INDUCED DRAFT AND CIRCULATOR BLOWER MOTORS

The bearings in the induced draft blower and circulator blower mo-

tors are permanently lubricated by the manufacturer. No further lu-

brication is required. Check motor windings for accumulation of dust

which may cause overheating. Clean as necessary.

FLAME SENSOR (QUALIFIED SERVICER ONLY)

Under some conditions, the fuel or air supply can create a nearly

invisible coating on the flame sensor. This coating acts as an insu-

lator causing a drop in the flame sense signal. If the flame 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 emery cloth or steel wool. Following cleaning, the

flame sense signal should be as indicated in the Specifications Sheet.

IGNITER (QUALIFIED SERVICER ONLY)

If the igniter and the surrounding air are at about 70°F and the igniter

wires are not connected to any other electrical components, the re-

sistance of the igniter should not exceed 200 ohms. If it does, the

igniter should be replaced.

FLUE PASSAGES (QUALIFIED SERVICER ONLY)

The heat exchanger flue passageways should be inspected at the

beginning of each heating season. If necessary, clean the passage-

ways as outlined below.

1. Shut off electric power and gas supply to the furnace.

2. Remove burner assembly by disconnecting the gas line and

removing the manifold brackets from the partition panel.

3. Remove the flue from the induced draft blower and the

collector box from the partition panel.

4. The primary heat exchanger tubes can be cleaned using a

round wire brush attached to a length of high grade stainless

steel cable, such as drain cleanout cable. Attach a variable

speed reversible drill to the other end of the spring cable.

Slowly rotate the cable with the drill and insert it into one of

the primary heat exchanger tubes. While reversing the drill,

work the cable in and out several times to obtain sufficient

cleaning. Use a large cable for the large tube, and then repeat

the operation with a small cable for the smaller tube. Repeat

for each tube.

5. When all heat exchanger tubes have been cleaned, replace

the parts in the reverse order in which they were removed.

6. To reduce the chances of repeated fouling of the heat

exchanger, perform the steps listed in Section XII, Start-up

Procedure and Adjustment.

WARNING

O PREVENT PERSONAL INJURY OR DEATH, DO NOT REMOVE ANY INTERNAL

COMPARTMENT COVERS OR ATTEMPT ANY ADJUSTMENT.

LECTRICAL

COMPONENTS ARE CONTAINED IN BOTH COMPARTMENTS.

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 ap-

pearance. Flames should be stable, quiet, soft and blue with slightly

orange tips. They should not be yellow. They should extend directly

outward from the burner ports without curling downward, floating or

lifting off the ports.

CLEANING (QUALIFIED SERVICER ONLY)

1. Shut off electric power and gas supply to the furnace.

2. Remove screws securing manifold to burner bracket. Slightly

pull manifold out and away from burner bracket. Burners will

drop. Re-secure manifold to burner bracket.

3. Tilt burners to slotted side of burner bracket. Rotate burners

clockwise to remove.

4. Use bottle brush to clean burner insert and inside of burner.

5. Replace burner (opposite of removal). Ensure burners are

fully seated on burner bracket tabs and are properly aligned.

6. Turn on electric power and gas supply to the furnace.

7. Check furnace for proper operation. Refer to “Operational

Checks” section to verify burner flame characteristics.
