A CHECKUP CHECKLIST
Your furnace represents an important investment in your fam­
ily’s comfort and your home’s value. To keep it in tip-top shape
and as a preventative to 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, cou­
pling box(es), and inducer assembly.
• Inspect all combustion and ventilation air passages and
openings, including combustion air and vent pipe terminations
outside the structure.
• Check gas pipe.s leading to and inside of your furnace for
leaks.
• Inspect, clean, and lubricate the blower motor and wheel as
required.
NOTE: If oil ports are provided, refer to the unit Service and
Maintenance Instructions for blower motor oiling information.
The motor must be oiled by a qualified service technician.
• Inspect and change or clean air fiiter(s) if necessary.
• Inspect all supply- and return-air ducts for obstructions, air
leaks, and insulation. Remedy any problem when necessary.
• Inspect electrical wiring, connections, and component.^ for
loose connections.
• Perform an operational checkout to determine whether your
furnace is working properly and if it requires adjustments.
• Inspect all condensate tubes and connections, condensate
trap assembly, and drain 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; the support
should be sound with no cracks, sagging, gaps, etc. around the
base.
• Check the furnace for any obvious signs of deterioration.
• Your servicing dealer offers an economical service agreement
that covers seasonal inspections; ask for details.

may save the expense of a service call by checking a few things
yourself before calling for service.

your home; ensure they are open and unobstructed.

temperature).
