Sidewall Terminations
Concentric Vent
NOTE: Follow the instructions of the vent terminal
manufacturer. These instructions are provided as a reference,
only.
Determine an appropriate location for termination kit using the
guidelines provided in section “Locating The Vent Termination”
in this instruction.
1. Cut one 4−in. diameter hole for 2−in. kit, or one 5−in.
diameter hole for 3−in. kit.
2. Loosely assemble concentric vent/combustion air
termination components together using instructions in kit.
3. Slide assembled kit with rain shield REMOVED through
hole.
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
positioned no more than 1−in. (25 mm) from wall as
shown in Figure 47.
5. Disassemble loose pipe fittings. Clean and cement using
same procedures as used for system piping. DO NOT
CEMENT POLYPROPYLENE FITTINGS.
Direct Vent (2-Pipe) 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 side−wall vent terminations in excess
of 24 inches (0.6 M) in vertical length be supported by
EITHER the Direct Vent Termination Kit 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 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
assembly on combustion−air pipe.
3. Install bracket as shown in Figure 44 and Figure 46.
NOTE: For applications using vent pipe option indicated by
dashed lines in Figure 47 and Figure 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
CEMENT POLYPROPYLENE FITTINGS.
For Ventilated Combustion Air Terminations, terminate as
shown in Figure 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 Figure 44 and
Figure 46, but next vent termination, or pair of vent
terminations, must be at least 36−in. (914 mm) away from first
two terminations. It is important that vent terminations be made
as shown in Figure 44 and Figure 46 to avoid recirculation of
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.
