SECTION 7 PIPER AIRCRAFT CORPORATION
DESCRIPTION & OPERATION PA-44-180, SEMINOLE
To introduce fresh, unheated air into the cabin during flight, the air
intake should be open and the heater off. Ram air enters the system and can
be individually regulated at each floor outlet. Overhead outlets also supply
fresh air for cabin ventilation. The occupant of each seat can manually adjust
an outlet in the ceiling to regulate the flow of fresh air to that seat area. An
optional fresh air blower may be installed in the overhead ventilation system
to provide additional fresh air flow during ground operation.
An overheat switch located in the heater unit acts as a safety device to
render the heater inoperative if a malfunction should occur. Should the
switch deactivate the heater, the OVERHEAT light on the instrument panel
will illuminate. The overheat switch is located on the aft inboard end of the
heater vent jacket. The red reset button is located on the heater shroud in the
nose cone compartment.
To prevent activation of the overheat switch upon normal heater
shutdown during ground operation, turn the three-position switch to FAN
for two minutes with the air intake lever in the open position before turning
the switch to OFF. During flight, ·1eave the air intake lever open for a
minimum of fifteen seconds after turning the switch to OFF.
The combustion heater uses fuel from the airplane fuel system. An
electric fuel pump draws fuel from the left tank at a rate of approximately
one-half gallon per hour. Fuel used for heater operation should be
considered when planning for a flight.
