CLEANING THE BURNER COMPARTMENT
Because cold air is attracted to the flame during furnace
operation, a buildup of lint from carpeting, bedding, dust,
etc. in the burner area will occur. It is necessary to clean
this area regularly. Use a vacuum cleaner with a narrow
attachment to reach small areas. Be careful in and around
the pilot. A change in its adjustment could be made if
moved during cleaning. A properly adjusted burner with
nearly all gases will produce a flame which has clear blue
cone having a bluish-red or bluish-violet outer mantle.
DANGER: The build-up of any dust, lint or foreign
material in the primary air opening of the burner can
interfere with the proper air gas mixture and can result
in a yellow flame which can produce carbon monoxide
and soot. This condition, if allo wed to develop, can lead
to bodily injury incl uding death. It is imperative that
the burner be kept clean.
