6.D KEEP AIR FILTER(S) CLEAN
As a user, your personal responsibility is to
keep air filter(s) clean.
1. During the first four weeks after your
furnace is installed, inspect your air filter(s)
for dirt every week. Then check the filters
monthly and replace as necessary.
2. If the filter(s) is of a washable type, clean
filter(s) according to the manufacturer’s
specifications.
6.E DO NOT OBSTRUCT DUCT WORK
For proper operation, keep registers and return
air grilles open. Do not cover or block them
with rugs, carpets, drapes or furniture.
6.F HAVE YOUR FURNACE CHECKED
ANNUALLY
The furnace, vent terminal, and the combustion
air intake hood should be inspected yearly by a
qualified service agency, generally prior to the
heating season. Detailed procedures for this
inspection are contained in the instructions
booklet and should be handled by the qualified
service agency only.
A general inspection of the furnace, the furnace
area and the vent terminal should be conducted
on a regular basis by the owner/occupant. This
review should include:
1. Make sure the furnace always has the
minimum clearance as detailed on the
furnace rating plate. Special attention must
be given to these items if any remodeling is
done.
2. Make sure the vent terminal is in place and
is physically sound.
3. Reviewing that the return air duct
connection(s) is physically sound, is sealed
to the furnace casing.
4. The physical support of the furnace is
sound without sagging, cracks, gaps, etc.
around the unit so as to provide a seal
between the unit and the structure.
5. Inspect for any obvious signs of
deterioration of the furnace.
6. Periodic examinations of the vent terminal
should also be conducted by the owner on a
regular basis, preferably every month but
at least every two months during the heating
season.
7. Check the entire vent terminal for any
blockage. If any debris is present remove it.
6.G THE FOLLOWING PROCEDURE SHOULD
BE FOLLOWED FOR THE PERIODIC
INSPECTION AS CONDUCTED BY THE
OWNER/OCCUPANT.
1. Set the wall thermostat to the OFF position
or lower the set point lever to a temperature
well below the existing room temperature.
Shut off electric power to the furnace. A
circuit breaker is located behind the lower,
small access panel on the right side.
2. Remove the burner access door. See
Figure 4.
3. Use flashlight or trouble light to observe the
burner compartment and burners. There
should be very minimal scaling or sooting
in this area. Any loose debris may be
vacuumed out. Also observe the sides of
the heat exchanger tubes for “hot spots” due
to improper burner alignment or overfiring
and give particular attention to any area
where it looks like there may be any
deterioration from corrosion or rusting.
Observe for any corrosion on the burners
themselves. Should anything appear
questionable, contact your service agency.
4. Inspect the vent terminal, or vent system
observing for any debris from weather,
birds, and the like. Clean if necessary.
Also check the combustion air inlet hood to
make sure it is clear. See Figure 4.
CAUTION
A dirty air filter(s) reduces system
efficiency and can cause erratic control
performance. These could result in
damage to blower motor or heat
exchanger.
WARNING
After cleaning or changing filter(s), filter
access must be closed and latched.
Failure to do so could cause nausea,
asphyxiation, or fire resulting in damage,
injury or death.
