CABINET
Air Passageways
• Use a vacuum cleaner or pressurized air to
clean.
Exterior
• Use a soft cloth dampened with a mild soap
and water mixture. Wipe the cabinet to remove
dust.
LOGS
• If you remove logs for cleaning, refer to In-
stalling Logs, pages 11 and 12, to properly re-
place logs.
• Replace log(s) if broken or chipped (dime-sized
or larger).
MAIN BURNER
Periodically inspect all burner flame holes with
the heater running. All slotted burner flame holes
should be open with yellow flame present. All
round burner flame holes should be open with a
small blue flame present. Some burner flame holes
may become blocked by debris or rust, with no
flame present. If so, turn off heater and let cool.
Remove blockage. Blocked burner flame holes
will create soot.
