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
effi cient 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 System:
Turn water heater bypass valve (located
at the back of the water heater) to Normal
Flow. If necessary, install a drain plug.
Fill the fresh water tank or hook to city
water.
Turn on the water pump or city water.

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.
