Starting the H-45 Type II (Liquid Fuel) Heater when the fuel type is NOT known.
1. If starting the heater when the fuel is NOT known, it should be assumed for safety reasons that the
fuel is gasoline. The heater should, therefore, be started using the gasoline starting method.
2. To start the Type II (Liquid Fuel) heater when the fuel type is unknown, set the fuel selector control
knob (1) in the JP4-8/ GAS position (2) by lifting the fuel selector control knob (1) and turning the
entire control assembly until the fuel selector control knob (1) is set to the JP4-8/GAS position (2).
Release the fuel selector control knob (1) and make sure that the fuel selector control knob (1)
engages in the locking detent.
3. Start the heater as described in the previous section entitled Starting the H-45 Type II (Liquid Fuel)
Heater When The Fuel Type IS Known, and operate for 10 to 15 minutes. If the fire is burning low
and not generating much heat, set the fuel selector knob (1) to the DIESEL position (3).
When operating with gasoline, light the heater as soon as possible after
pouring the cup of fuel in the burner. Throw in a lit match, and stand
General Operating Characteristics Of The H-45 Type II (Liquid Fuel Heater)
The heater is designed to operate at various firing rates, producing
between 20,000 to 45,000 BTUs. A smoking, pulsing, or sooty heater
indicates an overfire or underfire condition.
Viscosity of liquid fuel is not consistent at all times and locations. If the heater appears to be overfiring at
high settings or underfiring at low settings, adjust the fuel flow adjustment knob (4) counterclockwise or
clockwise until the flame is clear, no smoke or soot is observed, and the pulsing stops.
