• The more offsets in the vent system, the larger
the air shutter opening will need to be.
• An appliance operated with the air shutter
opened too far, may have fl ames that appear
blue and transparent. These weak, blue and
transparent fl ames are termed anemic.
• Propane models may exhibit fl ames which
candle or appear stringy. If this is present and
persists, adjust the air shutter to a more closed
position, then operate the appliance for a few
more minutes to ensure that the fl ame normal-
izes and the fl ames do not appear sooty.
The following chart is provided to aid you in
achieving the correct air shutter adjustment
for your installation.
Burner Air Shutter Adjustment Procedure
1. Locate adjustment rod and adjust air shutter
to the standard setting as shown in Figure
56 (adjustment rod is located in the lower
control area).
Note: Rotating the adjustment rod coun-
terclockwise decreases air and clockwise
increases air.
2. Light appliance (follow lighting procedure
on lighting label in control compartment or
see homeowners manual).
3. Allow the burner to operate for at least 15
minutes while observing the fl ame continu-
ously to ensure that the proper fl ame appear-
ance has been achieved (see Figure 52). 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 fl ame
appearance is achieved.
• If fl ame stays lowered blue, adjust the
air shutter, incrementally, to a more
closed position until the proper fl ame
appearance is achieved.
4. Leave the control knob (off/pilot/on) in the
ON position and the burner OFF/ON switch
OFF (& remote switches, if applicable).
5. When satisfi ed that the burner fl ame ap-
pearance is normal, close the lower control
compartment door then proceed to fi nish
the installation.
