NOTE: It is normal for the new wall furnace to give some odor the rst time it is burned. This is due to the curing of
the paint and any undetected oil from the manufacturing process.
It is recommended to burn a new wall furnace for at least two (2) hours the rst time that it is used.
CAUTION: You must keep control areas and circulating air passageways of heater clean. Inspect these areas
of heater before each use. Have heater inspected yearly by a qualied service person. Heater may need
more frequent cleaning due to excessive lint from carpeting, bedding material, etc. Verify proper operation
after servicing.
WARNING: Turn off heater and let cool before cleaning.
Verify Proper Operation After Servicing.
