FUEL REGULATOR AND SHUTOFF VALVE. (Refer to Figure 21-4)

This unit provides preset, regulated fuel pressure as well as remove shutoff to the heater, regardless of fuel

inlet pressure variations. It is set for 7.5 +/- .5 psi. The shutoff valve is operated by a solenoid.

DUCT SWITCH. (Refer to Figure 21-5)

This switch is installed in the ventilating manifold upstream from the heater to sense the ventilating air outlet

temperature. To select the desired cabin temperature, the switch may be adjusted manually from a high of 250°F
+/- 10° downward through a range of 146°F +/- 6°. The switch has a differential of 15°F +/- 5° at any given
setting.

COMBUSTION AIR BLOWER.

This centrifugal type blower supplies combustion air to the combustion chamber of the heater.

VENTILATING AIR BLOWER.

This blower is attached to the inlet end of the heater assembly and provides a source of ventilating air through

the heater. Ram air from the air intake is used during flight.
