WARNING: Do not operate re-
place with glass door unlatched,
removed, cracked or broken.
PILOT AND BURNERS
• Remove 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
• Use a vacuum cleaner to remove any
carbon buildup on logs.
• Replace material periodically as needed.
See Replacement Parts.
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 im-
mediately by a qualied service person.
2. Remove the vent cap and shine a ash-
light into the vent. Remove any foreign
material.
3. Check for evidence of excessive con-
densation. Continuous condensation can
cause corrosion of caps, pipes and ttings
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 tting has been disturbed and loos-
ened. Check mechanical supports such
as wall straps for rigidity.
