VENTING SPECIFICATIONS
FOR INSTALLATION
The fireplace chimney flue and vent must be
drafting 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 chim-
ney. If the smoke spills out into the room,
extinguish the flame and remove any ob-
struction 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 (see Figure 5, page 8).
