ii. Combustion Air Termination
• After penetrating wall, install a 90°
elbow so that the elbow leg is in the up
direction.
• Install maximum vertical run of seven (7)
feet of combustion air pipe. See Figure
11.
• At top of vent pipe length install another
90° elbow os that the elbow leg is
opposite the building’s exterior surface.
• Install Rodent Screen (not supplied) and
horizontal vent terminal.
• Brace exterior piping if required.

Vertical Vent Termination
a. Standard Two-Pipe Termination
Refer to Figures 12 and 13.
i. Vent Termination
• Use the terminal supplied by the vent
system manufacturer shown in Table
11B. Follow manufacturer’s instructions
to attach terminal to vent system.
ii. Combustion Air Termination
• Install vertical combustion air terminal.
Vertical combustion air terminal consists
of an 180° bend (comprised of two (2)
90° elbows) as shown in Figure 12.
• Install rodent screen (not supplied) in the
combustion air terminal. Use a screen
having 1/2” (2 x 2) or larger mesh.
E.
Concentric Polypropylene Venting
1. Vent Length Restrictions
a. Vent length restrictions are based on equivalent
length of vent pipe i.e. total length of straight
pipe plus equivalent length of fittings. See
Table 12 for specified vent length details. Do
not exceed maximum vent length. Table 13
lists available concentric vent components and
includes equivalent vent length for fittings.
b. The vent termination location is restricted as per
‘General Guidelines’, Paragraph A, 5 (refer to
Figure 4).
