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 ef
fi
ciency.
Some paper media high ef
fi
ciency
fi
lters, sometimes identi
fi
ed as HEPA
fi
lters can do an effective 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 suf
fi
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.
