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 m). See
Figure 14.
Only one 45° elbow is allowed in these installations.
VENTING INSTALLATION
1. Rigid vent pipes and fittings have special
twist-lock connections. Assemble the desired
combination of pipe and elbows to the
appliance adaptor.
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 adja-
cent pipes and fittings. Push the pipe sections
together and twist one section clockwise
approximately one-quarter turn until the sec-
tions are fully locked. See Figure 15.
2. Locate and cut the vent opening in the wall.
For combustible walls first frame in opening.
Combustible Interior Walls: Cut a 11
