UNIT AND PROPERTY DAMAGE HAZARD
Failure to follow this warning could result in damage to

unit components.
This furnace is designed for continuous return--air

minimum temperature of 60_F (15.6_C) db or intermittent

operation down to 55_F (12.8_C) db, such as when used

with a night setback thermostat. Return--air temperature

must not exceed 85_F (29.4_C) db.

CAUTION

If you choose to leave your furnace on during extended absences

do not set your thermostat lower than the limits shown in the
Caution box above.
To protect your property from damage from potential problems
due to unintended interruptions in utility services or other events,

it is recommended that you either winterize your plumbing
system or have someone check on your house regularly while

you are away.
Your dealer or a licensed plumber can give you additional advice
about winterizing your plumbing system.

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 pre--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 necessary.

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.
