AUXILIARY HEATER
The auxiliary heater, located under the dinette, is plumbed into the radiator
system.
Two "tees" are located between the engine and the front heater.
The water lines to the heater are routed under the floor.
A shut off valve
can be used to shut off the hot water circulation in the summer, or control
the heat to some degree.
By using the two speed dash fan, along with the
water valve, the temperature output can be varied through a wide range.
WATER HEATER
Your motorhome uses a water heater with a motor aide feature.
This
feature circulates radiator cooling through an exchanger in the water heater
as you drive.
It is plumbed from the same hoses that supply hot water to
the auxiliary heater.
For further information on your water heater see the
Appliance Section of this manual.
The water heater with motor aide has
caused some complaints.
It seems that once you take your motorhome out
for a long drive you can't light the burner of the water heater.because
the water is already hot!
