H23.2
The air fi lter should be inspected frequently and cleaned or replaced as necessary. We recommend a monthly
inspection at fi rst, perhaps coinciding with the arrival of the monthly fuel bill as a reminder. The frequency may
be increased or decreased depending on experience and conditions.
Dirty fi lters result in higher than normal operating temperatures, reduced air fl ow and lower e
ffi
ciency.
Some paper media high e
ffi
ciency fi lters, sometimes identifi ed as HEPA fi lters can do an e
ff
ective and
excellent fi ltration of the air; however, some models may also cause a large pressure drop across the fi lter. The
contractor should assess the capabilities of the duct system to deliver su
ffi
cient air fl ow if this type of fi lter is
considered.
RECOMMENDED: Electronic air cleaners using electrostatic precipitation to remove dust are an excellent fi ltration
device when used in conjunction with a pre-fi lter. A 16”
x 25” (406mm x 635mm) model is an ideal fi t with this
furnace in the case of a side mounted return air inlet. The
integrated furnace control is supplied with an electrical
terminal for use with electronic air cleaners.
NOTE
If two return air inlets are used, both must be equipped
with fi lters.
DO NOT OPERATE THE FURNACE FOR PROLONGED PERIODS OF TIME WITHOUT AN
AIR FILTER.
A PORTION OF THE DUST ENTRAINED IN THE AIR MAY LODGE IN THE SUPPLY AIR
DUCTWORK AND REGISTERS. ANY RECIRCULATED DUST PARTICLES WILL BE HEATED
AND CHARRED BY CONTACT WITH THE FURNACE HEAT EXCHANGER. THIS RESIDUE
WILL SOIL CEILINGS, WALLS, DRAPERY, CARPETS, AND OTHER HOUSEHOLD ARTICLES.
CAUTION

H23.2.3
Both the exhauster motor and circulating fan motor are sealed bearing type motors. Neither requires routine
lubrication. Excess lubrication will void the warranty, shorten the service life of the motors, and will attract the
buildup of dust and dirt.
