Cleaning the Log Set and Firebox
Do NOT handle these logs with your bare hands. Always wear
gloves to prevent skin irritation. During the annual inspection and
maintenance appointment, the service person should clean dust, lint,
and any light accumulation from the logs and the rebox area. An
extra-soft brush should be used on the logs as they are extremely
fragile; a vacuum cleaner may be used on the rebox. If at any time
the logs cannot be removed or installed without forcing, the cause
must be found. The logs must never be forced.
CAUTION
The ceramic logs are durable when handled and
installed properly. However, they are delicate and may be
damaged easily if not handled with care. Handling damage
to the ceramic logs is not covered by warranty.
DO NOT HANDLE LOGS WHILE THEY ARE HOT. ALLOW PLENTY
OF TIME FOR THE APPLIANCE TO COOL COMPLETELY BEFORE
HANDLING.
PLEASE NOTE
It is normal for appliances fabricated of steel to give off some
expansion and/or contraction noised during the start up or
cool down cycle. Similar noises are found with your furnace
heat exchanger or car engine.
