SECTION 6: STARTING AND ADJUSTING THE BURNER

Understanding Burner Startup and Adjustment

Starting and adjusting the burner involves a series of separate procedures which must be accomplished
in sequence without interruption. Review all the procedures before attempting burner startup and
adjustment, paying careful attention to safety information statements.

Preparing the Burner for Startup

1. Turn the switch on the wall thermostat OFF.
NOTE: If your thermostat does not have an OFF setting, disconnect one thermostat wire so
the burner will not run.
2. Turn the main power to the furnace ON.
3. Wait at least 15 minutes until the preheater block is thoroughly warmed up. (Feel the back of the
burner box to make sure the preheater is sufficiently warm. The proving switch on the preheater
block will not allow the burner to start until the block is hot.)
NOTE: The preheater block
will remain warm as long as
power is supplied to the
burner. If the main power
supply is ever turned OFF,
you must wait at least 15
minutes until the preheater
block is thoroughly warm
before starting the burner.
4. Refer to Figure 6A to locate
the air regulator. Loosen the
locking nuts on the air
regulator.
5. Turn the adjustment knobs
on the air regulator
counterclockwise until 1/2"
of the threads on the knob
are exposed. DO NOT back
the knob all the way out.
NOTE: The air gauge will not show
any pressure until the burner starts.
Before starting the burner for the first
time, it is very important to turn the air
regulator completely OFF as
described.
