IT IS RECOMMENDED THAT AN ANNUAL INSPECTION OF
YOUR FURNACE BE DONE BY A QUALIFIED INSTALLER,
SERVICE AGENCY OR THE GAS SUPPLIER.
FILTER MAINTENANCE
Have your qualified installer, service agency or the gas supplier
instruct you on how to access your filters for regular mainte-
nance.
Keep air filters clean at all times. Inspect filters on a monthly
basis and if necessary replace with a clean filter.
After filters are cleaned and returned to the filter rack, be sure fil-
ter rack door is properly reinstalled. If you are not totally sure of
this procedure, consult a qualified installer, service agency or the
gas supplier.

ROUTINE MAINTENANCE
Routine maintenance to be provided by a qualified installer,
service agency or the gas supplier ONLY.
LUBRICATION
The blower motor and induced draft motor are prelubricated by
the manufacturer and do not require further attention.
IMPORTANT: DO NOT attempt to lubricate the bearings on the
blower motor or the induced draft blower motor. Addition of lubri-
cants can reduce the motor life and void the warranty.
The blower compartment and motor should be inspected and
cleaned periodically by your 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 because dirty filters can restrict air-
flow and the motor depends upon sufficient air flowing across and
through it to keep from overheating
