OPERATION

When the oil heating appliance receives a call for heat, the damper rotates to the open position before the burner circuit is
energized. If the damper does not rotate to the open position, the burner circuit will not be energized and will not allow the
burner to fire. When the call for heat is satisfied the damper will remain open for approximately 3 minutes to allow the residual
flue gases to escape before closing. When properly installed, the electrical circuits in this product are designed not to override
the existing limit and safety controls of the appliance.
TO THE USER
For continued safe operation, the heating appliance should be inspected annually by a qualified service agency. It is
recommended that the homeowner should have the vent system and the damper device examined annually for deterioration
from corrosion or other sources. This inspection should be performed prior to each heating season.
