Abstract
An appliance for burning a combustible gas, for example a liquefied petroleum gas. The appliance includes a relatively massive metal body forming a heat sink, in which there is formed a passage for flow of the combustible gas from a feed inlet to a discharge outlet. A control member controls the flow rate of the combustible gas. A mixing member for mixes primary air in with a stream of the combustible gas in a gaseous phase in order to obtained a mixture that can be burned. A burner burns the mixture to be burned, and is in thermal connection with the metal body. The control member includes a pressure reducer, at least partially incorporated into the metal body. The pressure reducer includes a chamber into which the combustible gas is admitted in a liquid phase at high pressure, and a chamber from which the gas is discharged at low pressure, at least partially in the gaseous phase. The chambers are formed in the metal body. The pressure reducer also includes a valve situated for the most part within the metal body.
