<p>A combined flue-gas outlet/air supply coupling device for connecting a gas-fired heating device to a flue-gas outlet/air supply duct arranged in a wall comprises a substantially curved connection piece (5) which is guided slidably in the housing (2) of the heating device. An adaptor (4) can be coupled to that end of the connection piece (5) which faces the heating device, on the one hand, and to the flue-gas outlet and the air supply of the heating device, on the other hand. That end of the connection piece (5) which is remote from the heating device can be pushed onto the flue-gas outlet/air supply duct (3) in the manner of a sleeve. <IMAGE></p> |
