If this action does not reactivate the unit, contact a qualified service agency for assistance.

In general, if the thermostat is set in the heating mode, the heating system functions entirely automatically. However, under certain circumstances, the appliance may not be able to fire the burner. For instance, if the manual oil shutoff valve has been closed or the oil tank is out of fuel, the oil line may have air trapped in it. It will be necessary to purge the air by bleeding the supply line from the tank to the burner again for the heating system to operate. Refer to the instructions under the Extended Appliance Shutdown section of this manual.

NOTICE: Thermo Products recommends that the user/homeowner, contact a qualified service agency for assistance in bleeding the fuel line(s) and lighting off the heating section.

The following maintenance points should be reviewed periodically to assure the heating and cooling systems continue to function properly.

: Shut off unit and disconnect the power source before disassembling the unit.

: Never operate the appliance without clean air filters in place.

: This appliance requires air for combustion, ventilation, and cooling. Do not block or obstruct air openings in the unit and the air space around the perimeter of the unit.

1.At least every three months, under normal usage conditions, check and clean all air filters in the appliance and, if present, in the duct system. If excessively dirty air filters are not cleaned, or changed, poor system performance will result due to reduced airflow. Low airflow places unnecessary strain on the compressor, possibly causing the system to shutdown on the refrigerant high-pressure switch. Refer to Figure 14 for a sketch of the filter location.

2.Do not allow the fuel oil tank to run completely empty. During the summer, keep the tank full to reduce condensation of moisture on the inside surface of the tank. If the fuel tank runs completely dry, it may be necessary to bleed air from the fuel lines. Contact a qualified heating contractor to bleed the lines and restart the burner.

3.Check the supply and return air connections to the appliance to insure the seals between the duct and appliance and the appliance and home are intact. Check the ducts for any signs of collapse, holes, or excessive corrosion. Repair or replace components as required.
