Troubleshooting

General

This section contains information for locating and correcting most operating problems. This manual can not list all that may occur. When performing trouble shooting procedures, follow all warnings and safety procedures. At no time does this manual supercede good common sense.

Sequence of Operation

1.Move main switch to HEAT. The green standby LED should illuminate

2.Rotate the room thermo to the nine o'clock position or until the green HEAT LED illuminates.

3.After a five second delay the burner system will come on. This includes the ignition transformer, fuel pump, fuel solenoid, and combustion blower.

4.The vent fan will come on when the heat exchanger comes up to temperature and the flame switch closes. The amount of time will vary (30 to 120 seconds) depending on the ambient temperature.

5.Once the vent fan comes on the heater will continue to operate until the call for heat from the room thermo is satisfied or the main switch is turned off. If the airflow is reduced due to very high back pressure, the burner will cycle off from time to time. This is normal.
