1. Locate and cut the vent opening in the wall. For
combustible walls first frame in opening.
Combustible Walls:
x 24mm) hole through the exterior wall and frame as
shown. See Figure 20.

2. Rigid vent pipes and fittings have special twist-lock
connections. Assemble the desired combination of
pipe and elbows to the appliance adaptor with pipe
seams oriented towards the wall or floor.
Twist-lock Procedure: The female ends of the pipes
and fittings have three locking lugs (indentations).
These lugs will slide straight into matching slots on
the male end of adjacent pipes and fittings. Push the
pipe sections together and twist one section clockwise
approximately one-quarter turn until the sections are
fully locked. See Figure 21.
3. Attach vent pipe assembly to the fireplace. Set fire-
place in front of its permanent location to insure mini-
mum clearances. Mark the wall for a 11
(292mm x 24mm) rectangle hole (for noncombustible
material such as masonry block or concrete, a 7
[190mm] diameter hole is acceptable). See Figure
20. The center of the hole should line up with the
center line of the horizontal rigid vent pipe end. Be
sure to allow for minimum rise. Cut a 11
(292mm X 241mm) rectangle hole through com-
bustible exterior wall (7
if noncombustible). Frame as necessary. Allow
minimum rise per foot. See Figure 20.
