Personnel Heater Overview and Diagrams
The personnel heater system consists of the personnel heater; the heater fuel pump; the HEATER CONTROL box
containing a START/RUN switch, HI/LO switch, indicator, and 20--amp circuit breaker; a 30--amp circuit breaker;
and related electrical wiring.
The HEATER CONTROL box receives power (+24 -- 28 V dc) through the 30--amp circuit breaker directly from the
vehicle electrical system power source; either batteries or generator, whichever is applicable When the HEATER
CONTROL START/RUN switch is held in the START position, heater ignition is initiated, the HEATER CONTROL
indicator lights, and the heater blower motor is turned on. After heater ignition, the START/RUN switch is set to
RUN to maintain heater operation. The HI/LO switch selects a desired heater output. When the START/RUN
switch is set to OFF, the heater will shut down.
The relationship of the personnel heater system components is shown in the following diagram.
