T o cut the straight sections listed above refer to Figure 7.31 and the following instructions: a) Determine the required length of the outer pipe. When doing this allow an additional 1” of length for insertion into the female end of the adjoining pipe.
3) Joining Pipe - a) Start assembly of the vent system at the boiler . Lubricate the brown gasket in the boiler vent collar with a few drops of water .
4) 80/125mm Horizontal T erminal Installation - a) Cut a 5-1/2” diameter hole through the exterior wall at the planned location of the horizontal terminal. b) Measure distance “L” from the outside surface of the exterior wall to the end of the last fitting as shown in Figure 7.
