A CHECK-UP CHECKLIST

Your furnace represents an important investment in your family's

comfort and your home's value. To keep it performing properly

and to prevent future problems, have a trained service specialist

give your furnace a professional check-up annually. The following checklist can be used as a guideline to proper service:

•Inspect all flue gas passages, burners, heat exchangers, coupling box(es), and inducer assembly.

•Inspect all combustion-air and vent piping inside

structure and vent pipe termination outside the structure.

•Check gas pipes leading to and inside your furnace for leaks.

•Inspect and clean the blower motor and wheel.

NOTE: The inducer and blower motors are pro-lubricated and

require no additional lubrication. These motors can be identified by the absence of oil ports on each end of the motor.

•Inspect and change or clean air filters(s), if necessa U.

•Inspect all supply- and return-air ducts for

obstructions, air leaks, and insulation. Remedy any problem when necessary.

•Inspect the return-air duct connections(s) at the furnace to ensure it is physically sound, sealed to the furnace casing, and terminates outside the space containing the furnace.

•Inspect electrical wiring, connections, and components for loose connections.

•Perform an operational checkout to determine whether your furnace is working properly and if it requires adjustments.

•Inspect all condensate drain tubes and condensate trap

assembly for leaks. The condensate removal system should be cleaned annually by a qualified service agency. Refer to the Service and Maintenance Instructions for further information.

•Examine the physical support of the furnace. Support should be sound with no cracks, sagging, gaps. etc. around the base.

•Check furnace for any obvious signs of deterioration.
