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 as a preven-
tative 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, burn-
ers, heat exchangers, coupling
box(es), and inducer assembly.
• Inspect all combustion-air and vent
piping inside structure and pipe termi-
nations outside the structure.
• Check gas pipes leading to and
inside of your furnace for leaks.
• Inspect and clean the blower motor
and wheel.

NOTE : The inducer and blower motors
are pre-lubricated and require no addi-
tional lubrication. These motors can be
identified by the absence of oil ports on
each end of the motor.
• Inspect and change or clean air fil-
ter(s) if necessary.
• Inspect all supply- and return-air
ducts for obstructions, air leaks, and
insulation. Remedy any problem when
necessary.
• Inspect the return-air duct connec-
tion(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, connec-
tions, 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
35
should be cleaned annually by a quali-
fied service agency. Refer to the Ser-
vice 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 furnace for any obvious signs
of deterioration.
