Abstract
A housing structure with a single pivoted damper member is provided as a replacement for the draft hood associated respectively with the flue outlet and vent pipe inlet in a gas heater system. The normal flue outlet for the gas system connects to a first passage in the housing and the normal overhead vent inlet connects to a second passage in the housing above the first passage. First ends of the passages adjacent to their connections to the flue outlet and vent pipe inlet are closed off and second ends open out in a common plane. Communicating with the second ends is an ambient atmosphere opening so that under conditions where the second ends of the passages are open, proper exhausting of gases passing up through the flue to the vent takes place. The single damper itself is mounted to swing in a manner to close off both passages simultaneously when in a first position and also isolate these passages from the ambient atmosphere inlet. In this first position, heat is retained in the heater as well as the room. When the damper member is swung to a second position, the ends of both passages are simultaneously opened so as to be in communication with each other as well as the ambient atmosphere opening.
