Burner Air Shutter Adjustment Procedure
WARNINGS
• Air shutter adjustment should
only be performed by a quali-
fied professional service
technician.
• Ensure front glass panel are
in place and sealed during
adjustment.
CAUTIONS
• Carbon will be produced if the
air shutter is closed too much.
Any damage due to carboning
resulting from improperly
setting the air shutter is not
covered under the warranty.
• The air shutter door and nearby
appliance surfaces are hot.
Exercise caution to avoid
injury while adjusting flame
appearance.
1. Locate adjustment rod and adjust air shutter
to the standard setting as shown in Figure
15 (adjustment rod is located in the lower
control compartment).
Note: Rotating the adjustment rod down
to decrease air and up to increase air.
2. Light appliance (follow lighting procedure
on lighting label in control compartment or
see the lighting instructions, Pages 22 and
24 in this manual).
3. Allow the burner to operate for at least 15
minutes while observing the flame con-
tinuously to ensure that the proper flame
appearance has been achieved (see Figures
12, 13 or 14). 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.

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 17.

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 16).
To light the burner, refer to the lighting instruc-
tions on Page 22.
