The fireplace chimney flue and vent must be
drafting properly. To check the vent for
proper drafting: Light a tightly rolled news-
paper on one end and place it at the inside
front edge of the fireplace. Observe the

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 must remain open a mini-
mum of 3" at all times during the operation
of this log set.
