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 the System:
• Turn the water heater bypass valve (located at the back of the
water heater) to Normal Flow. If necessary install drain plug.
• 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 fl ows with no bubbles or pockets
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 interior house power.
• 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.
