NOTE: The heater operates at various firing rates, producing between 20,000 to 45,000 BTUs. A smoking, pulsing, or sooty heater indicates an over fire or under fire condition.
NOTE: Viscosity of liquid fuel is not consistent at all times and locations. If the heater appears to be over firing at high settings or under firing at low settings, adjust the fuel flow adjustment knob (4) counterclockwise or clockwise until the flame is clear, you don’t observe smoke or soot, and the pulsing stops.
