Procedure
Electronic Appliance Checkout
To light the burner, refer to the lighting instruc-
tions on Page 24. Ensure the igniter lights the
pilot. The pilot flame should engulf the flame
sensor as shown in Figure 15.
APPLIANCE CHECKOUT
Millivolt Appliance Checkout
The pilot flame should be steady, not lifting
or floating. Flame should be blue in color with
traces of orange at the outer edge.
The top 3/8" (10 mm) at the pilot generator
(thermopile) and the top 1/8" minimum (tip)
of the quick drop out thermocouple should be
engulfed in the pilot flame. The flame should
project 1" (25 mm) beyond the hood at all three
ports (see Figure 14).
To light the burner, refer to the lighting instruc-
tions on Page 22.

3. Allow the burner to operate for at least 15 min-
utes while observing the flame continuously
to ensure that the proper flame appearance
has been achieved (see Figures 11 and 12 on
previous Page). If the following conditions
are present, adjust accordingly.
• If flame appears weak or sooty, adjust
the air shutter, incrementally, to a more
open position until the proper flame
appearance is achieved.
• If flame stays lowered blue, adjust the
air shutter, incrementally, to a more
closed position until the proper flame
appearance is achieved.
4. Leave the control knob (off/pilot/on) in the
ON position and the burner OFF/ON switch
OFF (and remote switches, if applicable).
5. When satisfied that the burner flame ap-
pearance is normal, close the lower control
compartment door (see Figures 11 and 12
on previous Page).
