MAIN BURNER
Periodically inspect all burner fl ame holes with
the heater running. All slotted burner fl ame holes
should be open with yellow flame present. All

a small blue fl ame present. Some burner fl ame
holes may become blocked by debris or rust, with
no fl ame present. If so, turn off heater and let cool.
Remove blockage. Blocked burner fl ame holes may
create soot.

monoxide.
NOTICE: Do not mistake orange fl ames
with yellow tipping. Dirt or other fi ne
particles are burned by fireplace,
causing brief patches of orange fl ame.

The front ember burner should have a small blue
fl ame. When the ember material is applied, the
embers will glow red and the fl ame may have a few
small bright yellow tips less than 1/2 inch in height.
The middle burner produces a blue fl ame that im-
pinges upon the ceramic ramp causing the ramp to
glow red with an occasional yellow streak.
The rear burner produces a bright yellow fl ame with
the base of the fl ame being blue.
Figure 49 shows the incorrect burner fl ame.
The front ember burner should not produce yellow
fl ames greater than 1/2" in height or any dark yellow
or orange fl ames.
The middle burner should not produce fl ame that
remains yellow or yellow fl ame that extends above
