All installations and services must be performed by qualified service personnel.

Reassemble the furnace to its original construction. Remount the burner being certain that the air tube is properly inserted into the chamber opening (see Burner Installation section).

VI. TROUBLESHOOTING

For troubleshooting the power gas burner, reference the burner manufactures instructions.

If the burner is producing an excessive combustion sound level, perform the following procedures:

1.Re-check the position of the burner tube to assure that the end of the tube is 1/4 inch in from the inside surface of the combustion chamber. Also, make sure the burner is firing squarely into the center of the combustion chamber.

2.Verify the correct burner air setting using instrumentation (see initial start up section). If the air setting on the burner is excessive, this will cause the combustion sound level to be louder than normal.

3.Move the draft control as close to the chimney as possible. Also, face the draft control towards the open area of the room.

4.Alter manifold pressure of the burner, but stay within normal operating pressures as specified by burner manufactures instructions.

5.Derate the input of the burner 10% from normal furnace input rate.

6.If the combustion sound is resonating through a particular portion of the ductwork, insulating the ductwork or using flex duct should isolate that portion of the ductwork.

If the furnace air blower will not come on or cycles abnormally, check the following:

1.If the blower motor is receiving 115 V, it has cutout on thermal overload or is defective. A belt that is very tight may cause the blower motor to cut out on thermal overload on a belt drive blower. An incorrect or faulty capacitor may prevent a direct drive blower motor from operating.

2.If the blower motor is not receiving 115 V, check the power source to the furnace, as well as all wire connections in the vestibule junction box. Check wire connections at the fan and limit and the fan temperature settings. Also, check the fan and limit for response to temperature.
