Water Heater
The water heater uses two different methods
to heat water: ( 1
) 120 Volt AC, supplied either
by shore power or the on board generator ( 2 )
LP-Gas. The 120 Volt AC function is most
energy efficient when operated from shore
power. The burner for LP-Gas operation is
controlled by an automatic ignition circuit board
powered by 12 Volt DC. Two thermostats control
water temperature, one for 120 Volt AC and the
other for LP-Gas. Thermostat temperature is
preset by the water heater manufacturer and not
adjustable. For ease of winterization, the water
heater is equipped with a tank drain plug and
bypass valve.
NOTE
Refer to the Water Heater OEM
manual for detailed instructions.
Before Using the Water Heater:
Use water to purge air from the water system
and water heater and if necessary, purge FDA
approved RV antifreeze from the system.
To Purge Air and Pressurize the System:
Turn the water heater bypass valve
(located at the back of the water heater)
to Normal Flow. If necessary install drain
plug. Depending on floor plan, the water
heater can be located in one of several
areas. One location is in the bedroom
closet. Another location is an outside
compartment, typically a curbside
compartment.
Fill the fresh water tank or hook to city
water.


Turn on the water pump or city water.
One at a time, open the hot and cold
valves of all faucets until a steady stream
of clear water flows with no bubbles
or pockets of air.
DO NOT operate the
water heater until the system is purged of
air.
Inspect the water heater and water
system for leaks after the water system is
purged of air.
CAUTION
After purging the water lines and
water heater, small air pockets or
hydrogen gas may be present. After
the first heat cycle of the water heater,
initially open hot water faucets slowly
to minimize potential spattering of hot
water.

WARNING
IF YOU SMELL GAS extinguish all
open flame and turn off the primary
LP-Gas valve. DO NOT touch any
electrical switches. They may cause
a spark that can ignite. Open all
windows and doors. Evacuate the
motorhome. Propane is a “heavy” gas
and will lie on the floor and “hide”
in corners. Liquid propane is highly
volatile, explosive and extremely
dangerous. Explosion, fire, property
damage, injury or death can result.
Contact a qualified service center to
repair LP-Gas leaks before resuming
operation.
Water Heater Operation:
Turn on the battery cut-out switch.
120 Volt AC is supplied from shore
power (preferred) or the generator.
The house batteries are charged.
Open the primary LP-Gas valve on the
LP-Gas tank.
NOTE
DO NOT operate the water heater
without water. Damage to the
thermostats and electric heating
element can occur.
Heating Water with 120 Volt AC:
Have either shore power (preferred) or
the generator supplying AC voltage.
Press the water heater 120 Volt switch.
The indicator lamp will glow steady.
NOTE
It is not fuel efficient to use the
generator to operate the water heater
on 120 Volt AC.
