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 a usable tem-
perature in a few hours of highway 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 Auto-
motive 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:
1. Open the LP gas tank valve by turning fully
counterclockwise.
2. Move THERMOSTAT switch from Off to
Heat and press the Temp Selector button
(Up/Down arrows) until the desired tempera-
ture is shown in the display.
3. Furnace fan will start to blow immediately
after setting thermostat.
4. After about 30 seconds, the furnace burner
will light.
5. The furnace will now cycle off and on auto-
matically as the thermostat demands just like
a household furnace.
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
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.
