Air Shutter Adjustment
1. Open the Lower Grill panel and locate the Air
Shutter adjustment stem extending down from
the firebox floor. See Fig. 28.
2. Loosen the locknut and push the stem to the left
to open the air inlet and allow more air into the
burner. Make adjustments in 1/8” (3 mm) incre-
ments. Retighten the locknut.
3. Reassemble the fireplace including glass assem-
bly. Allow the fireplace to burn 15 -20 minutes on
the HIGH setting, observing the flame continu-
ously.
4. If the flame appears weak, slow, or sooty, repeat
the process described above until the flame is as
desired.
Air Inlet Settings
Natural Gas - 1/4” open
Propane - 1/2” open
IMPORTANT: Run the fireplace for a minimum
of 15 to 20 minutes to produce an accurate
representation of the flame appearance. This
warm-up should be done before and between
any air shutter adjustment.
