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.
21)
Sealing vent pipe and firestop gaps with
high temperature sealant will restrict
cold air being drawn in around fireplace.

STEP 3
Place fireplace into position. (Fig. 19) Measure the
vertical height (X) required from the base of the flue
collars to the center of the wall opening.
STEP 4
Apply a bead of high temperature sealant to the inner
and outer flue collars of the fireplace and using appro-
priate venting component(s) attach to fireplace with
three (3) screws. (Fig. 20) Follow with the installation
of the inner and outer elbow. Again secure joints with
three (3) sheet metal screws. Wipe off any excess high
temperature sealant.
STEP 5
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-
ing a second 90
°
elbow). (Fig. 20)
Always install horizontal venting on a
level plane.
