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.

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 obstructions and other forces. Adjusting the draft
control regulates the temperature. The draft can be ad-
justed 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, glow-
ing 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).
