4.1 AIR
FILTER
H27.1
DO NOT OPERATE YOUR FURNACE OR AIR CONDITIONER FOR EXTENDED PERIODS OF
TIME WITHOUT AN AIR FILTER.
CAUTION
!
!
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.
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
SYSTEM.
CAUTION
!
!
H3.25.1
DISCONNECT THE ELECTRICAL POWER SUPPLY TO THE FURNACE BEFORE ATTEMPTING
ANY MAINTENANCE. FAILURE TO DO SO CAN CAUSE ELECTRICAL SHOCK RESULTING IN
PERSONAL INJURY OR LOSS OF LIFE.
WARNING

H27.3A
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.
•
The combustion air and exhaust terminals should be inspected occasionally to ensure that they are free of
obstructions and debris.
IMPORTANT:
We recommend that your furnace and exhaust/combustion air vents be checked by a quali
fi
ed
service technician once a year.
