Example:
Elbow 1 = 90°
Elbow 2 = 45°
Elbow 3 = 45°
Elbow 4 = 90°
Total angular variation = 270°
1 + 2 + 3 + 4 = 270°

STEP 2
Place fireplace into position. (Fig. 49) Measure the vertical
height (X) required from the base of the flue collars to the
center of the wall opening.
STEP 3
Attach appropriate venting component(s) to the fireplace
with three (3) screws. (Fig. 50) Follow with the installation
of the inner and outer elbow. Again secure joints with three
(3) sheet metal screws.

STEP 4
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. 50)
Always install horizontal venting on a level
plane.
STEP 5
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. 48)
Sealing the gaps between the vent pipe and
firestop with high temperature sealant will
restrict cold air being drawn in around fire-
place.
STEP 6
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 termination
to the wall with screws provided and caulk around the
wall plate to weatherproof. (Fig. 52) As an alternative to
screwing the termination directly to the wall you may also
use expanding plugs or an approved exterior construc-
tion adhesive. You may also attach the termination 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.
Support horizontal pipes every 3’ (914 mm) with metal pipe
straps. Make sure the horizontal vent pipe is installed on
a level horizontal plane.
