ABSTRACT:
A ceiling damper system that comprises a damper housing having an input opening to accept air from a heating, ventilation and air conditioning HVAC system, and an output opening to supply the HVAC air to a room. The system further comprises a damper mechanism to substantially block the flow of air through the damper housing when the temperature around the housing reaches a predetermined level. Two or more cross members are included, each of which is mounted between fixed points in the ceiling in a position to allow the cross members to support and hold the damper housing. The damper housing rests on the cross members and is mounted to the cross members. A method for mounting a ceiling damper that comprises providing a ceiling damper having a damper housing for accepting air from a HVAC system and providing the HVAC system air to a room. It further comprises mounting at least two cross members across fixed points in a room ceiling in a position to support the damper housing. It then comprises arranging the damper housing on the cross members so that the damper rests on the cross members and is affixed to the cross members in a position to provide HVAC air to the room. HVAC system air is then provided to the ceiling damper.
