has gone into “lockout” mode and must be
restarted. If this happens, turn the Water Heater
LP switch off for about 5 minutes, then turn it
back on.
For Electric Operation
Press the Water Heater Electric switch to ON.
The shoreline must be connected or generator
running for electric operation.
For Quick Recovery Operation
(Dual Heating)
Turn ON both Water Heater switches -
propane 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.
To Replace the Air Gap:
1. Turn off the Water Heater switch and
incoming water supply (city water and/or
demand pump).

CAUTION
Hot water can escape from tank causing
injury. Operate this valve only when the
water heater and engine cooling system
are cold.
