Starting the Burner

1. Turn the switch on the wall thermostat to HEAT and adjust the thermostat setting above room

temperature to start the burner.

NOTE: If the burner refuses to start, review the Preparing the Burner for Startup procedure. If,

after repeating this procedure, the burner still refuses to start, check the following system components

for proper functioning:

• Verify that the red wire as shown in the Burner Wiring Diagram (Appendix B) is energized

to230VAC.

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.

3. 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.

WARNING: The observation port gets hot as the

burner fires. To avoid personal injury, always wear

heavy work gloves and safety glasses when opening the port

and viewing the flame.
