NOTE: If thermostat terminals are jumpered at the time blower access door switch is closed, blower will run for 90 sec before beginning a heating or cooling cycle.

c.Perform component self-test as shown at the bottom of the SERVICE label, located on the front of blower access door.

d.Verify blower is rotating in the correct direction

16.If furnace is operating properly, RELEASE BLOWER ACCESS DOOR SWITCH. Remove any jumpers or re- connect any disconnected thermostat leads. Replace blower access door.

17.Downflow or horizontal furnaces with vent pipe through furnace only:

a.Install and connect short piece of vent pipe inside fur- nace to existing vent.

b.Connect vent connector to vent elbow.

18.Reinstall casing door.

19.Turn on gas supply and cycle furnace through one com- plete heating and cooling cycle. Verify the furnace temper- ature rise as shown in Adjustments Section. Adjust tem- perature rise as shown in Adjustments Section. If outdoor temperature is below 70_F, (21_C) turn off circuit breaker to outdoor unit before running furnace in the cooling cycle. Turn outdoor circuit breaker on after completing cooling cycle.

CLEANING HEAT EXCHANGER

The following steps should be performed by a qualified service agency:

NOTE: If the heat exchangers get a heavy accumulation of soot and carbon, they should be replaced rather than trying to clean them thoroughly. A heavy build-up of soot and carbon indicates that a problem exists which needs to be corrected, such as improper adjustment of manifold pressure, insufficient or poor quality combustion air, incorrect size or damaged manifold orifice( s), improper gas, or a restricted heat exchanger. Action must be taken to correct the problem.

If it becomes necessary to clean the heat exchangers because of dust or corrosion, proceed as follows:

1.Turn OFF gas and electrical power to furnace.

2.Remove outer access door.

3.Disconnect vent connector from furnace vent elbow.

4.For downflow or horizontal furnace having an internal vent pipe, remove internal vent pipe within the casing.

5.Disconnect wires to the following components. Mark wires to aid in reconnection of (be careful when discon- necting wires from switches because damage may occur):

a.Draft safeguard switch.

b.Inducer motor.

c.Pressure switch(es).

d.Limit overtemperature switch.

e.Gas valve.

f.Hot surface igniter.

g.Flame-sensing electrode.

h.Flame rollout switches.

i.Remove NOx baffles on low NOx models.

6.Remove screws that fasten the collector box assembly to the cell panel. Be careful not to damage the collector box.

Inducer assembly and elbow need not be removed from collector box.

7.Disconnect gas line from gas manifold.

8.Remove the 5 screws that attach the burner assembly to the cell panel. The gas valve and individual burners need not be removed from support assembly.

NOTE: Be very careful when removing burner assembly to avoid breaking igniter. See Fig. 46 and 47 for correct igniter location.

9.Using field-provided 25-caliber rifle cleaning brush, 36-in. (914 mm) long, 1/4 in. (6 mm) diameter steel spring cable, a variable speed, reversible electric drill, and vacuum cleaner, clean cells as follows:

a.Remove metal screw fitting from wire brush to allow insertion into cable.

b.Insert the twisted wire end of brush into end of spring cable, and crimp tight with crimping tool or crimp by striking with ball-peen hammer. TIGHTNESS IS VERY IMPORTANT.

NOTE: The materials needed in item 9 can usually be purchased at local hardware stores.

(1)Attach variable-speed, reversible drill to the end of spring cable (end opposite brush).

(2)Insert brush end of cable into the outlet opening of cell and slowly rotate with drill. DO NOT force cable. Gradually insert cable into upper pass of cell. (See Fig. 48.)

(3)Work cable in and out of cell 3 or 4 times to obtain sufficient cleaning. DO NOT pull cable with great force. Reverse drill and gradually work cable out.
