The invention is concerned with the construction in a domestic dwelling of the prefabricated type of a class 1 flue system. Conventionally in a prefabricated home, the class 1 flue system is connected to either a frame or prefabricated panels of the prefabricated home. Instead of adopting the conventional practice of fixing the due blocks to the frame or panels, (which results in stress on the flue and/or the frame or panels when as is usual, the frame or panels shrink), intermediate U sectioned channels 50 are provided, with the open sides facing the flue blocks 36. The edges of the blocks simply locate in the channels, but are not fixed thereto, so that stress on the flue as a result of shrinkage of the frame or panels is avoided. |
