SECTION 5
PLUMBING SYSTEMS
1. Turn OFF all electric power to the water
heater.
2. Turn OFF the propane supply.
3. Wait five minutes for the propane to clear
the area. If you smell gas then
STOP!
Follow the safety instructions listed in the
vendor manual. If you don’t smell
propane, go to the next step.
4. Turn ON the propane supply.
5. Turn ON electrical power to the water
heater.
6. Make sure the switch located on the water
heater (behind the exterior water heater
compartment door) is ON.
Fig. 5.9 Typical 120-volt AC and 12-volt DC interior water
heater switches
7. Turn either the 12-volt (located on the
monitor panel) or the 120-volt (generally
located in the kitchen or bathroom area)
water heater control switch ON. If the
burner does not light, the system will
automatically attempt two more tries for
ignition before lock-out.
Each ignition cycle will have a 15 second
purge before spark cycle if system is a
three try system.
8. If lock-out occurs before the main burner
lights, turn the water heater control switch
to OFF, wait five seconds and turn the
switch to the ON position. This will restart
the ignition cycle. The first start-up of the
heater may require several ignition cycles
before all the air is purged form the
propane lines.
If the burner will not come on, the
following items should be checked before
calling a service person:
1. See if the switch located on the water
heater (behind the exterior water heater
compartment door) is turned OFF.
2. Check to make sure the propane supply to
the water heater is not empty or turned
OFF.
3. Check to see if the reset button on the
water heater ECO (located behind the
exterior water heater compartment door)
is tripped.
Odor from the hot water system
Many water supplies contain sufficient
amounts of sulfur to produce an odor, often
called “sulfur water.” Sulfur water can be
caused by a chemical action or by bacteria.
Generally, sulfur water is not harmful, only
unpleasant to smell. To eliminate sulfur water
(or bacteria) sanitize the water heater and RV
plumbing system. Odor from sulfur water is
not a service problem.
High altitude deration
Operation of the water heater at high altitudes
may require derating. If the water heater is not
properly derated, lack of sufficient oxygen for
combustion may produce improper burner
operation. Pilot outage caused by burner lift-
off or sooting from a yellow burner may occur,
indicating the possibility of carbon monoxide.
You may also notice a lack of efficiency in
heating the water because of incomplete
combustion of the burner at these higher
altitudes. Consult with the local propane gas
company, your dealer or the water heater
OEM for proper derating of the water heater.
Change out of the orifice (derating) should be
done by the dealer or a qualified service
agency.
It is important that once the RV has returned
to lower elevation (below 4500 feet) any high
altitude deration or other adjustments be
reversed for proper operation of the water
heater.
Pressure & temperature relief valve
You may experience water weeping or
dripping from your water heater's pressure
Do not place a valve between the pressure
and temperature (P&T) valve and the tank.
Do not remove or plug the relief valve
under any circumstances.
