NOTE:
The water heater will attempt 3
ignition cycles after which ignition
lockout will occur indicated by the red
light. Turn switch off then back on.
CAUTION:
Do not operate the water heater
without water. Damage to the
thermostats and electric heating
element can occur.
WARNING:
Before beginning any service or work
on the water heater, make sure the
propane is turned off and the 120 Volt
AC and 12 Volt DC sources have been
disconnected. Failure to do so can
result in explosion, fire or injury.
CAUTION:
It is recommended not to operate the
water heater on propane while the
motorhome is in transit. The water
heater must be off before refueling.
High Temperature Thermostat:
Separate thermostats are used for propane
and AC electric. If a thermostat fails, a high-
temperature safety limit switch will open.
CAUTION:
If the high-temperature safety limit
should open, discontinue using the
water heater. Have the water heater
inspected by a qualified technician
to determine the cause of the over
temperature condition.
Water Heater Bypass Valve:
The bypass valve is located at the back of
the water heater. Turn the valve to the Bypass
position. This prevents water from entering
the water heater. Turn the valve to the bypass
position when winterizing. For normal
operation, set the valve to Normal Flow.
Pressure & Temperature Relief Valve:
The water heater is equipped with a Pressure
& Temperature (P & T) relief safety valve.
The P & T valve is designed to open if water
temperature in the tank exceeds 210° F. (98.8°
C.) or internal pressure exceeds 150 psi. If
water begins to weep from the valve, it may be
due to a loss of the air pocket in the tank and
not a defective valve. See re-establishing the air
pocket.
Re-establishing the Air Pocket:
Water may weep from the P & T valve under
normal operation. This is not necessarily a
faulty valve but more likely caused by lack of
an air pocket and water expansion. The water
heater tank is designed with an internal air
pocket. Eventually, the cyclic expansion of
water will absorb the air pocket.
If weeping from the valve occurs, the air
pocket will need to be re-established utilizing
the following procedure. If the valve continues
to weep after establishing the air pocket,
contact a qualified service center to evaluate
the valve.
CAUTION:
Ensure the water heater is cool prior
to establishing the air pocket.
Turn Off the water heater.
