Water Heater; Before Using The Water Heater - Holiday Navigator 2003 Owner's Manual

The water heater will heat water using two different methods: (1) 120 Volt
AC, supplied either by shore power or the on board generator, or (2) LP-Gas. The
120 Volt AC uses a heating element similar to that of a water heater typically
found in a house. The 120 Volt AC method is efficient if shore power is available.
The LP-Gas incorporates the use of an automatic ignition circuit board operated
by 12 Volt DC. Two thermostats control water temperature: One for the 120 Volt
and the other for the LP-Gas. The manufacturer presets the water temperature.
Water is pumped into the bottom of the water heater tank where it is heated
and discharged out of the top upon use. For easy winterizing, the water heater is
equipped with a temperature and pressure safety relief valve, a by-pass valve and
drain plug.
NOTE: Do not operate the water heater by either function
without water in the water heater tank. Damage to the
thermostats and electric heating element can occur.
Before using the water heater, purge all trapped air
from the water system.
To purge the air and pressurize the system:
• Turn the water heater Bypass Valve to Normal
Flow.
• Turn on the water pump or hook up to city water.
• After the system pressurizes, inspect the water
heater for water leaks.
• Turn on the hot and cold valves for each water
faucet, one at a time. Operate each faucet inside
and outside of the motorhome. Run each faucet
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.
WARNING: IF YOU SMELL GAS extinguish all open flames
and turn off the main gas supply. Liquid propane is highly
volatile, highly explosive and extremely dangerous. Explosion,
fire, property damage, injury or death can result. Propane is a
"heavy" gas and will lay on the floor and "hide" in corners.
Open all windows and doors. Do not touch any electrical
switches. They may cause a spark that can ignite. Evacuate the
motorhome and shut off the LP valve. Contact a qualified service
center to have the problem correctly diagnosed and repaired
before resuming operation.
