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 24 and 25, to properly re-
place logs.
• Use a vacuum cleaner to remove any carbon buildup on logs.
• Replace log(s) if broken. See
Replacement Parts
on page 33.
• Replace ember material periodically as needed. See
Replace-
ment Parts
on page 33.
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
condensation 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
33). This glass door panel is a complete unit. No
substitute materials may be used.
CLEANING AND
MAINTENANCE
CAUTION: Wear gloves and safety glasses while
handling or removing broken glass. Do not remove if
glass is hot. Keep children and pets away from glass.
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 mate-
rial, 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
each heating season, depending on the usage and circumstances
present. Refer to
Removing/Replacing Glass Door
, page 22 of this
manual when removing glass door for cleaning.
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.
Use only the tempered glass door replacement intended for this
fireplace (see
Replacement Parts
, page 33 for detail on ordering).
No substitutions may be made. See
Removing/Replacing Glass
Door
, page 22 for instructions for replacing glass door.
