IMPORTANT
:
We
recommend that your furnace and vents be checked by a qualifi
ed service technician once a
year.
It is good practice to give a quick inspection of your furnace each time you inspect or clean the air fi lter

to check:
•
Check the furnace for obvious signs of deterioration.
4.2 LUBRICA

The circulating air blower, and exhauster motors have sealed bearings.
The bearings contain permanent
special purpose lubricants. Attempting to force common oil into the circulating and exhauster assembly motor
bearings will deteriorate the original lubricant and shorten bearing life.
