"Winterization" procedures in this manual.
MINIMUM & MAXIMUM TEMPERATURE
SETTING FOR YOUR FURNACE
This furnace is designed for minimum continuous return-air temperature
of 60°F (16°C) or intermittent operation down to 55°F (13°C) such as
when used with a night setback thermostat. Return-air temperature must
not exceed 80°F (27°C). Failure to follow these return-air temperature
limits may affect reliability of heat exchangers, motors, and controls.

factory-authorized replacement parts, kits, and accessories when
modifying this product.
Installing and servicing of heating equipment can be hazardous due to
gas and electrical components.
Only trained and qualified personnel should install, repair, or service
heating equipment. Untrained personnel can perform basic maintenance
functions such as cleaning and replacing air filters.
All other operations must be performed by trained service personnel.
Observe safety precautions in this manual, on tags, and on labels
attached to the furnace and other safety precautions that may apply.
With proper maintenance and care, your furnace will operate
economically and dependably. Instructions for basic maintenance are
found on this and the following pages. However, before beginning
maintenance, follow these safety precautions:
WARNING
!
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal injury or death.
Turn off electrical power supply to your furnace and install lockout tag
before removing the access doors to service or perform maintenance.
CAUTION
!
CUT HAZARD
Failure to follow this caution may result in personal injury.
Although special care has been taken to minimize sharp edges, be
extremely careful when handling parts or reaching into the furnace.
Wear safety glasses, gloves, and appropriate protective clothing.
FILTERING OUT TROUBLE
NOTE: The manufacturer has specified filters which will enable your
furnace to provide lasting comfort and efficiency throughout its life.
Contact your dealer to help you choose filters for your furnace that both
collect dirt before it enters your furnace, as well as provide a low
resistance to circulating air. Avoid filters that report high cleaning
efficiencies, but do not allow air to pass easily through them.
Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations.

UNIT PERFORMANCE HAZARD
Failure to follow this caution may result in unit component damage.
Never operate your furnace without a filter in place. Doing so may
damage the furnace blower motor. An accumulation of dust and lint on
internal parts of your furnace can cause a loss of efficiency.
!
PERSONAL INJURY HAZARD
Failure to follow this caution may result in personal injury.
Use care when cutting support rods in filters to protect against flying
pieces and sharp rod ends. Wear safety glasses, gloves, and appropriate
protective clothing.
A dirty filter will cause excessive stress on the furnace, heat exchanger,
and blower motor, and can cause it to overheat and automatically shut
down. The furnace filter should be checked every four weeks and be
cleaned or replaced if necessary.
If installed with factory-specified disposable media filter, check or
replace filter before each heating and cooling season. Replace disposable
media filter at least once a year.
If your furnace filter needs replacing, be sure to use the same size and
type of filter that was originally specified.
The air filter for the furnace may be located an external filter cabinet
attached to the side or bottom of the furnace casing. If the air filter has
been installed in another location, contact your dealer for instructions.
To inspect, clean and/or replace the air filter(s), follow these steps:
1. Turn off electrical supply to the furnace (see
2. Remove air filter from the filter cabinet.
a. Remove filter cabinet door (see
NOTE: It maybe necessary to remove one thumbscrew.
b. Slide air filter out of furnace. Keep dirty side up (if dirty) to
avoid spilling dirt (see
3. Inspect the filter. If torn replace it.
NOTE: If a washable filter was supplied with the furnace and has been
replaced by:
• Disposable media filter-Do not clean. If dirty, replace only with
media filter having the same part number and size. Install with
airflow direction arrow pointing towards blower.
• Electronic Air Cleaner (EAC), refer to the EAC Owner's Manual for
maintenance information.
4. If washable filter, wash filter (if dirty) in a sink, bathtub, or outside
with a garden hose. Always use cold tap water. A mild liquid
detergent may be used if necessary. Spray water through filter in the
opposite direction of airflow. Allow filter to dry.
5. Reinstall clean air filter.
6. Turn on electrical supply to the furnace.
If your furnace air filter needs to be replaced, be sure to use a
factory-authorized filter of the same size that was originally specified.
Use the filter tables and compare your furnace size with the proper filter
size.
