REAR (THROUGH THE WALL) APPLICATIONS
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).
Figure 19
• Only one 45° elbow is allowed in these installations.
VENTING INSTALLATION
1.
Locate and cut the vent opening in the wall. For
combustible walls first frame in opening.
Combustible Walls:
Cut a 11

" W hole
through the exterior wall
. Figure 20
Noncombustible Walls:
Hole opening should be

" (190 mm) in diameter.
2, Rigid vent pipes and fittings have special twist-lock
connections. Assemble the desired combination
of pipe and elbows to the appliance adapter with
seams oriented towards the wall or floor.
Twist-lock Procedure:
The female ends of the
pipes and fittings have three locking lugs (indenta-
tions). 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 sec-
tion clockwise approximately one-quarter turn until
the sections are fully locked.

fireplace in front of its permanent location to insure
minimum clearances. Mark the wall for an 11

able).
Figure 20.
The center of the hole should
align with the center line of the horizontal rigid vent
pipe end. Be sure to allow for minimum rise. Cut
