7. After pipes have been cut and preassembled, apply
generous layer of PVC primer to pipe fitting socket
and end of pipe to insertion mark. Quickly apply
PVC cement (over primer) to end of pipe and fitting
socket. Apply cement in light, uniform coat on inside
of socket to prevent buildup of excess cement. Apply
second coat of cement to end of pipe.
8 While the PVC cement is still wet, insert pipe into
socket with a I/4-turn twist. Be sure pipe is fully
inserted into fitting socket
9. Wipe excess cement from joint. A continuous bead
of cement is visible around perimeter of a properly
made Joint.
10. Handle pipe joints carefully until cement sets.
11. Support piping every 5 ft (minimum) using per­
forated metal hanging strap. Slope combustion-air
and vent pipes toward furnace a minimum of 1 /4-in./
lineal ft with no sags between hangers.
12 Use appropriate methods to seal openings where vent
and combustion-air pipes pass through roof or
sidewall
Vent Terminal Kit Installation — The combustion-
air and vent pipes must terminate outside the structure.
The Carrier accessory vent termination kit for 2-in.
diameter pipe (required) must be installed as shown in
Fig. 3, 4 or 5. Roof termination, shown in Fig. 3, is pre­
ferred. The kit contains extra parts for the various
applications.
NOTE: The shaded portions of Fig. 3, 4 and 5 are con­
sidered part of the vent terminal and are provided in the
vent terminal kit. They should not be counted, therefore,
in pipe diameter calculations.
