• Install Rodent Screen (not supplied) and
horizontal vent terminal.
• Brace exterior piping if required.
5. Vertical Vent Termination
a. Standard Two-Pipe Termination
Refer to Figures 11 and 12.
i. Vent Termination
• Use the terminal supplied by the vent
system manufacturer shown in Table 8B.
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 11.
• Install rodent screen (not supplied) in the
combustion air terminal. Use a screen
having 1/2" (2 x 2) or larger mesh.

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 ttings. See
Table 9 for specied vent length details. Do
not exceed maximum vent length. Table 10
lists available concentric vent components and
includes equivalent vent length for ttings.
b. The vent termination location is restricted as per
'General Guidelines', Paragraph A, 5 (refer to
Figure 3).
