Abstract
A gas burning furnace is disclosed with a sealed and vented gas control valve. Sealing the gas control valve in an enclosure shields the control valve from the external environment. By venting the enclosure to the furnace pilot light, any gas leaking from the gas control valve into the enclosure is conducted to and ignited by the pilot light in a deliberate controlled manner, thereby precluding an explosion in the enclosure. Other safety features disclosed include an overheat shut-off, pilot light extinguished shut-off and blower malfunction shut-off.
