OPTIONAL FRESH AIR INTAKE KIT
DVFB-AK-30, FB-AK-2
Optional Fresh Air Intake Kit (Figure 1)
Installation of our 6" fresh air intake kit is simple and easy to complete. This system MUST BE installed before the fireplace is enclosed
with finishing material. The air will be drawn into the cooling layer of the fireplace and be completely separated from the combustion
casing of the direct vent fireplace. Cooler outside air will mix with room air, circulating around the firebox to reduce the heat output and
bring heated, fresh air into the house to provide a more positive balance.
Installing Fresh Air Intake Kit (Figures 2, 3, 4, 5, 6)
1. Remove air dilution cover plate from left side of outer
casing by removing (4) 10 x 1/2" screws (See Figure 2).
2. Attach damper assembly onto left side of outer casing with
(4) 10 x 1/2" screws from Step 1. The 3" damper door tab
will be positioned to the right as the damper assembly is
attached to left side of outer casing.
3. As you face the fireplace, insert damper rod bracket into
left, interior bottom of fireplace for 36/42 models. The
3/4" flange on damper rod bracket must face toward the
rear of fireplace. Align (2) clearance holes on damper rod
bracket with (2) screw holes on left side of hearth pan.
Attach damper rod bracket to the underside of hearth pan
with (2) 10 x 1/2" provided screws (See Figure 3).
