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.
Fig. 26 Horizontal length requirement.
STEP 7
Apply high temperature sealant to 4" (100mm) and 7"
(175mm) collars or the termination one inch away from
crimped end. Guide the vent terminations 4" and 7" col-
lars into their respective vent pipes. Double check that
the vent pipes overlap the collars by 2" (50mm). Secure
the termination to the wall with screws provided and
caulk around the wall plate to weatherproof.
Support the horizontal pipes every 36" (914mm)
with metal pipe straps.
Check the fireplace to make sure that it is levelled
and properly positioned.
