Inspecting Burners - Desa CD36RN Owner's Operation And Installation Manual

Check pilot flame pattern and burner flame
patterns often.
PILOT ASSEMBLy
The pilot assembly is factory preset for the
proper flame height. Alterations may have
occurred during shipping and handling. Call
a qualified service person to readjust the pilot
if necessary.
The position and pattern of the pilot flames
in relation to the sensing devices should be
as shown in Figures 68 and 69 depending
on model.
If you pilot assembly does not meet these
requirements:
• turn fireplace off (see To Turn Off Gas to
Appliance, page 33 or 36 depending on
model)
• see Troubleshooting, page 39

BURNER FLAME PATTERN
Burner flames will be steady; not lifting or float-
ing. Flame patterns will be different from unit
to unit and will vary depending on installation
type and weather conditions.
If the vent configuration is installed incorrectly,
the flames will lift or "ghost". This can be dan-
gerous. Inspect the flames after installation to
ensure proper installation and performance.
Figure 68 shows a typical flame pattern.
If burner flame pattern differs from that de-
scribed:
• turn fireplace off (see To Turn Off Gas to
Appliance, page 33 or 36 depending on
model)
• see Cleaning and Maintenance, page 38
