Gravity furnace efficiency
Webcloses the gas valve if the furnace over-heats In a conventional natural draft gas furnace, the hot flue gasses are: vented by natural convection uses a special product called silicon carbide, is usually operated off 120 volts, is energized for only a short period of time during start-up Hot surface ignition WebDec 10, 2005 · We have an older Class B with a gravity furnace. It is great. Quiet. It has a standing pilot light and the thermostat is a little tricky to keep from getting the place too hot. It is a mechanical one beside the controls, not a remote on on the wall. It uses a heat exchanger to vent the combustion gas outside.
