13.1 Utility systems
13.2 Heating system
13.3 Description
The heating system is comprised of the heat exchange section of the exhaust muffler, a shut-off
valve mounted on the center of the firewall, a push-pull control on the instrument panel, outlets, and
flexible ducting connecting the system.
13.4 Operation
Ram air is ducted through a heat exchange section of the exhaust muffler, to the shut-off valve in
a chamber on the rear side of the firewall, where it is distributed into the cabin. The shut-off valve
operated by a push-
pull control marked “Warm”, located beneath the switch panel, regulates the volume
of heated air entering the system. Pulling the control full out supplies maximum flow, and pushing control
in gradually decreases flow, shutting off flow completely when the control is fully pushed in.
13.5 Trouble shooting
Most of the operational troubles in the heating and ventilating systems are caused by a sticking or
binding air valve and its control, damaged air ducting, or defects in the exhaust muffler. In most cases,
the valve or control can be freed by proper lubrication. Damaged or broken parts must be repaired or
replaced. When checking control, ensure valve responds freely to the control movement, that they move
in the correct direction, and that they move through their full range of travel and seal properly. Check that
hoses are properly secured, ensure to replace hoses that are burned, frayed or crushed. If fumes are
detected in the cabin, a thorough inspection of the exhaust system should be accomplished. Refer to
applicable paragraph in Section 10 for this inspection. Since any holes or cracks may permit exhaust
fumes to enter the cabin, replacement of the defective parts is imperative because fumes constitute an
extreme danger.
