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.
