| Installation Guide: | Where the vent passes through a floor or ceiling without support, a Firestop Spacer must be used on both sides of the penetration to provide a barrier to fire and maintain a minimum 50mm (2in) air gap clearance to combustible materials. If the Gas Vent is required to be supported where it penetrates the floor/ceiling Support Plates should be applied. These square heavy gauge galvanised plates must be fixed through the corner holes on top of the floor joist or slab through which the chimney is passing. The flanged collar is clamped to the vent so that the lower flange rests on the support plate. A Firestop Spacer must be used on the underside of the opening at ceiling level. The MAXIMUM height that can be supported, including any suspended lengths, is 18m (60ft). The combination of lengths and fittings used should be such that no joint occurs within the floor space. |
