MAINTENANCE OF YOUR FURNACE
Always shut off all power to the unit before attempting
any of the following maintenance procedures. Failure
to do so may result in personal injury.
There are routine maintenance steps you should take to keep
your furnace operating efficiently. This maintenance will
assure longer life, lower operating costs, and fewer service
calls. In addition to the maintenance procedures listed in
this manual, there are also other service and maintenance
procedures that require the skills of a service person who has
specialized tools and training. Personal injury can result if
you are not qualified to do this work. Please call your dealer
when service is needed.
Your gas furnace is designed to give many years of 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 affect 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 economical performance from your
gas furnace.
Combustion and Ventilation Air
Adequate air supply must be provided to furnaces located in a
closet, alcove, or utility room by means of upper and lower
