BURNER PRIMARY AIR HOLES
Air is drawn into the burner through the holes in the tting at the entrance to the burner. These
holes may become blocked with dust or lint. Periodically inspect these holes for any blockage
and clean as necessary. Blocked air holes will create soot.
CARE AND MAINTENANCE
Keep the area around the log set clean and clear of debris.
Occasionally, you may use a soft bristle brush to clean logs.
Once every year a qualied agency or certied chimney sweep should examine and clean
the venting system of the replace.
