ENERVEX ADM AUTOMATIC DAMPERProduct Information Use The ADM Automatic Damper is a single blade, two position damper powered by an actuator. It is used to balance draft in a boiler connector and to reduce boiler stand-by losses. It is for installation with gas-fired or oil-fired equipment only. Description The ADM Automatic Damper is powered by a 120VAC or 24VAC/ VDC actuator. The actuator is equipped with a fail safe system to open the damper in the event of an electrical or mechanical failure. It has an adjustable NO/NC endswitch to provide damper position open/closed. The ADM is available in standard stack diameters ranging from 6 to 36 inches. The actuator interlocks with a gas or oil fired heating appliance to open the damper when the appliance is in use, and closes it when the appliance is not in use. The ADM damper is manufactured with slip connections to connect to chimneys without flange connections. The ADM is rated for temperatures up to 1400oF (760oC). The ADM should be installed with sufficient clearance above the boiler outlet to allow for damper protrusion into the stack when fully open. Material The frame is made of 20 GA 316L stainless steel. The blade is made of 18 GA 316L stainless steel.
