Device for mounting a gas heater on a wall for connection with the exterior

摘要

A device for mounting a gas-fired heating apparatus on a wall and connecting it through a flue for communication with the outside of the wall. The flue comprises inner and outer coaxial tubular members defining inner and outer conduits for carrying combustion supporting air from the exterior to the heating apparatus and combustion gases from the heating apparatus to the exterior. A register admitting combustion supporting air and venting combustion gases is fitted at the free end of the flue remote from the heating apparatus. A support plate has a circular aperture in a base for locating the support plate on the outer coaxial tubular member and wings cooperable with fittings on the heating apparatus for supporting the heating apparatus. A gasket with a retaining collar is received along a portion of the support plate and tightened on the outer coaxial tubular member.
