Figure 12: Sidewall vent termination - multiple vent piping configuration
For side venting of multiple unit sets, group all intake terminals together with 6"
(minimum) lateral spacing, and similarly group the exhaust pipes. Place the 2
groups on the same plane of the building (e.g., north facing wall). Place the 2
groups of pipes at least 3' apart (the closest intake and exhaust pipes must be
36" - or more – apart). Use same 12" (minimum) vertical separation (see A in
Figure 12). Alternatively, as long as the units are identical models - intake and
exhaust terminals can maintain a minimum of 12" of separation horizontally from
any exhaust or inlet termination of an adjacent unit (see B in Figure 12). For
alternative group terminations, contact the IBC Factory for written guidance.
Concentric Side Wall Termination Kits
Installation of multiple Concentric Side Wall Termination kits:
•
On the same horizontal line (not stacked)
•
With a minimum vertical separation of 12" center to center
Use caution when installing Concentric Side Wall Termination kits when the outdoor
design temperature is below 5°F / -15°C. Possible blockage of the combustion air
intake increases when the outdoor temperature drops below this temperature.
Approved Concentric Side Wall Termination Kits are listed below: (Alternative
vent termination kits must be submitted to IBC for approval prior to installation.)
