1.When the boiler is off, check that the vent damper position indicator points to the closed position. (See figure below.)
2.Turn the thermostat or controller up to call for heat and check that the vent damper indicator points to the open position. (See figure below.)
3.Turn the thermostat or controller down again and check that the vent damper position indicator returns to the closed position.
NOTE: 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.
