BURNER pRIMARY AIR HOLES
Air is drawn into the burner through the holes
in the fitting at the burner entrance. These
holes may become blocked with dust or lint.
Periodically inspect these holes for any block-

MAIN BURNER
Periodically inspect all burner flame holes with
the fireplace running. All slotted burner flame
holes should be open with yellow flame pres-
ent. All round burner flame holes should be
open with a small blue flame present. Some
burner flame holes may become blocked by
debris or rust, with no flame present. If so, turn
off fireplace and let cool. Remove blockage.

WARNING: If yellow tipping
occurs, your fireplace could pro-
duce increased levels of carbon
monoxide.
NOTICE: Do not mistake orange
flames with yellow tipping. Dirt
or other fine particles enter the
fireplace and burn causing brief
patches of orange flame.
