I can see using those dampers on some chimneys. It also prevents the infiltration of cold air during down drafts. Dual safety switches on the gas vent dampers allow the burner to fire only when the damper is in the open position. You can unsubscribe at any time. The stops found in double-acting dampers should be removed if firing only with gas. This wastes money because the heat does not have time to transfer to the boiler. Since a major portion of gas flue products is water vapor, condensing can occur when the flue products are allowed to cool below dew point. Also, a vent damper could interfere with proper forced draft operation so it should not be installed on many newer furnaces. The building owners were forced to replace the double doors with large revolving doors in an effort to combat the buildings chimney effect. For dual rod installations, connect the flame sense wire from the burner/igniter to this terminal connector. A Category I vent system is typically vented with Type "B" vent materials. I supplied pics, help is greatly appreciated. The boiler requires a stable environment and the chimney is like the wild child.
