Fixed straight pipes are available in three lengths: 1000mm, 500mm and 330mm. Distance to combustible materials: 50mm.
Vent pipe lengths and fittings must be installed with the male coupler upwards and female coupler downwards, fitting over the male. Make sure that the joining ends are round and undamaged, if any component is out of round, hand manipulation to correct the shape is recommended before attempting to fit the components.
Gas Vent lengths and fittings are available with the outer casing fabricated from galvanised steel. The flue liner is aluminium. Vertical seams are rolled and securely locked. The inner and outer casing are joined at one end only and a 6mm (1/4") air gap is incorporated: the inner liner is thus free to expand as the temperature changes in the vent.
