all gas appliances and pilot lights. Gas appliances must never be
operated while vehicle is in motion. Unpredictable wind currents
may be created which could cause flame reversal in the burner
tube, which could result in fire damage. The thermal cut off fuse
could also be unnecessarily activated resulting in a complete
shutdown of the water heater requiring replacement of the thermal
cut off. See maintenance of electronic ignition water heaters for
further explanation of the thermal cut off.
LP tanks must be filled by a qualified gas supplier only.

HOW TO OPERATE YOUR WATER HEATER
Do not smoke or have any flame near an open faucet.
•
If water heater has not been used for more than two weeks, hydrogen
gas may form in water line. Under these conditions to reduce the risk
of injury, open hot water faucet for several minutes at kitchen sink
before you use any electrical appliance connected to hot water system.
If hydrogen gas is present, you will probably hear sounds like air
escaping through the pipe as water begins to flow.
• Do not tamper with pilot orifice.
• Do not operate without water in tank.
PILOT OPERATION
1. Water heater may be equipped with a White Rodgers
Robertshaw Unitrol
2. Turn gas control valve knob (
3. Wait at least five minutes to allow accumulated gas in burner
compartment to escape.
FOR WHITE RODGERS
a. Turn lighting control knob (7-B) to PILOT position and hold
against stop while lighting pilot burner.
b. Allow pilot to burn thirty seconds then release lighting control
knob.
c. Turn lighting control knob (7-B) to ON position.
d. If pilot does not remain lit, repeat operation allowing longer
period before releasing lighting control knob.
e. Set temperature selection lever (7-A) at mark between warm and
hot position.
f. Close access door.
FOR A ROBERTSHAW UNITROL
a. Turn lighting control dial (7-B) to PILOT position.
b. Depress and hold reset push button (7-A) while lighting pilot
burner (7-C).
c. Allow pilot to burn thirty seconds before releasing reset push
button.
d. If pilot does not remain lit, repeat operation allowing longer
period before releasing reset push button.
