Appliance Set-Up

A. Outside Air Kit
A source of air (oxygen) is necessary in order for combustion
to take place. Whatever combustion air is consumed by the
fire must be replaced. Air is replaced via air leakage around
windows and under doors. In homes that have tightly sealed
doors and windows, an outside air source is needed.
Installation Instructions
1. Ensure existing access hole in fireplace will not be
covered by the outer can. Existing outside air intake hole
may be under, at the rear, or side of outer can. Outside
air may also enter down existing chimney chase in some
situations.
2. Remove screws holding outer covers in place on both
sides. Place outside air plates in channel as shown
(outside air plates are located in component pack). Re-
install outer covers. (Figure 18.2)
3. Level outer can and install appliance. After installing the
appliance in the outer can, seal the fireplace opening
and trim package with insulation to prevent air leakage
into the room.
