Before using the water heater, purge all trapped air from the water system and
water heater.
To Purge the Air and Pressurize the System:
• Remove the access panel to the back of the water heater.
• Turn the water heater Bypass Valve (located at the back of the water
heater) to Normal Flow. If necessary replace drain plug.
• Fill the fresh water tank or hook to city water.
• Turn on the water pump or city water.
• Turn on the hot and cold valves for each faucet, one at a time. Operate
each faucet, inside and outside the motorhome, until a steady stream
of water with no air bubbles or air pockets are present. Do not operate
the water heater until the water system is purged of air.
• After the system pressurizes, inspect the water heater and water
system for leaks.
CAUTION: After purging the water lines and water heater, air
may still be present. Use caution upon opening a hot water
faucet after the first heat cycle of the water heater.
WARNING: IF YOU SMELL GAS extinguish all open flames
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 lay 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 have the problem
correctly diagnosed and repaired before resuming operation.
Water Heater Operation:
• Turn ON the Battery Cut-off switch at the entry door.
• 120 Volt AC is supplied from shore power or the generator.
• The house batteries are charged.
• The primary LP-Gas valve on the LP-Gas tank
is open.
• Ensure the water heater is plugged into the 120
Volt AC outlet.
Heating Water with 120 Volt AC:
• Have either shore power (preferable) or the
generator supplying AC voltage.
• Turn ON the Water Heater 120 Volt switch.
