If the water heater needs to be relit;
1. Open the inner door for at least 10 minutes

and force some fresh air into the

combustion chamber to clear any gas from

the water heater and vent system.

2 Check the vent terminal for blockage.
3. Follow the lighting instruction again.

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 top of the gas control. See Figure 4.

The “LOW” position on the thermostat is the preferred

starting point for setting the temperature/control knob

(approximately 120°F (50°C)).

The lowest setting will maintain the minimum water

temperature if you are going away for an extended

period. The burner may be extinguished if operated

below this temperature.

In households with children or invalids and/or elderly

persons, select a lower temperature setting. To reduce

the risk of scalding, valves for reducing the point of

discharge water temperature by mixing in branch water

lines are available. Please consult a licensed plumber or

plumbing authority.

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 it has been

thoroughly checked by a qualified gas

technician.

Tampering with the thermostat, gas valve or temperature

pressure relief valve is DANGEROUS and voids all

warranties. Only qualified personnel should service these

components.

At least every 3 months, check the burner and pilot

flames. The burner flames must be a soft blue flame with

no yellow tips. Yellow tips indicate a carburizing flame

which can, depending on severity, deposit carbon (soot)

on the combustion chamber and flue passages.

A sheet metal burner is used on natural gas models. See

Figure 5.

The sheet metal burner for Natural Gas has no external

air adjustment. It is fully self-compensating and no

outside adjustment is required. Observe the flame

pattern. Ensure that no debris has fallen on top of the

burner and no foreign objects have been introduced into

the combustion chamber. Ensure that the vent terminal

openings are not obstructed and the inner door to the

combustion chamber is closed.

For gas control replacement, contact your local gas utility,

or a qualified serviceman. The replacement control must

be an identical model to the control which has been

removed.

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.

1. Get all people out of the building.

2. DO NOT light matches.

3. DO NOT touch electrical switches (on or off).

4. DO NOT use an electrical fan to remove gas from

area.

5. SHUT OFF GAS at the L.P. tank outside of the

building.

6. IMMEDIATELY call the L.P. Gas Company or the fire

department from a neighbor’s phone. Ask for

instructions. Before hanging up, give your name,

address and telephone number.

7. DO NOT go back into the building. If help is coming,

wait for it outside the building.

When your L.P. tank runs out of fuel, turn off gas at all gas

appliances. After L.P. tank is refilled, all appliances must

be re-lit according to the manufacturers instructions.
