Furnace
The Airstream furnace is an American Gas
Association approved Suburban unit designed
specifically for travel trailers. It has a sealed
combustion system with a dual blower for
maximum air circulation. One blower cir¬
culates room air while the other draws in air
for combustion. The adjustable louvered heat
registers control warm air flow while cold air
returns through the galley cabinet toe kick
opening.
The heat duct system also circulates warm air
around the holding tank, water tank, and
one-stop-service center, a vital feature when
operating in below freezing weather.
The Suburban furnace is thermostatically
controlled. When the thermostat calls for
Furnace Controls (21 Ft.)
heat, the blower starts and only after it has
reached nearly full speed will the burner light.
After the temperature set on the thermostat is
reached the blower will continue to run for a
short time removing most of the remaining
heat from the furnace as well as forcing the
combustion gases from the heat exchanger.
To turn the furnace off for an extended
period of time turn the thermostat (A) to its
"OFF" setting and turn the manual gas valve
on lower exterior of the trailer below furnace
to its "OFF" position (perpendicular to the
gas line). Operating instructions are printed
inside the furnace door.
Trouble-free
operation
of
the

furnace will depend on your adherence to
recommended operating procedures and pre¬
Furnace Controls (23-31 Ft.)
cautions. Corrections of possible malfunctions
presented here will be helpful in an emer¬
gency situation, but servicing should be done
by a dealer. One note of caution regarding
flue gases: they are vented from the furnace
to the outside of the trailer through a vent in
the outside wall. Do not in any way obstruct
this vent by placing clothing or other flam¬
mable material on the vent assembly. Check it
often to make certain it does not become
clogged.
The furnace may be lighted with the electro¬
magnetic lighter or a match.
1. Set the thermostat (A) to the "OFF"
position.
2. Unlatch the furnace door, and open it.
3. Turn on the manual gas valve.
