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.
