Operating Instructions
Before starting the heater, perform a safety check: all components must be firmly fastened, check for fuel
leaks.
To start the heater; turn the control knob to “high” (turn the knob clockwise), push heat button, the blower
motor will start running. After about 1 minute the fuel pump will start pumping the fuel. If the fuel is not
ignited in a short period of time the glow pin will turn off for about 1 minute and then it will start the process
again. Upon initial startup the heater may require several start attempts to bleed air out of the fuel lines.
