BS 715:2005

This standard is now limited to the manufacture of metal flue boxes. It gives requirements for the dimensions, material and performance of metal flue boxes that enable gas fire flues to be installed within a dwelling against or within a wall, which does not have a fireplace or flue. The performance of the flue boxes are tested through a strength test and a temperature test. The flue boxes specified are intended to be used with metal flue pipes conforming BS EN 1856-1 and BS EN 1856-2.
