VENT DAMPER OPERATION

For safe, efficient operation, the vent damper and all flue-product-carrying areas of the appliance must be checked annually, with particular attention given to deterioration from corrosion or other sources.

Check vent damper operation as follows:

1. When the boiler is off, check that the vent damper position indicator points to the closed position, below.

3.Turn the thermostat or controller down again and check that the vent damper position indicator returns to the closed position.

THE VENT DAMPER MUST BE INSPECTED AT LEAST ONCE A YEAR BY A TRAINED, EXPERIENCED

SERVICE TECHNICIAN. THE NAME OF THE PERSON WHO ORIGINALLY INSTALLED YOUR VENT DAMPER IS SHOWN ON THE INSTALLATION LABEL. DAMPER MUST BE IN OPEN POSITION WHEN BOILER MAIN BURNERS ARE OPERATING.
