COMBUSTION AIR KIT MODEL AK4
(OPTIONAL)
The outside air kit may be installed on the left side of the fireplace
only. The vent can be installed through the outside wall or a
ventilated crawl space. The handle to operate the damper door for
the outside air inlet will be located inside the left “screen pocket” of
the firebox (see Figure 30). Pull the handle to open or push to close.
APPLIANCE ENCLOSURE
Before finishing the enclosure around the appliance, inspect all joints
around the outer surround. Any gaps between the nailing flanges and the
framing should be sealed with noncombustible insulation or caulking.
If the appliance is mounted on a raised platform, it must be a
continuous surface and not on blocks without a solid surface. This
will prevent the entry of cold air by means of conduction through the
total bottom of the appliance. (see Figure 31).
CAUTION: Air inlet ducts are not to terminate in
attic space.
