STEP 5
Measure the horizontal length requirement including a
2” (51 mm) overlap, i.e. from the elbow to the outside
wall face plus 2” (51 mm) (or the distance required if
installing a second 90° elbow. (Fig. 26)
Always install horizontal venting on a level
plane.
STEP 6
Use appropriate length of pipe sections - telescopic or
fixed and install. The section which goes through the
wall is packaged with the starter kit, and can be cut to
suit if necessary.
Sealing vent pipe and firestop gaps with high tem-
perature sealant will restrict cold air being drawn in
around fireplace.
