Figure 29. Correct flame pattern at maximum
output. Adjust the air shutter if necessary to achieve
desired flame pattern.
Air Shutter Adjustment
The Air Shutter is set half-open at the factory. This
setting provides good combustion characteristics
with either natural gas or propane in a variety of
operating conditions. You may find, however, that
your particular installation requires adjustment to al-
low for a greater or reduced air/fuel ratio. Follow this
procedure to adjust the air shutter setting.
1. Locate the Air Shutter adjustment stem extending
down from the center of the firebox floor. You will
not be able to see it, however, you will be able to
feel it about 3 inches from the front of the glass
frame. See fig. 29.
2. Loosen the wing nut and pull the stem forward
to open the air inlet to allow more air into the
burner. Push it to the rear to reduce the air. Make
adjustments in 1/8” (3 mm) increments.
Between adjustments, allow the fire to burn 15 -20
minutes on the HIGH setting, observing the flame
continuously.
3. If the flames are lazy, or sooty, move the shutter
forward to increase oxygen. If the flame appears
weak, jet-like, or blue, move the shutter back to
decrease air. Repeat the process until the flame is
as desired. Retighten the wing nut.
Figure 30. All surround panels incorporate hanger
brackets that engage with the hanger tabs on the
firebox.
Hanger Brackets
Surround Assembly
Each of the surround assemblies and front facings is
completely assembled at the factory. No further as-
sembly is required. All assemblies utilize hooked brack-
ets (fig. 30) that simply hang onto the inboard tabs on
the fireplace cabinet as shown in fig. 10 on page 14.
• Be certain the blower power cord is routed to the
front of the insert.
• Hang the Wide Surround first, if appropriate, on the
outboard tabs on the firebox assembly.
• Cast Iron Surround: Remove the upper deflector.
See fig. 8, page 13. Lift the surround assembly by the
upper panel to engage the hooks with the inboard
hanger tabs on the firebox assembly.
• Steel Facings: Open the doors and lift the assembly
by the upper panel to engage the hanger bracket
hooks with the inboard hanger tabs.
Plinth
A plinth panel is incorporated into the Cast Iron Sur-
rounds. If you choose not to use it, the panel can be
removed simply by bending the panel back and forth
to snap it off of the surround backing plate.
Rating Plate Location
The Lighting Instructions / Rating Plate is tethered to
the Valve & Burner controls compartment on the left
side of the fireplace insert. Simply pull it out to refer-
ence when operating the fireplace.
Cast Iron Surround Only:
If you are installing a cast iron
surround, relocate the rating plate underneath the
firebox floor where it will be readily accessible after
the surround is hung in place.
