[origin: EP0672866A2] The adaptor (10) is pushed into the flue conduit (12) with the largest cross-section and has an opening for insertion of the flue conduit with the smaller cross-section, an inner seal for location on the outer walling of this flue conduit with the smaller cross-section, an inner seal for location on the outer walling of this flue conduit and an outer seal (22) for location on the inner walling of the conduit with the larger cross-section. The seals (22,30) are of elastic temp.-resistant material. The adaptor has a disc-shaped, shape-resistant support body (16) of temp.-resistant material with a through passage aperture (28) for the flue conduit. The inner seal (30) has a smaller through passage aperture (32) arranged in the through passage aperture (28) of the support body (16).
