Installation
1. INSPECT SHIPMENT—Inspect water heater for possible shipping
damage. Check the marking of the rating plate of the water heater to be
certain the type of gas being furnished corresponds to that for which the
water heater is equipped.
! WARNING
The Btu/hr Rating of the relief valve must not be less than the
input rating of the water heater as indicated on the rating label located on front of the heater (1 watt = 3.412 BTU/HR).
2. THERMAL EXPANSION — During installation, a check valve should
have been installed in the inlet water line. 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.
! WARNING
Connect the outlet of the relief valve to a suitable open drain so
that the discharge water cannot contact live electrical parts and
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.
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!
5. TO FILL WATER HEATER — Make certain drain valve is completely closed. Open shut-off valve in cold water supply line. Open
each hot water faucet slowly to allow 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
Tank MUST BE full of water before pilot is lit. The water heater’s
warranty does not cover damage or failure resulting from
operation with an empty or partially empty tank.
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. (Refer to Figure 3.) 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 vale. Other methods of controlling thermal
expansion are also available. Contact your installing contractor, water
supplier, or plumbing inspector for additional information regarding this
subject.
6. GAS SUPPLY - The branch gas supply line to the water heater should be clean
13 mm (1/2 inch) black steel pipe or other approved gas piping material.
A ground joint union or equivalent national standard design certified
semirigid or flexible gas appliance connector should be installed in gas
line closest to the water heater, and a manual gas shut-off valve should
be installed in the gas line prior to the union. The manual gas shut-off
valve should be at least 1.5 meters (5 feet) above the floor and readily
accessible for turning on or off. A sediment trap should be installed at
the bottom of the gas line. (Ref. to Fig. 3)
3. WATER SUPPLY CONNECTIONS — Refer to Fig. 3 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.
Compound used on 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. Do not use excessive force over
42.7 N-m (31.5 Ft. Lbs.) in tightening the pipe joint at the thermostat inlet, particularly if teflon pipe compound is used, as the
valve body may be damaged.
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 hot or cold water connections on heater. Any heat applied to the hot or cold water
supply fittings will permanently damage them.
The inlet gas pressure to the water heater must not exceed
25 mbar (10.1” w.c) for Natural gas or 57.5 mbar (23.14” w.c.)
Propane gas. For purposes of input adjustment, the nominal 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.
NOTICE: A check valve must be installed in the cold-water
inlet as per local and national codes and regulations.
7. CHECKING MANIFOLD GAS PRESSURE - ONLY QUALIFIED
SERVICE PERSONNEL MAY VERIFY THE MANIFOLD GAS
PRESSURE. A manometer, spigot (provided in the Use and Care
Manual bag), and 8mm (5/16 inch) ID flexible hose are required.
Turn the thermostat to the lowest temperature setting. Turn gascock to “PILOT” position. Remove 1/8” NPT pressure tap plug,
located on bottom of thermostat, beside burner supply tube.
Tighten spigot into this threaded hole using standard procedures
to assure correct fit and leak free joints. Connect one end of flexible hose to manometer. Back the screw in the spigot out until
only two threads hold screw in place. Push other end of hose
over barb of spigot, turn thermostat to required setting and measure pressure.
4. RELIEF VALVE — A new combination temperature and pressure
relief valve, complying with the Standard for Relief Valves and
Automatic Gas Shutoff Devices for Hot Water Supply Systems,
ANSI Z21.22, or equivalent local or international standard, must
be installed in the opening provided and marked for the purpose
on the water heater. (Refer to Fig. 3.) No valve of any type should
be installed between the relief valve and the tank. Local codes
shall govern the installation of relief valves.
The pressure rating of the relief valve must not exceed 10.3 bar
(150 psi). This is the maximum working pressure of the water
heater and is marked on the rating plate.
6
Installation
The water heater must be isolated from the gas piping system by
closing the manual gas shut-off valve (Refer to Fig. 3), during
any pressure testing of the gas supply piping at pressures equal
to or less than 57.5 mbar (23.14” w.c.) or as described in local
codes.

10. VENTING - This water heater must be installed with the factory supplied
draft hood in place. (Refer to Fig. 3.) 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 outlet or larger, never smaller. For proper venting in certain
installations a larger vent connector size may be needed.
Tighten the spigot screw and check for gas leaks before placing the water heater in service.
! DANGER
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.
Horizontal vent connectors must be pitched upward to the chimney at
least 2.10 cm per meter (1/4” per foot). Single wall vent connectors must
be at least 15.5 cm (6 inch) from adjacent unprotected combustible
surfaces. Joints of vent connectors should be securely fastened by
sheet metal screws or other approved method.
! WARNING
! WARNING
8. 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 (Refer to Fig. 3). 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 thermostat should also be leak tested immediately
after the water heater is placed in operation.
Failure to install the draft hood and properly vent the
water heater to the outdoors as outlined above can
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 this water heater unless it
is properly vented and has as adequate air supply for
proper operation.
Be sure to inspect the vent system for proper installation at initial start-up; and at least annually thereafter. Refer to Maintenance section of this manual for more information regarding vent
system inspections.
! WARNING
Never use open flame to test for gas leaks, as bodily injury, property damage, or death could result.
! WARNING

or MAINTENANCE instructions, it is recommended that a qualified
person or serviceman perform the work.
G. If your water heater is not equipped with a vent switch it may ONLY be
installed in a room separated from living spaces and provided with
appropriate ventilation directly to the outside.
B. Do Not turn on water heater unless it is filled with water.
C. Do Not turn on water heater if cold water supply shut-off valve is
closed.
! CAUTION
D. 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 vicinity
should be shut off, including their pilot lights, to avoid vapors
igniting.
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 probably 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.
NOTE: Flammable vapors may be drawn by air currents from
surrounding areas to the water heater.
E. Do not allow combustible materials such as newspaper, rags or mops
to accumulate near water heater.
F. If there is any difficulty in understanding or following the OPERATION
3. WATER TEMPERATURE SETTING— The temperature of the water in
the heater can be regulated by setting the temperature dial on front of the
thermostat. (Refer to Fig. 4.) The thermostat was set at its lowest setting
before the water heater was shipped from the factory.

4. ADJUSTMENTS— There are no user adjustments (other than water
temperature selection) required on this water heater. The thermostatic
valve is equipped for total regulation of the main burner and pilot gas
pressures. The burner does not require adjustment.
Figure 4 — Thermostatic Gas Valve.
Safety and energy conservation are factors to be considered when
selecting the water temperature setting of water heater’s thermostat. The
lower the setting the greater the savings in energy and operating cost.
HIGH ALTITUDE— Ratings of gas appliances are based on sea
level operation and need not be changed for installations at elevations up to 609 m (2,000 feet). For installations above 609 m
(2,000 feet), the input must be reduced per the local or national
fuel gas code or equivalent regulation for each 304 m (1,000 feet)
above sea level. Contact the local gas supplier for more information.
! WARNING
NOTE: Low water temperatures can lead to bacterial
growth, while high temperatures increase the risk of
scalding and burns.

Operation
5. SAFETY CONTROLS— The thermostat is constructed with a built in
safety shutoff device designed to shut off the gas supply to the burner in
the event the pilot flame is extinguished for any reason. The thermostat is
also equipped with a gas shut-off device that will shut off the gas supply to
the burner, if the water in the water heater exceeds normal operating
temperatures. Refer to the Troubleshooting Section of this manual, or
contact your dealer for service.
After a very long shut-down period, the water heater’s operation and
controls should be checked by qualified service personnel. Make certain
the water heater is filled before again placing it in operation.
9. DRAINING WATER HEATER—
! CAUTION
6. EMERGENCY SHUTDOWN—
Shut off gas at thermostat gas cock or supply line manual
shut-off valve before draining water from the water heater.
! WARNING
In order to drain water, turn off cold water supply, then it is necessary to
open a hot water faucet or lift the handle on the relief valve to allow air to
enter the tank. Attach a garden hose to the drain valve on the water
heater and direct the stream of water to a drain where it will do no
damage.
Should overheating occur or the gas supply fail to shut off,
turn off the manual gas control valve to the appliance.
If 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.
! DANGER
NOTE: Replace any part of the gas control system which has been
under water.
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.
7. CONDENSATION— Condensation can form on the tank when it is first
filled with cold water. The condensation might also occur with a heavy
water draw and very cold inlet water. Drops of water falling on the burner
can produce a sizzling or pinging sound, and water may also be seen
beneath the water heater. This condition is not unusual, and will disappear
after the water in the water heater becomes heated. If, however, the
condition is continuous, examine the piping and fittings for possible leaks.
10. ANODE— This water heater is equipped with an anode rod designed to
prolong the life of the glass lined tank. Refer to Fig. 3 for location. The
anode rod is slowly consumed cathodically, thereby eliminating or
minimizing corrosion of the glass lined tank. Water sometimes contains a
high sulfate and/or mineral content and together with the cathodic
protection process can produce a hydrogen sulfide or rotten egg odor in
the heated water. Please contact a local plumber or qualified service
personnel to correct this issue.
8. VACATION AND LONG TIME SHUT-DOWN— If the water heater is to
remain idle for an extended period of time, the gas should be turned off to
conserve energy. The water heater and piping should be drained if they
might be subjected to freezing temperatures.
NOTE: Do not remove the anode-rod from the water heater’s tank,
except for inspection and/or replacement, as permanent removal will
shorten the life of the glass lined tank and effect the water heater
warranty.
NOTE: Refer to Hydrogen Gas Caution, in Safety Precautions
Section on page 11.
Maintenance
Properly maintained, your water heater will provide years of dependable
trouble free service. It is suggested that a regular routine maintenance
program be established and followed by the user. It is further recommended
that a periodic inspection of the thermostat, burner, relief valve, internal
flueway and venting system should be made by service personnel qualified
in gas appliance repair.
plumber or qualified service personnel to correct this issue.
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
C. The area near the water heater must be kept free of flammable liquids
such as gasoline or paint thinners, adhesives and other combustible
materials.
1. ROUTINE PREVENTATIVE MAINTENANCE
A. The water heater’s internal flue must be inspected annually to be certain
it is clean by removing the draft hood and flue baffle. (Refer to Fig. 2A.)
When reinstalling the flue baffle make certain it is hung securely by its
hanger at the top of the flue way. Remove any scale that may have fallen
on the burner or floor shield. Reinstall the draft hood. Inspect gas venting
system to make certain vent connector from draft hood to chimney is
properly positioned and securely attached and inspect chimney.
Replace any corroded through vent connector and remove any
obstruction in vent connector or chimney.
For your safety, cleaning of main burner should be
performed ONLY by qualified service personnel, as it
involves disconnection of gas piping and leak testing.
B. Visually inspect the burner annually while firing and pilot burner flame
with main burner off. (Refer to Figure 5 for normal flame pattern.) If any
unusual burner operation is noted, the water heater should be shut off
until qualified service assistance can be obtained. Please contact a local
E. 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 and allow several liters to flush through
discharge line. Make certain the discharged water is directed to an open
drain.
! CAUTION
D. For adequate combustion (proper burner operation) and ventilation, make
certain the flow of air to the water heater is not obstructed.
12
Maintenance
F. 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. Deposits should not be allowed to
accumulate as this can affect the service life of the water heater. It is
suggested that a few quarts of water be drained from the water heater’s
tank every month. If sufficient hard water deposits accumulate, a
rumbling or pounding sound can occur. There is no danger involved and
the efficiency of the water heater is not seriously affected, but the noise
can be annoying. Your plumbing contractor should be contacted to clean
the tank of these deposits.
G. Rapid closing of faucets or solenoid valves in automatic water using
appliances can cause a pounding “water hammer” sound. “Water
hammer” can be described as a banging noise heard in a water pipe
following an abrupt alteration of the flow with resulting pressure surges.
Strategically located risers in the water pipe system can be used to
minimize the problem. Also water hammer arresting devices are usually
available from your plumber or local plumbing supply store.
Figure 5. — Main Burner and Pilot Flame Pattern
! DANGER
Before manually operating the relief valve, make certain no
one will be exposed to the danger of coming in contact with
the hot water released by this valve. The water may be hot
enough to create a SCALD hazard. The water released
should be directed to a suitable drain to prevent injury or
damage.
2. ANODE ROD INSPECTION—The anode rod should be removed from
the water heater’s tank annually for inspection and replaced when more
than 15 cm (6”) of core wire is exposed at either end of the rod. Refer to
Fig. 3 for anode rod location. Make certain cold water supply is turned off
before removing anode rod. Please contact a local plumber or qualified
service personnel to correct this issue.
NOTE: If the temperature and pressure relief valve on the
water heater discharges periodically, this may be due to
thermal expansion in a “Closed” water system. Contact
the water supplier or your plumbing contractor on how to
correct this. DO NOT plug the relief valve outlet.
