SECTION 4 –
APPLIANCES AND SYSTEMS
4-10
Be sure the water heater is filled with water
before starting either electric or propane gas
operation.
To fill the water heater, turn the
Water Pump switch on and open a hot water
faucet anywhere in the motorhome. When water
begins to flow steadily from the faucet, the water
heater is full.
For Propane Gas Operation
Press the “WATER HTR GAS” switch on the
Multiplex Monitor Panel.
The “Pilot Out” light will glow for about 10-
15 seconds, then it will go out. The “Heater On”
indicator will remain lit. If the “Pilot Out” light
comes on during gas operation, it means that the
burner has gone into “lockout” mode and must be
restarted. If this happens, turn the Water Heater
switch off for about 5 minutes, then turn it back
on.
For Electric Operation
Press the “WATER HTR ELECT” switch on
the Multiplex Monitor Panel.
The shoreline must be connected or generator
running for electric operation.
For Quick Recovery Operation
(Dual Heating)
Turn On both Water Heater switches (Gas and
Electric). This will help reheat the water heater
tank more quickly than a single source would
alone. Use this mode when you are using a larger
than normal volume of hot water.
Further Information
See the Water Heater manufacturer’s
operation manual provided in your InfoCase for
complete operating instructions, safety warnings,
and maintenance information.
PRESSURE-TEMPERATURE
RELIEF VALVE
On occasion, water may be seen seeping from
the water heater pressure temperature relief
valve. This is no cause for repair or replacement
of the valve.
Normally there is an air gap at the top of the
water heater tank, which acts as a pressure buffer.
In time, however, heated water may expand and
fill this air gap, causing a slight increase in water
pressure. This may cause the P-T valve to “weep”
until the air gap is manually replaced.
