12. Mount the wall plate on the wall of the shaft (Fig. 9). Pay attention to
the correct slope of 3
o
. The pipe of the support elbow must be in the
center of the hole in the wallplate. See Fig. 9 for proper installation.
13. Depending on the type of system (single wall or concentric) the
support elbow can be shortened. For single wall, the length of A (Fig. 9)
must have a minimum length of 3” (40 mm). For concentric 60/100 end
80/125, the minimum length of A must be .8” (20 mm). For concentric
100/150, A must be 1.2” (30 mm).
14. Fix the correct version of the shaft connector to the wall plate (see
Fig. 9, 1 or 2).
15.
When installing the Polypro to PVC
adapter, first connect the adapter by
pushing it onto the Polypro pipe.
Be
certain that the arrow on the adapter
is
facing up.
Next, slide the PVC/CPVC
pipe
into the adapter. Use a flathead
screwdriver to tighten the adapter to the
pipe.
Once the adapter is connected, be
certain that it pitches ¼” per foot to
ensure proper condensate drainage (see
Figure 10).
Orientation of the Polypro to PVC adapter is critical. Be certain that the arrow on the adapter faces up. Failure
to ensure correct orientation of the adapter will lead to seal failure and an exhaust gas leak, resulting in
property damage, severe personal injury, or death.
