V. COMBUSTION-AIR BLOWER

Clean periodically to assure proper air¯ow and heating effi- ciency. Inspect blower wheel every fall and periodically dur- ing heating season. For the ®rst heating season, inspect blower wheel bimonthly to determine proper cleaning frequency.

To inspect blower wheel, remove draft hood assembly. Shine a ¯ashlight into opening to inspect wheel. If cleaning is re- quired, remove motor and wheel as follows:

1.Remove burner access panel. (See Fig. 35.)

2.Remove the 7 screws that attach induced-draft motor mounting plate to blower housing. (See Fig. 34.)

3.Slide the motor and blower wheel assembly out of the blower housing. (See Fig. 36.) Clean the blower wheel. If additional cleaning is required, continue with Steps 4 and 5.

4.To remove blower, remove 2 setscrews. (See Fig. 36.)

VI. LIMIT SWITCH

Remove blower panel. Limit switch is located on the gas partition.

VII. BURNER IGNITION

Unit is equipped with a direct spark ignition 100% lockout system. Ignition module is located in the control box. Module contains a self-diagnostic LED. During servicing, refer to la- bel diagram for LED interpretation.

If lockout occurs, unit may be reset by either momentarily interrupting power supply to unit, or turning selector switch to OFF position at the thermostat.

VIII. MAIN BURNERS

At the beginning of each heating season, inspect for deterio- ration or blockage due to corrosion or other causes. Observe the main burner ¯ames and adjust if necessary.

CAUTION: When servicing gas train, do not hit or plug ori®ce spuds.

A.Removal of Gas Train

1.Shut off manual gas valve.

2.Shut off power to unit.

3.Remove burner access panel. (See Fig. 35.)

4.Disconnect gas piping at unit gas valve.

5.Remove wires connected to gas valve. Mark each wire.

6.Remove ignitor and sensor wires at the ignitor module.

7.Remove the mounting screw that attaches the burner rack to the basepan. (See Fig. 34.)

8.Slide the burner rack out of the unit. (See Fig. 34 and 37.)

9.To reinstall, reverse the procedure outlined above.
