NOTE: See vent system manufacturer’s literature for other part numbers that are required such as straight pipe, elbows, restops
and vent supports.
Table 8B: Alternate Vent Systems and Vent Components (Stainless Steel)
• Male end of terminal will t into the
female end of any of the approved
stainless vent systems.
• Apply a heavy bead of silicone to the
male
end of the terminal before inserting
it into the last piece of pipe. Orient the
terminal so that the seam in the terminal
is at 12:00.
• Smooth the silicone over the seam
between the terminal and the last piece
of pipe, applying additional silicone if
necessary to ensure a tight seal.
• Allow the silicone to cure per the
silicone manufacturer’s instructions
before operating the boiler.
ii. Combustion Air
Termination
• Horizontal intake terminal is a tee in the
upright position. Tee should protrude
the same distance from the wall as the
exhaust terminal. See Figure 8.
• Install a rodent screen (not supplied) in
the inlet terminal. Use a screen having
1/2”
(2 x 2) or larger mesh.
b. Optional Two-Pipe Snorkel Termination
Refer to Figure 10.
This installation will allow a maximum of
seven (7) feet vertical exterior run of the vent/
combustion air piping to be installed on the
approved AL29C Stainless Steel horizontal
venting application.
i. Vent Termination
• After penetrating wall, install the
appropriate manufacturer's 90° elbow so
that the elbow leg is in the up direction.
• Install maximum vertical run of seven
(7) feet of appropriate manufacturer's
vent pipe. See Figure 10.
• At top of vent pipe length install another
appropriate manufacturer's 90° elbow
so that the elbow leg is opposite the
building's exterior surface.
• Install horizontal vent terminal.
• Brace exterior piping if required.
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 10.
• At top of vent pipe length install another
90° elbow os that the elbow leg is
opposite the building's exterior surface.
