Measure the horizontal length requirement including a
2" (51mm) overlap, ie from the elbow to the outside wall
face plus 2" (51mm) (or the distance required if install-

STEP 6
Use appropriate length of pipe sections - telescopic or
fixed - and install the horizontal vent sections. The
sections which go through the wall are packaged with
the starter kit, and can be cut to suit if necessary. (Fig.

Sealing vent pipe and firestop gaps with
high temperature sealant will restrict
cold air being drawn in around fireplace.
