be equal to or greater than the input to the water heater.  
Water heaters intended to be shipped to Canadian  
destinations may have the temperature and pressure relief  
valve factory installed. Any replacement valve must meet the  
latest edition of CAN 1-4.4, the Standard for “Temperature,  
Pressure, Temperature and Pressure Relief Valves and  
Vacuum Relief Valves.”  
WATER PIPING  
Pipes and fittings should be installed in compliance with the  
installation drawing. Makes sure the dip tube is in the cold  
water fitting and water connections are made correctly.  
Have the installer show you where the water shut-off valve for  
the water heater has been installed so that you know where  
and how to shut the water off. It is recommended that such a  
valve be located in close proximity to the cold water inlet of  
the water heater. (See installation drawing, Figure 3).  
Relief valve piping must terminate 6 inches above a floor  
drain or external to the building. Do not thread, cap or plug the  
end of this discharge line. Be certain that no contact is made  
with any live electrical part. Do not connect discharge line  
directly to drain. See figure 3. To prevent bodily injury, hazard  
to life or damage to property, the relief valve must be allowed  
to discharge water in the event of excessive temperature or  
pressure developing in the water heater. The function of the  
temperature and pressure relief valve is to discharge water in  
quantities should circumstances demand. If the discharge  
pipe is not directed to a drain as shown in Figure 3 or other  
suitable means, the water flow may cause property damage.  
Connect the cold water supply to the fitting marked “COLD”  
the hot water outlet to the fitting marked “HOT”. Do not apply  
heat to either of these fittings. It is imperative that no heat  
be applied to these fittings as they contain a non-metallic  
tube. When marking these connections, always use a good  
grade of pipe joint compound and be certain that all fittings  
are drawn up tight.  
The discharge line:  
After piping has been installed, allow tank to fill up with water  
and check connections for leaks. To ensure complete filling of  
the tank, allow air to exit by opening the nearest hot water  
faucet until a constant flow of water is obtained.  
1. Shall not be reduced by a coupling or any other restriction;  
2. Must not be plugged, or blocked;  
3. Must be of material capable of withstanding 210oF,  
without distortion;  
Check your area for water hardness. Hard water conditions  
can shorten tank life or cause excessive maintenance. When  
hard water conditions exist water softening is the best answer  
to protect both the water heater and the appliances using hot  
water.  
4. Must be installed so as to allow complete drainage of  
both the temperature and pressure relief valve and dis-  
charge lines;  
5. Must terminate at an adequate drain; and  
Pressure Build-up in a Water System  
6. Must not have any valve installed between the relief  
valve and the water heater.  
During the heating cycle of the water heater, the water  
expands, creating a pressure build-up in the water sys-  
tem. The water supply meter may contain a check valve or  
back-flow preventer, creating a closed water system. A  
method of controlling thermal expansion would then be  
required. Contact the water supplier or local plumbing  
inspector for instructions to control the situation.  
Failure to install and maintain a new,  
properly listed temperature and  
pressure relief valve will release the  
manufacturer from any claims which may result  
from excessive temperature or water pressure.  
A temperature and pressure relief valve must be installed  
on the water heater (150 p.s.i maximum pressure setting.  
See Temperature and Pressure Relief Valve, below.)  
Should the relief valve discharge water, a potentially  
dangerous situation may be indicated and must be inves-  
tigated. Have the operation of the heater checked by a  
qualified service person.  
WARNING:  
Do not attempt to operate this water heater  
with the cold water inlet valve close.  
Manually operate temperature and pressure  
relief valve at least once a year. Standing  
clear of the outlet, (discharge water will be  
hot), lift and release the lever handle on the  
temperature and pressure relief valve to  
make sure the valve operates freely.  
Temperature and Pressure Relief Valve  
For protection against excessive pressure and/or  
temperatures, a temperature and pressure relief valve must  
be installed in the opening marked “T&P VALVE” - a design  
certified by a nationally recognized testing laboratory that  
maintains periodic inspection of production of listed equipment  
or materials, as meeting the requirements of Relief Valves and  
Automatic Gas Shutoff Devices for Hot Water Supply  
Systems, ANSI Z 21.22 - latest edition. Pressure rating of the  
valve must not exceed the working pressure shown on the rat-  
ing plate of the water heater. The discharge capacity must  
NEVER OPERATE THE HEATER IF IT IS NOT  
COMPLETELY FILLED WITH WATER. TO  
MAKE SURE THE HEATER IS FILLED, OPEN  
THE HOT FAUCET OF TAP UNTIL A FULL  
FLOW OF WATER IS VISIBLE WITH NO AIR  
ESCAPING.

A FIRE OR EXPLOSION COULD RESULT.  
jurisdictions.  
Install the gas piping as indicated in Figure 2. Use only new  
pipe and fittings with sound, clean-cut pipe thread. Sealing  
compound must conform to the applicable code for pipe  
sealing compound approved for use with natural gas and  
propane. It is important to have a readily accessible manu-  
al shut-off valve in the gas line supplying the heater, close  
to the heater. A drip leg must be installed ahead of the gas  
control valve to help trap sediments and foreign material.  
The maximum inlet gas pressure to the appliance must not  
exceed the gas pressure marked on the rating plate: 10.5”  
W.C. for natural gas and 13” W.C. for propane gas.  
The minimum supply pressure for the purpose of input  
adjustment is 1” above manifold pressure. The appliance  
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 of 1/2 psig (3.5 kPa)  
A ground-joint union must be installed ahead of the gas  
valve to permit easy removal of the unit.  
The appliance must be isolated from the gas supply piping  
system by closing its individual manual shut-off valve during  
any pressure testing of the gas supply piping system at  
least pressures equal to or, less then 1/2 psig(3.5kPA)  
Pipe sizing and the number of fittings used must conform to  
the National Fuel Gas Code, Natural Gas Installation Code  
B.149.1 or Propane Gas Installation Code B149.2.  
The appliance and its gas connection must be leak tested  
before placing the appliance in operation.  
The input rating of the appliance should be checked against  
the actual input and the manifold pressure adjusted to give  
the correct input. In no case should the input exceed the  
rated input. Overfiring and damage to the appliance will  
result. High altitude installations require an input check  
since overfiring is more likely.  
All leak testing must be done with soapy water solution.

VENTING  
VENT TOP  
OR CAP  
To carry off the products of combustion, a vent pipe must be  
attached to the drafthood of the heater and connected to a  
chimney vent of adequate height and area. Venting  
connections should be made in accordance with all codes  
and ordinances which apply.  
COMMON  
CHIMNEY VENT  
MANIFOLD  
Ensure that the vent pipe is securely fastened to the draft hood  
and that the draft hood is properly attached to the heater. For a  
single heater installation the vent pipe must be sized no small-  
er than the flue size of the heater. Horizontal runs of vent pipe  
should be installed with a rise of at least 1/4” per foot of length.  
The vertical connector rise of vent pipe above the draft hood,  
before any fittings, should be as great as possible.  
VENT  
CONNECTOR  
TEE  
CAPPED  
CONNECTOR  
RISE  
When more then one heater is installed and the vents are  
combined, the area of the horizontal manifold and common  
vent should be at least equal to the area of the largest single  
vent, plus 50% of the area of all other vents joining it (see  
Vent Size Chart below) (For example, to combine two 6” vents  
with a 5” vent, the area of the combined vent would be equal  
to 28 + 28/2+20/2 equals 52 square inches - use a minimum  
9 inch common vent and manifold). Units with larger inputs  
must be vented below others. When using a common vent  
connector, it shall be at the highest practical level.  
The chimney vent must be extended at least two feet higher  
than any obstruction located within 10 feet.  
Where a back draft exists, the cause must be determined and  
corrected. A flue cap on the chimney vent may correct the sit-  
uation. However, if the back draft cannot be corrected, if long  
horizontal vent pipe runs are necessary, or if a suitable flue  
cannot be obtained, a mechanical exhaust may be required to  
ensure proper venting and combustion.  
Some local codes prohibit connecting a gas heater to a flue or  
chimney with coal or oil fired equipment. Therefore, these  
connections should be avoided. However, where a separate  
chimney is not available, the flue pipe from the water heater  
should enter the common flue or chimney at a point ABOVE  
the flue pipe from the coal or oil fired equipment.

Flue Damper Venting  
FLUE DAMPER  
The vent pipe (flue pipe) must be installed without restriction  
or reduction in size. Slope the horizontal run upwards to the  
chimney at least 1/4” per foot. Fasten all joints with sheet  
metal screws. (See Figure 4)  
Flue Damper Installation  
For Models equipped with a flue damper, the following instructions  
must be followed. It is recommended to leave a minimum 24”  
clearance from the actuator side of the flue damper for service  
access.  
Venting must be inspected every three months for blockage  
and problems due to age of the vent piping.  
Step 1:  
Damper Position Indicator  
Place flue damper on top pan into flue collector. The rail support  
must be screwed to the top pan. The three pre-drilled holes on the  
casing top must align with the three holes on the rail support. The  
rail support must fit flush with the casing top.  
The damper position indicator can be found on the flue collar  
of the flue damper. (See Figure 4).  
Heater Wiring  
Step 2:  
Install the draft hood which is supplied with the heater in the carton  
to the heater top. Fasten the draft hood with the four sheet metal  
screws supplied.  
Follow local codes for all electrical work. To reduce risk of  
shock or possible electrocution, the heater must be electrical-  
ly grounded in accordance with local codes or, in the absence  
of local codes, with the National Electrical Code, ANSI /  
NFPA 70.  
Step 3:  
Remove junction box cover plugs. Remove flue damper cover. The  
wiring harness provided plugs into the four plug female molex con-  
nector (use strain relief connector provided). Molex plugs mate  
together one way only.  
If any of the original wiring must be replaced use only type  
105oC thermoplastic or equivalent.  
To manually set the damper in the open position, see diagram below.  
NOTE: THE FLUE DAMPER MUST BE IN THE OPEN  
POSITION WHEN APPLIANCE, PILOT AND OR MAIN  
BURNERS ARE ON. THIS SHOULD BE CHECKED BY  
THE INSTALLER BEFORE LEAVING.

FOR YOUR SAFETY  
READ BEFORE LIGHTING  
AIR SUPPLY  
Ensure that adequate ventilation is available to supply  
make-up air for proper combustion. Openings sufficient to  
provide one square inch of free area for each 1,000 BTU/hr.  
input rating of all appliances must be provided for this  
purpose. Where heaters are installed in a confined space,  
two openings - one near the top of the enclosure and one  
near the bottom each having a free area of one square inch  
for each 1,000 BTU/hr. input - shall be provided. Refer to  
standard CAN 1-B.149-1 or .2 or local codes for complete  
ventilation and combustion air requirements.  
WARNING:  
If you do not follow these instructions exactly, a fire  
or explosion may result, causing property damage,  
personal injury or loss of life.  
IMPORTANT  
STANDING PILOT INSTRUCTIONS  
If an exhaust fan is in the same room as a heater, adequate  
air openings must be provided in the walls, otherwise, air  
may be drawn into the room through the chimney or flue  
causing poor combustion.  
A. This appliance has a pilot which must be lighted by hand.  
When lighting the pilot, follow these instructions exactly.  
B. BEFORE LIGHTING smell all around the appliance area  
for gas. Be sure to smell next to the floor because some

1. The burner air openings (primary air) may need clean  
ing. Observe if lint and dust have accumulated.  
LP (PROPANE) GAS MODELS  
LP. GAS IS HEAVIER THAN AIR.  
2. With a small brush, clear away lint and dust which may  
have accumulated. Observe if any debris has fallen on  
the burner which obstructs the burner ports. See Figure  
5 for a view of a comparison of a good flame. If in  
doubt, consult a competent serviceman or your local  
gas company.  
Should there be a leak in the system, the gas will settle  
at FLOOR LEVEL. Basements, crawl spaces, closets and  
areas below ground level will serve as pockets for the  
accumulation of the gas.  
3. Turn thermostat dial up to turn burner “ON”  
4. Loosen the air shutter retaining screw.  
Out Of Fuel  
5. With a screw driver, lightly tap the air shutter and move  
it in the more open direction (Figure 5)  
When your LP tank runs out of fuel, turn off gas at all gas  
appliances. After LP tank is refilled, all appliances must be  
re-lit according to the manufactures’ instructions.  
6. If yellow flame disappears, tighten the screws, taking  
care not to move air shutter again.  
NOTE:  
While moving the air shutter dust particles will be dis-  
turbed and drawn into the burner causing a bright, lumi-  
nous flame. This is temporary and must not be confused  
with a yellow tipped, carbonizing flame. Carbonizing  
flames are often called “candling” flames because they  
look like flames from a burning candle.  
MAINTENANCE INSTRUCTIONS  
Venting System Inspection  
Every three months, when inspecting the burner flame, an  
inspection of the venting system should be made.  
7. When flames appear normal (Figure 5) replace burner  
access cover.  
Check these points:  
8. Turn thermostat down to the previous setting.  
1. Are the draft hood relief openings free of obstruction?  
2. Is the flue pipe securely attached?  
Tank Clean-Out  
3. Is the flue pipe cemented into the chimney or are  
cracks and loose cement visible?  
A) A clean-out opening is provided for periodic cleaning of  
the tank. Gas must be shut off and the heater drained  
before opening the clean-out.  
CORRECT ANY DEFECTS IMMEDIATELY  
Burner Maintenance  
B) To clean heater through the clean-out opening, proceed  
as follows:  
- remove outer door from side of the side of the casing.  
- peel back the insulation covering the clean-out flange.  
At least every three months, check the burner and pilot  
flames. The burner flames must be a soft blue flame with no  
yellow tips. Yellow tips indicate a carbonizing flame which  
can, depending on severity, deposit carbon (soot) on the  
combustion chamber and flue passages.  
- remove the six (6) hex head screws securing the tank  
clean-out plate and remove the plate.  
- remove lime, scale or sediment using care not to  
damage the glass lining of the tank.  
Figure 5  
- inspect the clean-out gasket, if it shows sign of wear a  
new gasket is required.  
TOO LITTLE AIR.  
YELLOW FLAME.

- position the insulation, and replace outer door.  
SHARP, CLEARLY DEFINED  
INNER CONE, BLUE TIPS  
NOTE:  
In some areas where there is a lot of lime in the  
water, the tank should be cleaned more frequently,  
otherwise the heater will develop excess scale on the  
bottom and cause a banging, rumbling or boiling  
noise and will affect the recovery, operation and life of  
the heater.

the tank cools sufficiently (approximately 120oF) the switch will  
close. This will re-establish the electrical circuit and permit the  
pilot to function through E.C.O. If recycling of the E.C.O.  
occurs, it indicates that a problem exists in the heater or  
installation which must be corrected.  
GENERAL HOUSEKEEPING  
As a precaution against fire, and to maintain an adequate flow  
of combustion air to the heater:  
-
Keep the appliance area clear and free from com-  
bustible material, gasoline and other flammable  
vapours and liquids.  
The non-recycling E.C.O. switch will open when water temper-  
ature exceeds fixed cutoff temperature. It will not close circuit  
again when the water temperature cools. When this contact  
opens, it indicates that a problem exists in the heater which  
must be corrected before a new control is used in the water  
heater. If single cycle energy cutoff switch opens contact, the  
control must be replaced.  
-
-
Keep any ventilation and combustion air openings  
unobstructed.  
do not pile cartons, papers or combustible materials on  
top or around the heater. Maintain clearances to  
combustible construction unobstructed.  
For gas control replacement, contact your local gas utility, or  
a qualified service person. The replacement control must be  
an identical model to the control which has been removed.  
CAUTION: Label all wires prior to disconnection  
when servicing controls. Wiring errors can cause  
improper and dangerous operation.  
TEMPERATURE AND  
PRESSURE RELIEF VALVE  
TEMPERATURE  
The temperature and pressure relief valve (T&P valve) is a  
part of the safety equipment on the water heater. In order to  
keep the T&P valve functioning properly, operate the valve at  
least once a year by lifting the manual lever until water dis-  
charges from the overflow pipe.  
Set temperature as low as possible to provide an adequate  
supply of hot water. This will reduce heat loss and extend the  
life of the glass lining. Every “notch” on the dial of the gas con-  
trol corresponds to approximately a 10o increment in water  
temperature.  
CAUTION: The water flowing from the valve will be HOT.  
Keep hands and feet away from the stream of water.  
Take care that discharging water does not damage any  
flooring, carpeting or other parts of the building which  
may be damaged by water.  
HIGHER SETTING INCREASES  
THE RISK OF SCALD INJURY  
In households with children or invalids and elderly, select a  
lower temperature setting. To reduce the risk of scalding,  
valves for reducing point of use temperature by mixing cold  
and hot water are available. Consult a licensed plumber or the  
local plumbing authority.  
See also section on T & P valve in the “installation Section”  
WATER TEMPERATURE REGULATION  
EXPOSURE TO WATER  
The thermostat is adjusted to its lowest temperature position  
when shipped from the factory. The temperature of the water  
can be selected by setting of the temperature dial on the front  
of the gas control. The normal setting corresponds to approx-  
imately 130oF.  
IMPORTANT  
Should the water heater be subjected to flooding,  
fire or other unusual condition, turn off gas at the  
manual gas shut-off valve and water at the inlet  
valve to the heater. Do not put the heater in  
operation until a qualified gas technician has  
inspected and replaced any part of the gas control  
system that has been underwater.  
GAS CONTROL  
The gas control is equipped with an energy cutoff switch,  
E.C.O., which functions as a high limit safety switch. When  
the water temperature exceeds the fixed cutout temperature,  
the switch will cycle open. This will interrupt the pilot valve cir-  
cuit and stop all gas flow through the control.  
TAMPERING  
Two types of E.C.O. limits are manufactured:  
Tampering with the thermostat, gas valve, igniter control or  
temperature and pressure relief valve is DANGEROUS and  
voids all warranties. Only qualified personnel should service  
these components.  
1. Recycling  
2. Non recycling.  
The recycling E.C.O. switch will open when water temperature  
exceeds fixed cutoff temperature. When the temperature in

CATHODIC PROTECTION  
CAUTION  
Depending on the model, two or three magnesium anodes are  
factory installed inside the tank to provide corrosion protection  
and to extend tank life. Permanent removal of the anode(s) for  
any purpose will void the warranty.  
Hydrogen gas can be produced in a hot water sys-  
tem served by this heater that has not been used  
for a long period of time (generally two weeks or  
more). Hydrogen gas is extremely flammable. To  
reduce the risk of injury under these conditions, it is  
recommended that a hot water faucet be opened  
for several minutes at the kitchen sink before using  
any electrical appliances 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. There  
should be no smoking or open flame near the  
faucet at the time it is opened.  
Read the warranty attached to this water heater for a full  
explanation of the time period that parts and the heater are  
warranted.  
It is advisable to inspect the condition of the anode(s) at  
certain intervals. A two year period may be a guide to begin  
with. The life of the anode depends on many factors and can  
differ greatly from one location to another.  
To remove and anode, proceed as follows:  
1. Turn the gas off at the inlet to the heater.  
2. Turn water off at the cold water inlet valve.  
3. Open a nearby HOT water tap.  
DISHWASHING MACHINE REQUIREMENTS  
4. Drain approximately two pails full of water from the  
heater.  
The heater may be operated to supply the 180oF sanitizing  
rinse water required by the public health code for dishwashing  
machines. In such installations, the heater should be located  
as close as possible to the dishwasher. If the distance between  
the dishwasher and heater is greater than 5 ft. the pipes  
should be insulated and recirculation of the 180oF water should  
be provided. The circulation flow rate should be enough to  
provided 180oF to the dishwasher, however, the rate should be  
low to minimize turbulence inside the water heater.  
5. Remove the vent pipe and the draft hood. Remove the  
hot and cold water connections.  
6. Lift up the other casing top and the insulation under it.  
7. Lift up the inner flue collector. NOTE: the flue collector  
has a lip extending out on the circumference which can  
be used for lifting.  
8. With a 1-1/6” hex socket wrench, loosen the anode from  
the fitting in the tank top.  
Flow pressures to the dishwasher above 25 or below 15  
pounds per square inch will not produce a proper rinse spray.  
If flow pressure to the dishwasher is high a pressure reducing  
valve should be used in the 180oF line to deliver water at 20  
pounds per square inch for the rinse cycle. If the flow is too low  
a pressure booster should be installed.  
NOTE: The anodes have been factory installed using a  
power tool. It will be necessary for a second person to  
restrain the heater. A few sharp blows on the handle of  
the socket wrench will loosen the anode adapter.  
If an impact wrench (power driven) is available, this is an  
easy way to remove an anode.  
MULTIPLE HEATERS IN SINGLE SYSTEM  
9. Lift the anode up and inspect. There should be at least  
3/8” to 1/2” of anode diameter left. The surface may be  
rough, full of pits and crevices, but this is normal.  
When two or more water heaters are installed into a single sys-  
tem, the following precautions must be taken to ensure that  
each heater is able to deliver it’s full rated capacity of hot water  
for maximum system efficiency.  
If there is less than approximately 3/8” diameter left, the  
anode needs to be replaced.  
10. Apply a good grade of pipe dope to the threads of the  
anode adaptor and screw securely into the tank top.  
1. Gas supply piping must be large enough (see table 1)  
2. The combined flue pipe must be large enough. see  
local codes.  
11. Replace the flue collector. Make sure it seals all around  
the circumference.  
3. The water connections must be properly manifolded.  
12. Replace the insulation and the casing top.  
13. Re-connect hot and cold water lines.  
WATER ODOR PROBLEMS  
14. Replace the draft hood and the vent pipe. NOTE: If the  
vent pipe shows signs of corrosion or damage, replace it  
with new material. See section on “Venting”  
When the area water trace mineral content is high. The odor of  
the water may be strong. Replacing the water by draining it  
completely and flushing then refilling it may help. Chlorination  
and replacement of magnesium anode with aluminum anode  
may help if the problem persists.  
15. Open the cold water inlet valve and fill the tank.  
16. Check for leaks.  
17. To relight burners, follow “Lighting Instructions”

A water heater should not be installed in a location where water damage can result if the water heater develops a leak. This is particularly important if the water heater  
is installed in a multi-story building.  
In such cases, provision should be made in the installation for a means of directing to a drain pipe, any water escaping from the water heater.

when so requested.

with all components properly and securely packed and if inspection by the Company proves the part or heater to be defective in workmanship or material.
