INSPECTING bURNERS
Check pilot flame pattern and burner flame pat-
terns 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 re-
quirements:
• turn fireplace off (see To Turn OFF Gas to Ap-
pliance, page 25)
• see Troubleshooting, page 32
BURNER FLAME PATTERN
Burner flames will be steady; not lifting or floating.
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 danger-
ous. 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 Ap-
pliance, page 27)
• see Troubleshooting, page 32

CLEANING AND
MAINTENANCE
WARNING: Turn off fireplace
and let cool before cleaning.
CAUTION: You must keep
control areas, burners, and
circulating air passageways of
fireplace clean. Inspect these
areas of fireplace before each
use. Have fireplace inspected
yearly by a qualified service
person. Fireplace may need
more frequent cleaning due to
excessive lint from carpeting,
bedding material, pet hair, etc.
GLASS DOOR
WARNING: Handle glass
door panel with care. Do not
strike, slam, or otherwise abuse
glass. Do not operate fireplace
with the glass door removed,
cracked, or broken.
WARNING: Do not use abra-
sive cleaners as this may damage
glass. Use a nonabrasive house-
hold glass cleaner to clean glass.
Do not clean glass when hot.
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, non-
abrasive 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 circumstances
present. Refer to Removing/Replacing Glass Door
on page 24 of this manual when removing glass
door for cleaning.
