NOTES:
1) See vent system manufacturer’s literature for other part numbers that are required such as straight
pipe, elbows, firestops and vent supports.
2) Part No. 101004-01 collar replaces factory-mounted concentric collar (Figure 7.16).
6) Permitted Terminals for Vertical Venting
-
•
Vent Option 5
- A straight termination is installed in the end of the vent pipe. Vent manufacturer part numbers for these
screens are shown in Table 7.5. The air inlet terminal consists of a 180 degree elbow (or two 90 degree elbows) with a
rodent screen as shown in Figure 7.10
•
Vent Option 6
- Use U.S. Boiler part 101495-01 with the appropriate flashing (see Table 7.4b).
7) Vertical Vent Terminal Locations (Vent Options 5, 6) - Observe the following limitations on the location of all vertical vent
terminals (see Figures 7.10 and 7.11):
• The top of the vent pipe must be at least 2 feet above any object located within 10 feet.
• For Vent Option #5, the vertical distance between top of the vent and air inlet terminal openings must be at least 12".
• The bottom of the air inlet terminal must be at least 12” above the normal snow accumulation that can be expected on
the roof. The terminal used in Vent Option #6 has a fixed distance above the storm collar of 19". If a greater distance
is needed to provide the clearance above the snow line, build a chase on the roof and mount the vertical terminal on top
of the chase.
• For Vent Option #5, the air intake terminal must be located on the roof and must be no further than 24" horizontally
from the exhaust pipe.
8) Wall thimbles – Wall thimbles are required where single wall vent pipe passes through combustible walls with less than
the required clearance shown in Table 4.2 or as required by local codes. Stainless vent manufacturer’s wall thimble part
numbers are shown in Table 7.5. Note that concentric vent has a "zero" clearance to combustibles and therefore does not
require the use of wall thimbles.
