MOTOR AID (Auxiliary Water Heating
System)
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 Auxiliary Coach
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.
LP GAS FURNACE
(SUBURBAN)
Start Up:
o Start Up:
1.
Open the LP gas tank valve
by turning
fully counterclockwise
2. Place the
FAN MODE
switch in ‘
Auto
’
position. (Place the FAN SPEED switch in
whichever position you wish. For colder
temperatures we recommend ‘Lo’.
3. Press the
Temperature Selector
button
Up
or Down
until the desired temperature
appears in the Display.
4. Move THERMOSTAT switch to ‘Heat’ posi-
tion (or to ‘Gas Heat’ if you have the
optional Heat Pump system.) The Furnace
fan should start to blow immediately.
5. After about 30 seconds, the furnace burner
will light.
NOTE: Metal coatings used during manufacture
of the furnace burner parts may smoke
when the furnace is used for the first
time, which may also set off your smoke
alarm. If this happens, provide adequate
ventilation of the smoke to avoid a nui-
sance smoke alarm at this time. We do
not recommend removing the smoke
alarm battery. If it were inadvertently left
disconnected, the smoke alarm would be
inoperative.
6. The furnace will now cycle off and on auto-
matically as the thermostat demands just like
a household furnace.
Leave by-pass valve handle in NOR-
MAL FLOW position if draining
water and blowing out water lines.
Place in BYPASS position ONLY
when using antifreeze solution in
water lines.
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.
