VENTING SPECIFICATIONS FOR
INSTALLATION
The fireplace chimney flue and vent must be draft-
ing properly. To check the vent for proper drafting:
Light a tightly rolled newspaper on one end and
place it at the inside front edge of the fireplace.
Observe the smoke and be sure the vent is properly
drawing it up the chimney. If the smoke spills out
into the room, extinguish the flame and remove any
obstruction until proper venting is achieved.
The chimney flue damper must be fixed open to
provide a minimum of 29 square inch flue opein

details about minimum flue size.
