
Avoid skin or eye contact.
Observe all cautions and
warnings on material
containers.

lumpy or thickened.
DO NOT thin solvent cement.
Observe shelf precautions
printed on the containers.
For applications below 32°F
(0°C) use only low temperature
type solvent cement.
Appropriate solvent and
cleaner must be used for the
type of pipe used (PVC, CPVC
or ABS).

For increased energy efficiency, some water
heaters have been supplied with two 24 in.
(61 cm) long sections of pipe insulation.
Please install the insulation, according to
the illustrations above, that best meets your
requirements.
Typical vertical piping arrangement
Hot and Cold Pipe Insulation Installation
Insulation Blankets
Insulation blankets, available to the general pub-
lic, 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 insu-
lation 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, gas control (thermostat) or pressure and
temperature relief valve.
DO NOT apply insulation to the area where
the Flammable Vapor Sensor is located. This
area must be unobstructed so as not to restrict
air flow to the sensor.
Inspect the insulation blanket frequently mak-
ing certain it has not sagged and it is not restrict-
ing the air flow to the Flammable Vapor sensor
located around 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.

Do Not allow combustible materials such as newspa-
per, rags or mops to accumulate near
water heater.
Do Not store or use gasoline or other flammable
vapors and liquids, such as adhesives or paint thinner,
in vicinity of this or any other appliance.
If such flammables must be used, open doors
and windows for ventilation, and all gas burning
appliances in the vicinity should be shut off including
their pilot burners, to avoid vapors lighting.
NOTICE: Flammable vapors can be drawn by air
currents from surrounding areas to the water heater.
If there is any difficulty in understanding or following
the Operating Instructions or the Care and Cleaning
section, it is recommended that a qualified person or
serviceman perform the work.
CAUTION: Hydrogen gas can be produced in a hot water system served by this water heater that has not been
used for a long period of time (generally two weeks or more). HYDROGEN GAS IS EXTREMELY
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

for Hot Water SCALDS
.
Households with small
children, disabled, or elderly
persons may require a 120°F
(49°C) or lower combination
gas control (thermostat)
setting to prevent contact
with unsafe water
temperatures.
Water Temperature Setting
The temperature of the water in the water
heater can be regulated by pressing the
buttons 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). 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 its lowest setting 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 combination gas control (thermostat).
Mixing valves are available for reducing
point of use water temperature by mixing
hot and cold water in branch water lines.
Contact a licensed plumber or the local
plumbing authority for further informa-
tion.
The chart on the next page may be used
as a guide in determining the appropriate
water temperature for your home.
Operating Procedure
This water heater is equipped with a hot
surface ignitor to light the main burner.
There is no pilot light to be lit, but on initial
start-up, it is recommended that the outer
door be removed (leave inner door in place
for safety) to view through the sight glass if
the hot surface ignitor and main burner are
operating properly.
Once filled with water, it is only neces-
sary to plug the power cord in and make
sure the “ON/OFF” switch located on the
blower assembly is in the “ON” position to
put the water heater into operation. Within
seconds the hot surface ignitor should heat
up, then the gas valve should open and the
main burner ignite. After the main burner
ignites, replace the outer door. If no main
burner flame is established, the combina-
tion 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.”
TO SHUT OFF WATER HEATER – Turn
switch located on the side of the blower
assembly to the “OFF” position. See dia-
gram on page 43 for location of blower
assembly.
35
Water Temperature Setting…
Maximum water temperatures occur just
after the burner has shut off. To determine
the water temperature, turn on a hot water
faucet and place a thermometer in the water
stream.
To avoid any unintentional changes in water
temperature settings, the combination gas
control (thermostat) has a tamper resistant
feature for changing the temperature setting.
To change the temperature setting follow
these instructions.
1. "Wake Up" the temperature indicators
by holding down both "COOLER" and
"HOTTER" temperature adjustment
buttons at the same time for one second,
see Figure below. One or two of the
temperature indicators will light up.
These indicators will only remain on
for 30 seconds if no further buttons are
pressed. After 30 seconds the control will
go back to "sleep" mode.
2. Release both of the temperature buttons.
a. To decrease the temperature press and
release the "COOLER" button until
the desired setting is reached.
b. To increase the temperature press and
release the "HOTTER" button until
the desired setting is reached.
NOTICE: Holding down the button
will not continue to lower or raise the
temperature setting. The button must be
pressed and released for each temperature
change desired.
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
(thermostat). 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 shutoff
device designed to shut off 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 single use gas shut off
device that will shut off the gas supply to the
burner if the water heater exceeds normal
operating temperatures. Refer to the Before
You Call For Service section 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 fire,
flood or physical damage, turn off the manu-
al gas (shutoff) valve, and do not operate the
water heater again until is has been checked
by a qualified service technician.

Operating the Water Heater
36
Sequence of Operation
During initial start-up or a call for heat, the con-
trol will verify the vacuum switch is open.
Once the control verifies the vent pressure switch
is open, the control will energize the blower
motor for the pre-purge sequence (approximately
5 seconds).
The control will verify that the vent pressure
switch has closed, ensuring that the blower is
functioning properly and that the venting system
is not blocked.
The control will then proceed through a sequence
of self-diagnostics before initiating a trial for igni-
tion.
During the trial for ignition, the hot surface ignit-
or will warm up.
Once the hot surface ignitor warms up, the main
gas valve will open allowing gas to flow to the
main burner.
Once the main burner ignites, the control will
verify that the burner flame is present through the
flame sense circuit. The hot surface ignitor will
then turn off.
The main burner will remain lit throughout the
heat cycle until the water temperature setting is
reached.
Once the water temperature setting is reached, the
control will close the main gas valve which will
extinguish the main burner flames.
The blower motor will stay energized for an
additional 5 seconds after the control verifies that
the burner flame is extinguished in order to clear
combustion gases from the water heater.
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 vapor
sensor).
Some other flammable materials and their
vapors.
If the flammable vapor sensor shuts down the
water heater, then the electronic control will dis-
play the appropriate error code and you should
then promptly contact a qualified service techni-
cian.
Refer to the “NOTICE” on page 3 for additional
information.
37
Care and Cleaning of the Water Heater
Draining the Water Heater
!
CAUTION: Shut off gas to the
water heater at the manual gas 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 inspec-
tion of the combination gas control
(thermostat), burner, relief valve, internal
flue-way, vent and combustion air-inlet
systems 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.
Inspect the combustion air-inlet and vent
systems. Make certain that all joints are
secure and that combustion air-inlet and
vent pipe supports are all in place. Check
the outdoor combustion air-inlet and
vent terminals to see that they are free of
obstructions, and that there is no damage
nearby caused by condensate.
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 oper-
ates freely. Allow several gallons to flush
through the discharge line to an open
drain.
NOTICE: If the temperature and pres-
sure relief valve on the water heater
discharges periodically, this may be
due to thermal expansion in a closed
water system. Contact the water sup-
plier 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. If allowed to accumulate, these
solids can cover the combination gas
control (thermostat) sensors, causing the
sensors to operate erratically. Because
accumulated solids can prevent the com-
bination gas control (thermostat) sensors
from accurately reading the water tem-
perature, the water at the fixture can be
hotter than the combination gas control
(thermostat) setting. 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 appli-
ances 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 periodically, 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 combus-
tion shut off device that shuts the opera-
tion of the water heater down if undesir-
able combustion conditions occur, such
as the presence of flammable vapors or
blockage of the combustion air-inlet and/
or vent systems. Please contact a quali-
fied service technician if this occurs.
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: 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: Hotter
water increases the
potential for Hot Water
Scalds.
38
Housekeeping
Make sure the Flammable Vapor Sensor is
not blocked or obstructed.
DO NOT expose the Flammable Vapor
Sensor to water, solvents or cleaning
agents.
!
DANGER: Combustible
materials, such as clothing,
cleaning materials, or
flammable liquids, etc., must
not be placed against or next
to the water heater.
Burner Inspection
Visually inspect the hot surface ignitor and
main burner periodically.
Through the sight glass, inspect the hot
surface ignitor with the main burner off
and inspect the main burner while firing.
If any unusual 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.

Combustion Air-Inlet and Vent System Inspection
Inspect the combustion air-inlet and vent
systems. Make certain that all joints are
secure and that combustion air-inlet and
vent system supports are all in place. Check
the outdoor combustion air-inlet and vent
system terminals to see that they are free of
obstructions, and that there is no damage
nearby caused by condensate.
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 freez-
ing temperatures.
After a long shut-down period, the water
heater’s operation and controls should
be checked by qualified service person-
nel. 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 slow-
ly consumed, thereby eliminating or mini-
mizing 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.
