Abstract: The invention relates to an insert for an exhaust manifold of a heat exchanger device for a cooking appliance comprising a support for two or more pipe sockets having at least one expansion slit, a first cover for the at least one expansion slit on the support, an insulation comprising a support insulation on the first cover and a pipe socket insulation around at least a portion of the pipe socket, and a second cover at least on the pipe socket insulation. It further relates to an exhaust manifold with such an insert, a heat exchanger device with such an exhaust manifold, and a cooking appliance with such a heat exchanger device.

Abstract: The disclosure relates to a pore burner, especially for cooking appliances, including a housing provided with at least one inlet for a gas/air mixture as a fuel and/or at least one inlet for air and/or at least one inlet for gas and/or at least one outlet for air and/or gas and/or waste gases. The housing includes at least one dimensionally stable, porous molded body formed of sintered metallic powder and/or pressed metallic wire mesh, on the surface of which and/or in the pore spaces of which are reaction zones for the flame development for forming a surface burner.

Abstract: A method of adjusting at least one parameter of gas-operated cooking equipment as a function of the site and/or of the height of the site of the cooking equipment includes determining the geodetic height at the site during an initialization step by determining at least one physical parameter or a difference of two physical parameters and adjusting the heat output of at least one combustion system of the cooking equipment. The determined physical parameter may be air pressure, density, the mean ambient temperature, the humidity in the air and/or the boiling point of water and the physical parameter or the difference of the two physical parameters may be determined by starting up at least one functional group of the cooking equipment. The adjustment of the heat output of the combustion system of the cooking equipment may be performed by adjusting the air/fuel mixture in the region of an ignition device of the combustion system.

Abstract: A combustion system and a method for adapting the combustion system to utilize a first fuel when the system has been designed for a second fuel. The method and system provide inlets for adding air to lower the quality of the first fuel to the quality of the second fuel or inlets for adding a third fuel of a higher quality than the second fuel to raise the quality of the first fuel to the level of the quality of the second fuel.
