1. Locate and cut the vent opening in the wall. For
combustible walls first frame in opening. Rear vent no elbows
Combustible walls: Cut a 11Z\x"H x 9Z\x" W (9 x
2/99 djt
41 mm) hole through the exterior wall and frame as
shown. Figure 18
Noncombustible walls: Hole opening should be 7Z\x"
(190 mm) in diameter.
. 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. Figure 19
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 11Z\x"H x 9Z\x"W
(9 x 41 mm) rectangle hole (for noncombustible
material such as masonry block or concrete, a 7Z\x"
[190 mm] diameter hole is acceptable). Figure 18.
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 11Z\x"x9Z\x" rectangle hole
through combustible exterior wall (7Z\x" diameter hole
if noncombustible). Frame as necessary. Allow 1/4"
minimum rise per foot. Figure 18
