be supported every three feet
(914mm). Use wall straps for this
purpose.

REAR WALL VENT INSTALLATION
When installed as a rear vent unit this appliance may be vented directly to a termination located on the rear wall behind
the appliance
•
The maximum horizontal distance between the rear of the appliance and the outside of termination is 20" (508
mm
).
See
Figure 11.
•
Only one 60° elbow is allowed in these installations.
VENTING INSTALLATION
1. Locate and cut the vent opening in the wall. For com-
bustible walls first frame in opening.
See Figure 11.
Combustible Walls:
Cut a
9
"H x 9" W
(
229mm x 229mm
) hole through the exterior wall
and frame as shown.
See Figure 12.
Noncombustible Walls:
Hole opening should be
7
1
⁄
2
" (190mm) in diameter.
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 13.
3. Attach vent pipe assembly to the fireplace. Set fire-
place in front of its permanent location to insure
minimum clearances. Mark the wall for a
9
"H
x 9"W (2
29mm x 229
mm) rectangle hole (for
noncombustible material such as masonry block or
concrete, a 7
1
/
2
" [190mm] diameter hole is accept-
able).
See Figure 11.
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
9
"x9" (
229mm x 229
mm) rectangle hole through combustible
exterior wall (7
1
/
2
" [190mm] diameter hole if noncombustible). Frame as necessary. Allow
1
/
4
" minimum rise per foot.
See
Figure 12.
