Use & Care Manual
MAINTENANCE
It is recommended for safety and
proper furnace operation that a
seasonal inspection and start-up be
performed. This should include your
furnace, supply ducts, return ducts,
e
lectrical supply, gas supply, drain and
vent system. This routine maintenance
must be performed by a qualified
HVAC professional, service agency or
the gas supplier.
TURN OFF ELECTRICAL POWER
TO THE FURNACE BEFORE
R
EMOVING PANELS. FAILURE TO
DO SO CAN RESULT IN
ELECTRICAL SHOCK, SEVERE
PERSONAL INJURY OR DEATH.
DO NOT OPERATE THE SYSTEM
WITHOUT FILTERS. A PORTION OF
THE DUST ENTRAINED IN THE AIR
MAY TEMPORARILY LODGE IN THE
DUCT RUNS AND AT THE SUPPLY
REGISTERS. ANY CIRCULATED
DUST PARTICLES COULD BE
HEATED AND CHARRED BY
CONTACT WITH THE FURNACE
HEAT EXCHANGER. THIS RESIDUE
COULD SOIL CEILINGS, WALLS,
DRAPES, CARPETS AND OTHER
ARTICLES IN THE HOUSE.
SOOT DAMAGE MAY OCCUR WITH
FILTERS IN PLACE. WHEN
CERTAIN TYPES OF CANDLES, OIL
LAMPS OR STANDING PILOTS ARE
BURNED.
FILTER MAINTENANCE
Have your qualified installer, service
agency or the gas supplier instruct you
on how to access your filters for
regular maintenance.
FILTERS
Filter application and placement are
critical to airflow, which may affect the
heating and cooling system
performance. Reduced airflow can
shorten the life of the system’s major
components, such as motor, limits,
heat exchanger, evaporator coil or
compressor. Consequently, we
recommend that the return air duct
system have only one filter location.
The most common location will be
inside the furnace or a filter base. For
systems with a return air filter grill or
multiple filter grills, can have a filter
installed at each of the return air
openings. Your HVAC professional can
show you where they have installed
the filter(s).
