efficient, satisfactory service. However, the varied air
pollutants commonly found in most areas can affect
longevity and safety. Chemicals contained in everyday
household items such as laundry detergents, cleaning
sprays, hair sprays, deodorizers, and other products
which produce airborne residuals may have an adverse
effect upon the metals used to construct your appliance.
The cabinet of the furnace can be cleaned with soap and
water. Grease spots can be removed with a household
cleaning agent.
It is important that you conduct periodic physical
inspections of your appliance, paying special attention
to the gas burner and the flue outlet from the furnace.
These components are located at the front of the unit. A
flashlight will be useful for these inspections. Make one
inspection prior to the beginning of the heating season
and another during the middle.
Should you observe unusual amounts of any of the
following conditions, it is important that you call your
authorized dealer at once to obtain a qualified service
inspection:
• Rust, flakes, or other deposits
• Coatings
• Corrosion
Even if no unusual rust or other conditions are observed,
it is recommended that the furnace be inspected
and serviced at least once per year by a qualified
service technician.
Regular inspections and planned
maintenance will assure many years of economic
performance from your gas furnace.
14.1 CLEANING/REPLACING THE
FILTER
It is very important to clean or replace the air filter
regularly.
Dirty filters are the most common cause of inadequate
heating or cooling performance and can sharply increase
the operational costs of your unit. In some cases, they
can double the cost. The air filter should be inspected at
least every 6 weeks and cleaned or replaced as required.
Your furnace may use either a disposable filter or a
cleanable filter. The type of filter may be indicated on
a label attached to the filter.
If a disposable filter is
used, replace with the same type and size. To remove
excess dirt from a cleanable filter, shake filter and/or use
a vacuum cleaner. Wash filter in soap or detergent water
and replace after filter is dry.
Cleanable filters do not need to be oiled after washing.
Cleanable filters may be replaced with disposable filters.
If your air distribution system has a central return air filter-
grille, the furnace does not need a filter. Filter-grilles can
be maintained the same way as cleanable filters.
14.2 CONDENSATE COLLECTION
AND DISPOSAL SYSTEM
The condensate system must not be exposed to
temperatures under 32°F.
Make sure the condensate drain line does not become
blocked or plugged. Visual inspection of condensate flow
can easily be made while the furnace is operating. Use
a flashlight to illuminate discharge end of the condensate
drain that is placed in the sewer opening. The furnace will
not operate properly if condensate drain line becomes
blocked or plugged. If this event occurs, have the furnace
inspected by a qualified service technician.
14.3 ROLLOUT SWITCH
This unit is equipped with a manual reset high
temperature sensor or rollout switch.
In the unlikely
event of a sustained burner flame rollout, the rollout
switch will shut off the flow of gas by closing the gas
valve. The switch is located inside the gas burner area.
Flame rollout can be caused by blockage of the power
vent system, a blocked heat exchanger, or improper gas
pressure or adjustment. If this event occurs, the unit will
not operate properly. The gas supply to the unit should
be shut off and no attempt should be made to place it in
operation. The system should be inspected by a qualified
service technician.
14.4 SAFETY INTERLOCK SWITCH
The blower compartment door on your high efficiency gas
furnace is equipped with a safety interlock switch that will
automatically shut off your complete system (including
blower) once the door is removed.
This is for your
personal safety. Be sure to check your furnace for proper
operation once the door or panel has been replaced. If
the system does not operate once the panel has been
replaced, try removing and replacing it once again. If the
furnace still does not operate, call your dealer for service.
