OPERATION
When the boiler 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. When properly installed, the electrical circuits
in this product are designed not to override the existing limit and safety controls of the appliance.
WARNING: Before installing the vent damper:
1. Read this manual carefully and completely.
2. Be sure to follow all procedures and safety inspections.
3. Do not negate the action of any safety or operational controls.
4. The vent damper is not for retrofit in Canada.
TO THE USER
For continued safe operation the appliance device combination 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 and during each heating season.
