Starting the Burner

1. Adjust the thermostat setting above room temperature to start the burner.
2. Adjusting the Air Regulator:
As soon as the burner starts running, turn the knob on the air regulator clockwise to achieve
proper operating air pressure. Refer to the Initial Adjustment Charts.
NOTE: If the safety reset on the primary control is activated and the burner stops running, see
Section 7 for further instructions on restarting your burner.
Observing the Flame Length:

Visually inspect the flame length through the
observation port. Refer to Figure 6B for an illustration
of the desired flame length. The flame should extend
no more than one-half of the way down the combustion
chamber.

burner fires. To avoid personal injury, always wear
heavy work gloves and safety glasses when opening the
port and viewing the flame.

combustion chamber.

combustion chamber.

combustion chamber.
•
Increase combustion air by opening the
air band on the side of the burner.
