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 clean 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.
SECTION 6 • PROPER MAINTENANCE OF
YOUR FURNACE
You need special abilities, mechanical skills and tools to
maintain your furnace properly. If you are uncertain about
your abilities or if you lack proper skills or tools, do not try
to maintain or repair you furnace yourself. Instead, contact a
qualified installer, service agency or gas supplier.
