out, a problem exists which must be corrected. Contact a quali-
fied servicer.

The furnace should be inspected by a qualified installer, or ser-
vice agency at least once per year. This check should be per-
formed at the beginning of the heating season by a qualified
technician. This will insure that all furnace components are in
proper working order and that the heating system functions ap-
propriately. Particular attention should be paid to the following
items. Repair as necessary.
Check the burner flames for:
1. Good adjustment
2. Stable, soft and blue
3. Not curling, floating, or lifting off.
• Flue pipe system. Check for blockage and/or leakage. Check
the outside termination and the connections at and inter-
nal to the furnace.
• Combustion air intake pipe system (where applicable).
Check for blockage and/or leakage. Check the outside ter-
mination and the connection at the furnace.
• Heat exchanger. Check for corrosion and/or buildup within
the heat exchanger passageways.
• Burners. Check for proper ignition, burner flame, and flame
sense. Flames should extend directly outward from burn-
ers without curling, floating or lifting off.
• Wiring. Check electrical connections for tightness and/or
corrosion. Check wires for damage.
• Filters. Check that filters are clean and in the proper place-
ment in the furnace or duct system.

WARNING
A return air filter is not supplied with this furnace and cannot be
installed inside the cabinet; however, a means of filtering all of
the return air (intake) must be provided. Your installer will sup-
ply filters at the time of installation. Become familiar with filter
location and procedures for removing, cleaning and replacing
them.
If you need assistance, contact the installer of your furnace or
another qualified servicer.
Filters must be inspected, cleaned or changed every two months
or as required. As a homeowner, it is your personal responsibil-
ity to keep air filters clean. Remember that dirty filters are the
most common cause of inadequate heating or cooling perfor-
mance.
