4.0 ROUTINE MAINTENANCE BY HOMEOWNER

4.1

AIR FILTER

DO NOT OPERATE YOUR FURNACE OR AIR CONDITIONER FOR EXTENDED PERIODS OF
UM
A portion of the dust entrained in the air may temporarily lodge in the air duct runs and the supply registers.
Any recirculated dust particles will be heated and charred by coming into contact with the heat exchanger.
This residue will soil ceilings, walls, drapes, carpets, furniture, and other household articles.
DISCONNECT THE ELECTRICAL POWER SUPPLY TO THE FURNACE BEFORE ATTEMPTING
ANY MAINTENANCE. FAILURE TO DO SO CAN CAUSE ELECTRICAL SHOCK RESULTING IN
Consult your installation contractor or service technician if you have any questions on instructions for removing
the air fi lter.
BE SURE THAT THE FILTER IS RE-INSTALLED WITH THE AIRFLOW DIRECTION
IDENTICAL TO ITS PREVIOUS USE. REVERSING THE FILTER WILL CAUSE DUST
TRAPPED WITHIN THE FILTER TO BREAK FREE AND RECIRCULATE WITHIN THE DUCT
4.2

LUBRICATION

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.

ROUTINE EXAMINATION

IMPORTANT:
We recommend that your furnace and exhaust/combustion air 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. Things
to check:
• Check the furnace for obvious signs of deterioration.
• Check the venting and combustion air piping to ensure that it is still fastened to the furnace. It should not
sag, and should have a 1/4" (6mm) per foot (305mm) slope upwards, to the outside wall or termination.
• There should be no water marks on the fl oor under the venting. Water marks may indicate a leaking pipe joint.
• All ductwork should be secured to the furnace, and all ductwork should be solidly supported throughout the
heating system.
