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)
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.

SAFETY PRECAUTIONS
READ AND FOLLOW THIS SAFETY INFORMATION
CAREFULLY.
SAvE THESE INSTRUCTIONS
7
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 CAN/CSA B149 - Natural
Gas and Propane Installation Code. A copy can be purchased from the Canadian Standards
Association, 5060 Spectrum Way, Mississauga, Ontario L4W 5N6.
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.
When installed in a closet, DO NOT
block or obstruct any of the combustion
air inlet openings located around the
perimeter of the water heater. A
minimum of 1” (2.5 cm) is required
between these combustion air inlet
openings and any obstruction.
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 vapours are to be used or
stored. Such liquids include gasoline,
LP gas (butane or propane), paint or
adhesives and their thinners, solvents or
removers.
Because of natural air movement in a
room or other enclosed space, flammable
vapours can be carried some distance from
where liquids which give off flammable
vapours are to be used or stored. The open
flame of the water heater’s pilot or main
burner can ignite these vapours 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 must be
installed in accordance with the CAN/
CSA B149.1 - Natural Gas and Propane
Installation Code, for installation in
Residential Garages, unless otherwise
directed by Province 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.
● Minimum clearance from combustible
construction:
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 installed in an
alcove or closet, the entire floor must
be covered by a wood or metal panel.
A minimum of 24” clearance from the
front and top should be available for
adequate inspection and servicing.
● The water heater may be installed on com-
bustible floors, but not directly on carpet-
ing. If the water heater must be installed
on carpeting, place a metal or wood panel
beneath the water heater, extending beyond
its full width and depth at least 5” in all
directions.

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.
When installed in a closet, DO NOT block
or obstruct any of the combustion air inlet
openings located around the perimeter of
the water heater. A minimum of 1” (2.5 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.
A confined space is one having a volume
of less than 50 cubic feet (1.4 cubic
meters) 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” (30.5 cm)
above the floor and the other is to be
located within 12” (30.5 cm) from the
ceiling.
The minimum net free area of each opening
must not be less than one square inch
(6.5 sq cm) per 1000 Btuh of the total
input rating of all the appliances in the
enclosure, 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 (6.5 sq
cm) 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
(6.5 sq cm) 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” (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” (0.64 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.
Inspect Shipment
Inspect the water heater for possible
damage. Check the markings on the rating
plate of the water heater to be certain the
type of gas supplied corresponds to the
water heater requirements.
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.
Typical Installation
Refer to the illustration below for suggested typical installation. The installation of unions or
flexible copper connectors is 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 and are 3/4” NPT on all models. Install a shut-off valve in the cold
water line near the water heater.
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.
NOTICE: The
Canadian Standards
Association mandates
a manual gas shut off

Installing the water heater.
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 (1034 kPa), 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.
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.
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 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.
High Altitude
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.)
(2.6 kPa) for natural gas, or 1/2 psi (14”
w.c.) (3.5 kPa) for LP 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.)(2.6 kPa) for natural
gas, or 1/2 psi (14” w.c.) (3.5 kPa) for LP
gas.
Gas Supply
The branch gas supply line to the water
heater should be clean 1/2” black steel
pipe or other approved gas piping
material.
A ground joint 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
Canadian Standards Association mandates
a manual gas shut off valve: See CSA
B149- Installation Code 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.)(42.7 Nm) in tightening the pipe
joint at the 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” w.c. (2.65 kPa) for
natural gas, or 14” w.c. (3.5 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.
Ratings of gas appliances are based
on sea level operation and need not be
changed for installations at elevations
up to 5,999 feet (1,828 m).
!
WARNING: Installations above the
rated altitude as specified on the
altitude label 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
Installing the water heater.
The water heater must be installed with the factory supplied draft hood in place.
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 vent Tables in CAN/CSA B149
Natural Gas and Propane Installation Code.
Horizontal vent connectors must be pitched
upward to the chimney at least 1/4” per
foot (2.1 cm per meter) of length. Single
wall vent connectors must be at least 6” (15
cm) from adjacent unprotected combustible
surface. vent joints must be securely
fastened by sheet metal screws or other
approved method.
Models supplied with a 4” draft hood outlet
should have the draft hood secured by
inserting the screw provided into the hole
behind the leg that fits into the slot on top
of the water heater. The leg on the opposite
side should be secured with the screw
provided through the hole in the leg into the

opening(s).
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 CSA standards requirements
for energy efficiency, 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 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.
Inspect the insulation blanket frequently
making certain it has not sagged and is
restricting the air flow to the combustion
air inlet openings (perforation holes)
located around the lower perimeter of the
water heater jacket. This could result in
an unsafe operating condition.
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.
Heat Traps
For increased energy efficiency, some water
heaters have been supplied with factory
installed 3/4” NPT heat traps in the hot
outlet line and cold water inlet line.
These heat traps may require a minimum
of one (1) 90° 3/4” NPT elbow and may

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.
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.
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.
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 setting the
temperature dial on the front of the gas
control (thermostat).
Safety and energy conservation are factors
to be considered when selecting the water
temperature setting of the water heater’s
gas control (thermostat(s)). The lower the
temperature setting, the greater the savings
in energy and operating costs.
To comply with safety regulations, the 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°F).
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 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
information. (See page 4 for more details.)
The chart below may be used as a guide in
determining the proper water temperature
for your home.

Operating the water heater.
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.
The reference mark p on the rim of
the temperature dial, represents an
approximate water temperature of
120°F(49°C).
The reference
A
mark represents an
approximate water temperature of
130°F (54°C).
Each reference mark above or below these
points indicates an approximate change of
10°F (5.5°C).
To adjust the temperature, turn the
temperature dial to an initial setting of
120°F(49°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 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 gas control (thermostat) is constructed
with a built in safety shut-off device
designed to shut off the gas supply to the
burner if the pilot flame is extinguished
for any reason.
The 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 control valve to the appliance.
If the water heater has been subjected to
fire, flood or physical damage, turn off
the manual gas control (shut-off) valve,
and do not operate the water heater again
until it has been checked by qualified
personnel.
NOTICE: Replace any part of the gas
control system which has been under water.

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.
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.
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 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.
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 gas control
(thermostat) sensors, causing the sensors to
operate erratically. Because accumulated
solids can prevent the gas control
(thermostat) sensors from accurately
reading the water temperature, the water
at the fixture can be hotter than the gas
control (thermostat) dial setting. It is
suggested that a few liters 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”(15 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 vapours
or blockage of the combustion air inlet
openings. Please contact a qualified
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.
Housekeeping
vacuum around the base of the water
heater for dust, dirt and lint on a regular
basis. visually inspect pilot burner and
relight if necessary.
To ensure sufficient ventilation and
combustion air supply, proper clearances
must be maintained.
DO NOT block or obstruct any of the
combustion air inlet openings located
around the perimeter of the water heater. A
minimum of 1” (2.5 cm) is required between
these combustion air inlet openings and any
obstruction.
DANGER: Combustible
materials, such as clothing,
cleaning materials, or
flammable liquids, etc., must
not be placed against or next
to the water heater.
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

Venting System Inspection
The water heater’s internal flue must
be inspected annually to be certain it is
clean by removing the draft hood and flue
baffle.
When reinstalling the flue baffle make
certain it is hung securely by its hanger at
the top of the flue way.
Reinstall the draft hood.
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
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.
Burner Inspection
visually inspect the pilot burner and main
burner annually.
Through the site glass, inspect the pilot
burner flame 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. 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 and pilot burner
pattern.
Care and cleaning of the water heater.
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.
