Abstract (en)
[origin: EP0519313A2] Arrangement for guiding fresh air and waste gas, in particular for a wall-mounted gas appliance, in which a waste gas pipe is arranged essentially concentrically in a fresh air pipe passing through a wall, and in which an insulating pipe is provided, which overlaps the internally situated waste gas pipe and is held on the waste gas pipe. In order, in such an arrangement, to be able easily to adapt the individual parts to the respective requirements, it is envisaged that at least two distance rings (5) are pushed onto the waste gas pipe (3), between which the insulating pipe (4) is held. <IMAGE>
