THEORY OF OPERATION Continued
FUEL-FIRED HEATER SYSTEM (ISSUED TO SELECTED UNITS ONLY)
The winterization kit consists of a fuel-fired heater assembly with an internal water pump. The fuel-fired heater assembly
preheats coolant and internal water pump circulates heated engine coolant through the engine. The fuel-fired heater system
uses a 24 Vdc electric system that powers the heater fuel pump and circulating pump and a resistor circuit that warms EMCP
components. The EMCP resistors are also automatically energized any time the GSC has power applied to it and the
thermostat closes (temperature below 20F (29C).
