IMPORTANT SAFETY INFORMATION.
READ ALL INSTRUCTIONS BEFORE USING.

DANGER!

LIQUEFIED PETROLEUM (LP)
AND NATURAL GAS MODELS

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.

● 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.

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.

● 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.

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 pan must not restrict air flow
to the combustion air inlet openings
(perforation openings) located around the
lower perimeter of the water heater.

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
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 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 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-inch stand in
accordance with the National Fuel Gas
Code, NFPA 54, ANSI Z223.1, 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

• The water heater should be installed

as close as practical to the gas vent or
chimney.

• Long hot water lines should be insulated

to conserve water and energy.

• The water heater and water lines should

be protected 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.

Inspect Shipment

Carefully inspect the water heater for
damage before proceeding with the
installation. Of specific interest should
be any dents or damage to the blower or
plenum assembly. If you find damage,

Combustion and Ventilation Air

DO NOT install or attempt any repair to
the water heater. Contact the manufacturer
as detailed under "IF YOU NEED
SERVICE" on page 32.

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.

When installed in a closet, DO NOT block
or obstruct any of the combustion air inlet
openings located around the perimeter of
the outer door. A minimum of 1” 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.

A confined space is one having a volume
of less than 50 cubic feet per 1000 Btuh
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” above the floor
and the other is to be located within 12”
from the ceiling.

The minimum net free area of each opening
must not be less than one square inch
per 1000 Btuh of the total input rating
of all the appliances in the enclosure

(but not less than 100 square inches), 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 per 4000
Btuh 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 per
2000 Btuh 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”.

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”mesh to prevent
clogging by lint or other debris.

NOTICE: The water heater
should not be installed near
an air supply containing
halogenated hydrocarbons.

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.

9

Installing the water heater.

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.

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 the heat traps
in the hot/cold nipples.

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.

Water Supply Connections

Refer to the illustration below for suggested
typical installation. The installation of unions

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, is supplied 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.

Relief Valve

The pressure rating of the relief valve
must not exceed 150 PSI, the maximum
working pressure of the water heater 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
protected from freezing. No valve of
any type, restriction, or reducer coupling
should be installed in the discharge line.

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.

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.

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

!

Installing the water heater.

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
black steel pipe or other approved gas
piping material.

A union or ANSI design certified semi­rigid 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
shut-off valve: See (NFGC) for complete
instructions.

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 14” w.c. for natural 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.

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 gas
control (thermostat) should also be leak
tested after the water heater is placed in
operation.

Pressure Testing the Gas Supply System

The water heater and its manual gas
shut-off valve must be disconnected from
the gas supply piping system during any
pressure testing of that system at
pressures in excess of 3/8 psi (10.5” w.c.)
for natural gas.

The water heater must be isolated from
the gas piping system by closing the
manual gas shut-off valve during any
pressure testing of the gas supply piping
at pressures equal to or less than
3/8 psi (10.5” w.c.) for natural gas.

High Altitude

This water heater is certified for
installations up to 8,500 feet above sea
level.

WARNING: Installations above 8,500
feet are not authorized and may result in
improper and inefficient operation of the
appliance, producing carbon monoxide gas
in excess of acceptable limits, which could
result in serious injury or death.

12

The water heater must be installed with the factory supplied draft hood in place.

DANGER: Failure to
install the draft hood 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.

WARNING: If local codes
require external application
of insulation blanket kits
the manufacturer’s
instructions included with
the kit must be carefully
followed.

Venting

Vent connectors must be attached to the
draft hood outlet to connect the water
heater to the gas vent or chimney. The vent
connectors must be the same size (diameter)
as the draft hood or larger, never smaller.

For proper venting in certain installations a
larger vent connector size may be needed.
Consult the latest version of the National
Fuel Gas Code (ANSI Z223.1/NFPA 54).

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.

Horizontal vent connectors must be pitched
upward to the chimney at least 1/4” per foot
of length. Single wall vent connectors must
be at least 6” from adjacent unprotected
combustible surface. Vent joints must be
securely fastened by sheet metal screws or
other approved method.

Test for spillage at the draft hood relief
opening after 5 minutes of main burner
operation. Use a flame of a match or
candle or smoke. The flame or smoke
should be pulled into the draft hood’s relief
opening(s).

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 draft hood.

 DO NOT cover the burner access door,

jacket door, gas control (thermostat)/gas

valve 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 are located.

This area must be unobstructed so as

not to restrict combustion air flow to the

burner.

 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

making certain it has not sagged and is

restricting the air flow to the combustion

air inlet openings located around the

perimeter of the water heater outer door.

This could result in an unsafe operating

condition.

13

Installing the water heater.

Wiring

This water heater may be connected
to electric service with the power cord
provided (DO NOT use an extension cord).
A grounding receptacle is required.

If local codes do not permit the use of cord
connections, a 120 V, 50/60 Hz power
supply, with suitable disconnecting means,
must be connected to the black and white
leads in the blower assembly.

The maximum current draw is less than 5.0
amps.

Operating the Water Heater

!

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.

Safety Precautions

DO turn off manual gas shut-off valve if water heater

has been subjected to over heating, fire, flood,
physical damage or if the gas supply fails
to shut off.

DO NOT turn on water heater unless it is completely

filled with water.

DO NOT turn on water heater if cold water supply

shut-off valve is closed.

DO NOT allow combustible materials such as

newspaper, rags or mops to accumulate near
water heater.

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 start­up, 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 necessary 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

DO NOT store or use gasoline or other flammable

vapours 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 vapours
lighting.

NOTICE: Flammable vapours 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.

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 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.”

Sequence of Operation

During initial start-up or a call for heat, the
control will verify the vent vacuum switch is
open.

Once the control verifies the vent vacuum switch
is open, the control will energize the blower
motor for the pre-purge sequence (approximately
5 seconds).

The control will verify the vent vacuum
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 ignition.

During the trial for ignition, the hot surface
ignitor 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
vapour sensor that is monitored continuously by
the electronic control in all modes of operation.

In the event that flammable vapours 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 Vapour Sensor to shut
down the water heater.

 Vapours of Gasoline.

 Vapours of certain flammable paints, stains,

and thinners.

 Vapours of vent pipe Cement & Solvents.

 Bleach (direct contact with flammable vapour

sensor).

 Some other flammable materials and their

vapours.

If the flammable vapour 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 “NOTICE” on page 3 for additional
information.

Draining the Water Heater

CAUTION: Shut off gas to the water
heater at the gas control (thermostat)
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.

In order to drain the water heater, turn off
the cold water supply. 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.

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.

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.

Routine Preventative Maintenance

Properly maintained, your water heater
will provide years of dependable trouble­free service.

It is recommended that a periodic
inspection of the 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.

PRESSURE SWITCH - Inspect the inlet

to the pressure switch and the tubing for
debris or blockage. Clean out the tubing
periodically to prevent buildup of debris.

At least once a year, 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 several gallons to
flush through the discharge line to an open
drain.

NOTICE: If the temperature and
pressure relief valve on the hot 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. 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
combination gas control (thermostat)
sensors from accurately reading the water
temperature, 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 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” 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.

DANGER: Combustible
materials, such as clothing,
cleaning materials, or
flammable liquids, etc., must
not be placed against or next
to the water heater.

Housekeeping

Visually inspect the hot surface ignitor.

Make sure that the flammable vapor
sensor is not blocked or obstructed.

To ensure sufficient ventilation and
combustion air supply, proper clearances
must be maintained.

DO NOT expose the flammable vapor
sensor to water, solvents, or cleaning
agents.

Venting System Inspection

Inspect the gas venting system and the
chimney.

Make certain the vent connector from
the draft hood to the chimney is properly
positioned and securely attached.

If after inspection of the vent system
you found soot or deterioration;
call the local gas utility to correct the

Burner Inspection

problem and clean the flue, or replace
the flue, flue baffle, and venting system
before resuming operation of the water
heater.

Test for spillage at the draft hood relief
opening after 5 minutes of burner
operation. Use a flame of a match or
candle or smoke.

NOTICE: Refer to the
Hydrogen Gas Caution in the
Operating Instructions.

Through the sight glass, visually inspect
the hot surface ignitor and main burner
periodically.

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 inner door gasket must be
replaced.

For cleaning, remove the inner doors
burner assembly from the water heater. A
vacuum cleaner can be used on the burner
and inside the water heater. The burner
can also be cleaned by blowing air over
the burner surface. Do not allow any
large debris to remain inside the burner.

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: 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.

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.

Blower

DANGER: Disconnect power to

blower before cleaning.

Clean the blower periodically to remove
any buildup of lint or dirt. Remove the

24

inlet plate and blow out any lint or dirt on
the wheel and on the screen of the inlet
plate. Before operation, re-install the inlet
plate to the blower.
