Inspecting Burners; Cleaning And Maintenance - Desa (V)T32N series Owner's Operation And Installation Manual

INSPECTING bURNERS

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 dur-
ing shipping and handling. Call a qualified service
person to readjust the pilot if necessary.
The height of the thermopile must be 3/8"
to 1/2" above pilot flame as shown if Figure
54. The thermocouple must be at a height of
about 1/8" above the pilot flame. The flame
from the pilot burner must extend beyond both
the thermocouple and thermopile.
If your pilot assembly does not meet these
requirements:
• turn fireplace off (see To Turn Off Gas to
Appliance, page 28)
• see Troubleshooting, page 33

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 55 shows a typical flame pattern.
If burner flame pattern differs from that described:
• turn fireplace off (see To Turn Off Gas to
Appliance, page 28)
• see Troubleshooting, page 33

GLASS DOOR
Pilot Burner
1/8"
Thermocouple
Glass must be cleaned periodically. During
start-up it is normal for condensation to form
on the inside of the glass causing lint, dust,
and other airborne particles to cling to the
glass surface. During initial start-up a slight
film may form on the glass due to paint curing.
The glass should be cleaned several times
with a non-ammonia, nonabrasive household
cleaner and warm water after the first two
weeks of operation. Thereafter, clean the
glass two or three times during each heating
season, depending on the usage and circum-
stances present. Refer to Removing/Replac-
ing Glass Door on page 24 of this manual
when removing glass door for cleaning.
