APPLIANCES & INTERIOR FEATURES
8-8
Manually operate the pressure thermostat re-
lief switch at least once a year. OPERATE THIS
VALVE ONLY WHEN THE WATER HEAT-
ER AND COOLING SYSTEM ARE COLD!
To Replace the Air Gap:
1. Turn off the water heater switch and incom-
ing water supply (city water and/or demand
pump).
2. Open a faucet in the motor home.
3. Pull the handle of the P-T valve straight out
and allow water to flow until it stops.
4. Let the handle of the P-T valve snap shut.
5. Close the faucet before switching the water
heater on.
Manually operate the pressure temperature re-
lief valve at least once a year. OPERATE THIS
VALVE ONLY WHEN THE WATER HEAT-
ER AND COOLING SYSTEM ARE COLD!
Water Heater Circuit Breaker
A circuit breaker is located behind the service
panel on the rear side of the water heater.
If the water heater will not operate, first check
that the water heater power switch is on, then
check the water heater breaker on the load center
panel.
If the switch and breaker are both on, then
check the breaker at the rear of the water heater.
If the rear breaker is not tripped, see your dealer
for service.
MOTOR AID
The motor aid uses heat from the chassis en-
gine cooling system to heat water in the water
heater while driving. Hoses are routed from the
engine to a heat exchanger surrounding the water
heater tank.
Under normal conditions, the entire contents
of the water heater can be heated to about 140
°
F
in about two hours or 100 miles of driving. This
means you can have hot water at the faucets im-
mediately upon arriving at a site, or even while
driving if needed.
The motor aid also increases the capacity of
the engine cooling system, allowing the engine to
run cooler under many conditions.
Motor Aid Water Heater and Rear Auxiliary
Heater Maintenance
Have your authorized dealer check all hose
clamp connections on the rear automotive heater
and the motor aid water heater at least every six
months and tighten them if necessary. We also
recommend that you periodically lubricate the
rear heater control cable (models 22QD & 22HD)
with powered graphite or a silicone based spray
lubricant to aid in ease in operation.
LP GAS FURNACE (SUBURBAN)
Your furnace is equipped with an automatic
ignition circuit which lights the main burner
when the thermostat demands heat.
The gas furnace is designed to provide safe
and efficient heat throughout the interior of your
motor home through the use of the LP gas and
12-volt electrical systems. The LP fuel is con-
verted to heat at the burner and heats the metal
heat exchanger. A fan switch inside the furnace
turns the blower on automatically when the heat
exchanger reaches a pre-set temperature. The
blower then forces this heat out through the front
of the furnace.
P-T Valve
Open
Any leak in the heat exchanger or its
supply or return lines could cause loss
of coolant and subsequent engine fail-
ure. We recommend that you periodi-
cally inspect these connecting lines
and the heater to insure that no leaks
have developed.
