CLEANING AND MAINTENANCE
Glass Door
Pilot and Burners
Logs
Venting System
PILOT AND BURNERS
• Remove ember material before cleaning burners and replace
when cleaning is complete.
• Burner and controls should be cleaned with compressed air to
remove dust, dirt, or lint.
• Use a vacuum cleaner or small, soft bristled brush to remove
excess dust, dirt, or lint.
LOGS
• If you remove logs for cleaning, refer to Installing Logs, Lava Rock,
and Glowing Embers, pages 23 and 24, to properly replace logs.
• Use a vacuum cleaner to remove any carbon buildup on logs.
• Replace log(s) if broken. See Replacement Parts on page 34.
• Replace ember material periodically as needed. See Replace-
ment Parts on page 34.
VENTING SYSTEM
Conduct annual inspection of the venting system following these guidelines:
1.
Check areas of venting system that are exposed to the weather for
corrosion (rust spots or streaks and, in extreme cases, holes). Have
these items replaced immediately by a qualified service person.
2. Remove the vent cap and shine a flashlight into the vent. Re-
move any foreign material.
3. Check for evidence of excessive condensation. Continuous con-
densation can cause corrosion of caps, pipes, and fittings and can
be caused by having excessive lateral runs, too many elbows, or
exterior portions of the system being exposed to cold weather.
4. Inspect joints to verify that no pipe section or fitting has been
disturbed and loosened. Check mechanical supports such as
wall straps for rigidity.
WARNING: Only parts supplied by the manufac-
turer should be used when replacing broken or dam-
aged glass door panel (see
Replacement Parts, page
36). This glass door panel is a complete unit. No
substitute materials may be used.
CLEANING AND
MAINTENANCE WARNING: Do not operate fireplace with the glass
door removed, cracked, or broken.
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.
WARNING: Do not use abrasive cleaners as this
may damage glass. Use a nonabrasive household glass
cleaner to clean glass. Do not clean glass when hot.
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.
GLASS DOOR
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
CAUTION: Do not vacuum if pieces are hot.
If glass has been broken, carefully remove glass door (see Remov-
ing/Replacing Glass Door, page 22). Vacuum all glass pieces with
a shop vac.

each heating season, depending on the usage and circumstances
present. Refer to Removing/Replacing Glass Door on page 22 of this
manual when removing glass door for cleaning.
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 dangerous. Inspect the flames after installa-
tion to ensure proper installation and performance.
Figure 56 shows a typical flame pattern.
If burner flame pattern differs from that described:
• turn fireplace off (see To Turn Off Gas to Appliance, page 25)
• see Troubleshooting, pages 29 through 31

Use only the tempered glass door replacement intended for this
