If the outside combustion air kit is not used, air may still be
drawn directly into the fireplace through the lower louvres.
Outside and inside air may be combined by pulling the outside
air lever out as far as possible, and turning the lever 90° to
its locking position.
Should you find a frost build up on the air control box or a
draft from the fireplace, close the outside air lever when the
fireplace is not in use.
Air control box is shipped with inside air cover plate in
open position.

FEATURES
Draft is the force which moves air from the fireplace up through
the chimney. The amount of draft in your chimney depends on
the length of the chimney, local geography, nearby obstruc-
tions and other forces. Adjusting the draft control regulates
the temperature. The draft can be adjusted from a low burn
rate with the handle at the bottom setting to a fast burn rate
with the handle at the top setting. Inadequate draft may
cause back-puffing into the room and may cause plugging
of the chimney. Too much draft may cause an excessive
temperature in the fireplace, glowing red fireplace parts or
an uncontrollable burn which can all lead to a chimney fire
or a permanent damage to the unit.
Do not operate your
fireplace for longer than 30 minutes with the draft control
on 'HIGH' (fully open).
