LUBRICATION
IMPORTANT: DO NOT
attempt to lubricate the bearings on
the blower motor or the induced draft blower motor. Addition
of lubricants can reduce the motor life and void the war-
ranty.
The blower motor and induced draft blower motor are per-
manently lubricated by the manufacturer and do not require
further attention.
It is recommended that the blower motor and induced draft
blower motor 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.
!
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.
