APPLIANCES AND SYSTEMS

For Electric Operation
Turn on the Water Heater electric element
switch. The shoreline must be connected or
generator running for electric operation.
For Quick Recovery Operation
(Dual Heating)
Turn On both Water Heater switches - the gas
one on the monitor panel and the electric one.
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
Read the operating and safety information
provided in the Water Heater Operation Manual
in your InfoCase.
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).
Gas Water Heater Switch
(Located on Systems
Monitor Panel)
Electric Water Heater Switch
(Typically located near
Systems Monitor Panel)
CAUTION
Hot water can escape from tank causing
injury. Operate this valve only when the
water heater and engine cooling system
are cold.
