LUBRICATION

IMPORTANT: DO NOT

attempt to lubricate the bearings on

the blower motor or the induced draft blower motor. Addi-
tion of lubricants can reduce the motor life and void the
warranty.

The blower motor and induced draft blower motor are per-
manently lubricated by the manufacturer and do not re-
quire further attention.

It is recommended that the blower motor and induced draft
blower motor must be cleaned periodically by a qualified
installer, service agency, or the gas supplier to prevent the

possibility of overheating due to an accumulation of dust
and dirt on the windings or on the motor exterior. And, as
suggested elsewhere in these instructions, the air filters
should be kept clean. Dirty filters can restrict airflow. The
motor depends upon sufficient air flowing across and
through it to keep from overheating.

GAS FURNACE (DIRECT DRIVE) INSTRUCTIONS

GAS FURNACE (DIRECT DRIVE)
INSTRUCTIONS FOR CHANGING
BLOWER SPEED

The blower motor is wired for blower speeds required for
normal operation as shown.

If additional blower speed taps are available (leads con-
nected to “M1” and “M2” on the electronic control), speeds
may be changed if necessary to fit requirements of the par-
ticular installation. Reconnect the unused motor leads to
“M1” or “M2.” Check motor lead color for speed designation.

Heating speeds should not be reduced where it could
cause the furnace air temperature to rise to exceed the
maximum outlet air temperature specified for the unit.

IMPORTANT: 

Always check air temperature rise after

changing the heating speed for any reason.

!

WARNING

DISCONNECT THE ELECTRICAL SUPPLY TO THE
FURNACE BEFORE ATTEMPTING TO CHANGE THE
BLOWER SPEED. FAILURE TO DO SO CAN CAUSE
ELECTRICAL SHOCK RESULTING IN PERSONAL IN-
JURY OR DEATH.

!

CAUTION

DO NOT OPERATE THE SYSTEM FOR EXTENDED PE-
RIODS WITHOUT FILTERS. A PORTION OF THE DUST
ENTRAINED IN THE AIR MAY TEMPORARILY LODGE
IN THE AIR DUCT RUNS AND AT THE SUPPLY REGIS-
TERS. ANY RECIRCULATED DUST PARTICLES WILL

BE HEATED AND CHARRED BY CONTACT WITH THE
FURNACE HEAT EXCHANGER. THIS RESIDUE WILL
SOIL CEILINGS, WALLS, DRAPES, CARPETS AND
OTHER HOUSEHOLD ARTICLES.

WARNING

THESE INSTRUCTIONS ARE INTENDED AS AN AID TO
QUALIFIED SERVICE PERSONNEL FOR PROPER IN-
STALLATION, ADJUSTMENT AND OPERATION OF THIS
UNIT. READ THESE INSTRUCTIONS THOROUGHLY BE-
FORE ATTEMPTING INSTALLATION OR OPERATION.
FAILURE TO FOLLOW THESE INSTRUCTIONS MAY RE-
SULT IN IMPROPER INSTALLATION, ADJUSTMENT,
SERVICE OR MAINTENANCE, POSSIBLY RESULTING IN

FIRE, ELECTRICAL SHOCK, CARBON MONOXIDE POI-
SONING, EXPLOSION, PROPERTY DAMAGE, PERSONAL
INJURY OR DEATH.

DISCONNECT MAIN ELECTRICAL POWER TO THE
UNIT BEFORE ATTEMPTING ANY MAINTENANCE.
FAILURE TO DO SO CAN CAUSE ELECTRICAL
SHOCK RESULTING IN PERSONAL INJURY OR
