Abstract
The invention is concerned with a cooking range, especially suitable for mobile homes, which utilizes gas burners, where the exhaust gas draft is held substantially constant and the exhaust duct temperature is kept below a critical temperature by providing temperature-regulated cool air openings on the exhaust gas duct. Reliable regulation is accomplished by closures controlled by bimetallic springs positioned in a swivelable manner in the cool air openings so as to act on the closure flaps, and the closure action further improved by restoring springs exerting pressure on the outside of the closures.
