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 be cleaned periodically by a qualified in-
staller, 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.
!
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.
