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
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.
•
Water should fl ow easily through the condensate drain line. You may be able to observe this while the
furnace is operating if your condensate drain line from the drain trap assembly terminates at a fl oor drain
or sump pit. If clear plastic was used, it may yellow with age; however, the contents should be reasonably
clear. Excess debris in the drain line may indicate a problem which should be referred to your service
contractor. If the drain lines are opaque, your service technician will check them during the annual
servicing.
•
The gas burner should be observed from time to time during the heating season to ensure that the fl ames
are clean and blue. A bit of orange color in the fl ame is not likely to be a problem and is probably dust
particles burning. If you observe lazy yellow fl ames, call your heating or service contractor immediately.
The yellow fl ames inevitably lead to soot-ups.
