Burner Flame Appearance
Once the unit is lit, observe the flame pattern and
adjust as necessary. Also, a periodic visual check of
the burner flame should be performed. The burner
flames can be adjusted by means of the air shutter.
To determine if the burner flame needs adjustment,
it is necessary to view the flame pattern with the
valve output at its highest setting. Allow the unit to
operate for 10 minutes enabling the entire unit to
reach temperature and for the flame pattern to
stabilize. The flame pattern should be similar to the
one shown in Photo 1. There are several guidelines
to aid in determining if the flame pattern is correct:
1. The flame should not be dirty, smoky, sooty, or
lick the top of the stove.
2. The flame should not rise off the burner; this is
called “lifting”.
3. Flames should not impinge heavily on the log
set. They should “fit” through the pre
-formed
spaces designed in the log set.
