A return air filter is not supplied with this furnace; however, there
must be a means of filtering all of the return air. The installer will
supply filter(s) at the time of installation.

Improper filter maintenance is the most common cause of inad-
equate heating or cooling performance. Filters should be cleaned
(permanent) or replaced (disposable) every two months or as re-
quired.

MAINTENANCE
Become familiar with filter location and procedures for removal,
cleaning and replacing them. If help is needed, contact the in-

ILTER EMOVAL
Depending on the installation, differing filter arrangements can
be applied. Filters can be installed in either the central return
register or a side panel external filter rack (upflow only). A media
air filter or electronic air cleaner can be used as an alternate
filter. Follow the filter sizes given in the Recommended Minimum
Filter size table or instruction provided by the media or electronic
air cleaner manufacturer to ensure proper unit performance.
To remove filters from an external filter rack in an upright upflow
installation, follow the directions provided with external filter
rack kit. For further details, see your distributor.

NDUCED RAFT AND IRCULATOR
The bearings in the induced draft blower and circulator blower
motors are permanently lubricated by the manufacturer. No fur-
ther lubrication is required. Check motor windings for accumula-
tion of dust which may cause overheating. Clean as necessary.

LAME ENSOR
Under some conditions, the fuel or air supply can create a nearly
invisible coating on the flame sensor. This coating acts as an
insulator causing a drop in the flame sense signal. If the flame
EVER
sense signal drops too low the furnace will not sense flame and
will lock out. The flame sensor should be carefully cleaned by a
qualified servicer using steel wool. The flame sense signal should
be 1 to 3 microamps.

GNITER UALIFIED
At room temperature, the igniter ohm reading should be from 37 -
68 ohms.

ONTACT A QUALIFIED SERVICE AGENT AT ONCE IF AN ABNORMAL
FLAME APPEARANCE SHOULD DEVELOP
Periodically during the heating season, make a visual check of the
burner flames. Turn the furnace on at the thermostat. Wait a few
minutes, since any dislodged dust will alter the normal flame
appearance. Flames should be stable, quiet, soft and blue with
slightly orange tips. They should not be yellow. They should ex-
tend directly outward from the burner ports without curling down-
ward, floating or lifting off the ports.
C (Q
LEANING
1. Shut off electric power and gas supply to the furnace.
2. Disconnect the rollout limit wires, flame sensor wire, and
disconnect the igniter plug.
