INSTALLATION
The replace chimney ue and vent must be draft-
ing properly. To check vent for proper drafting:
Light a tightly rolled newspaper on one end and
place it at the inside front edge of replace. Ob-
serve smoke and be sure vent is properly drawing
it up the chimney. If smoke spills out into the room,
extinguish ame and remove any obstruction until
proper venting is achieved.
The chimney ue damper must be xed open to
provide a minimum of 43 square inches of free
air opening during operation of this log set. A
multipurpose damper clamp is provided to x the
damper in position.
