Combustion- -Air Vent Pipe, Fitting & Cement Material - Carrier 120 Series Operating Instructions Manual

NOTE: Do not allow insulation or other materials to accumulate
inside of pipe assembly when installing it through hole.
4. Locate assembly through sidewall with rain shield posi-
tioned no more than 1- -in. (25 mm) from wall as shown in
Fig. 47.
5. Disassemble loose pipe fittings. Clean and cement using
same procedures as used for system piping. DO NOT CE-
MENT POLYPROPYLENE FITTINGS.
2- - Pipe (Direct Vent) and 1- - Pipe (Ventilated Combus-
tion Air) Vent Termination
NOTE: Follow the instructions of the vent terminal manufacturer.
These instructions are provided as a reference, only.
NOTICE
RECOMMENDED SUPPORT FOR VENT
TERMINATIONS
It is recommended that sidewall vent terminations in excess of
24 inches (0.6 M) in vertical length be supported by EITHER
the Direct Vent Termination Kit shown in Table 12 or by
field- -supplied brackets or supports fastened to the structure.
Determine an appropriate location for termination kit using the
guidelines provided in section "Locating The Vent Termination" in
Table 13 – Approved Combustion-Air and Vent Pipe, Fitting and Cement Materials (U.S.A. Installations)

this instruction.
1. Cut two holes, one for each pipe, of appropriate size for
pipe size being used.
2. Loosely install elbow in bracket (if used) and place as-
sembly on combustion- -air pipe.
3. Install bracket as shown in Fig. 47 and 49.
NOTE: For applications using vent pipe option indicated by
dashed lines in Fig. 47 and 48, rotate vent elbow 90_ from
position.
4. Disassemble loose pipe fittings. Clean and cement using
same procedures as used for system piping. DO NOT CE-
MENT POLYPROPYLENE FITTINGS.
For ventilated Combustion Air Terminations, terminate as
shown in Fig. 48.
(Direct Vent / 2-Pipe System ONLY)
When two or more furnaces are vented near each other, two vent
terminations may be installed as shown in Fig. 47, but next vent
termination, or pair of vent terminations, must be at least 36 in.
(914 mm) away from the first two terminations. It is important that
vent terminations be made as shown in Fig. 47 to avoid
recirculation of vent gases.
Inducer Outlet Restrictor
The loose parts bag may contain an inducer outlet restrictor. The
outlet restrictor is NOT used on these furnaces. Discard restrictor.
