Abstract
A door with a gas burner on an inner surface and a system for carrying a combustible gas to the burner on the outer surface thereof. The door comprises a pair of metal sheets rigidly connected to one another at the edges thereof, each sheet having input and output openings for the gas mixture that are mutually separated in order to leave an inner space receiving a deflector plate serving as a thermal shield to be swept over on either side by the flow of the gas mixture supplying the burner. This arrangement reduces heat loss through the door; thus, keeping the outer surface cold, avoiding the risk of burns, and preheating the gas mixture. The invention can be used in heating appliances.
