Abstract Of The Disclosure A vent control arrangement for energy conservation having bimetallic damper elements mounted in a draft hood which forms an integral part of the heating apparatus. The bimetallic elements open and close the flow passage for vent gases from the combustion apparatus in response to temperature change. The vent control arrangement is designed for minimum resistance to the flow of vent gases when installed in the integral draft hood. A design without friction surfaces and without transfer of movements or signals between components is used. Opening time is minimized by closeness to the heat source and in one embodiment by alternate bimetal reeds of different initial tension, in other embodiments by alternate orientation, or by different flexivity of alternate bimetal reeds.
