STEP 4
Attach the appropriate venting component(s) to the
inner and outer flue collars of the fireplace using three
(3) screws. (Fig. 24) Follow with the installation of the
inner and outer elbow. Again secure joints with three (3)
sheet metal screws.
STEP 5
Measure the horizontal length requirement including
a 2” (51 mm) overlap, ie from the elbow to the outside
wall face plus 2” (51 mm) (or the distance required if
installing a second 90° elbow). (Fig. 24)
Always install horizontal venting on a level
plane.

tions.
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 pack-
aged with the starter kit,
and can be cut to suit if
necessary. (Fig. 25)
Sealing vent
pipe and
firestop gaps
with high tem-
perature seal-
ant will restrict
cold air being
drawn in around
fireplace.
STEP 7
Guide the vent terminations 4” and 7” collars into their
respective vent pipes. Double check that the vent pipes
overlap the collars by 2” (51 mm). Secure the termina-
tion to the wall with screws provided and caulk around
the wall plate to weatherproof. (Fig. 26) As an alterna-
tive to screwing the termination directly to the wall you
may also use expanding plugs or an approved exterior
construction adhesive. You may also attach the termi-
nation with screws through the inner body into the 4”
(102 mm) vent pipe however for this method you must
extend the 4” (102 mm) pipe approximately 6” (152
mm) beyond the outer face of the wall.
