WARNING
In areas of high snowfall, users
must be advised to check
side wall vent and air intake
terminations on a regular basis
to ensure blockage does not
occur.
CAUTION
Take care installing Concentric

when the outdoor temperature
drops below 5°F/-15°C. Possible
blockage of the combustion
air intake can occur when the
outdoor temperature drops below
this temperature.

d) Sidewall Direct Vent with Stainless Sidewall Terminal shall be terminated as
follows:
• The Stainless Sidewall Terminal (SST), 2 inch IBC part number 180-148 (sold
separately included with the IBC kit P-256 ) or 3 inch IBC part number 180-149 (sold
separately included with the IBC kit P-257 ), are approved for use with the this IBC
boiler model.
• The boiler's controller is required to be the touchscreen type and have software
version 1.02.0 or later installed for SST to be used.
• Install the SST to comply with the minimum vent clearances listed in a) above.
• The installation instructions included with the kit shall be carefully followed.
• The SST shall only be installed with the vent and intake pipes horizontally beside
each other or vertically with the vent pipe on top as shown in Figure 15. The vent pipe
cannot be installed below the intake. The vent cap must be installed with the openings
directed up and down, as shown in Figure 15, and not side to side.
• The SST vent/air connections fit Sched. 40 two inch or three inch PVC/CPVC pipe.
PPs pipe cannot be used with the SST. The pipes must extend completely through the
wall as shown in Figure 16. The SST is an external fixture, and is not part of the sealed
vent system that runs inside the building.
• Ensure that the vent termination location does not exceed the allowed maximum
equivalent vent length, including the allowance for the SST, defined in this document
section 1.4.3 Vent Travel and section 1.4.7 "Direct Vent" Combustion Air Intake Piping.
• Install multiple vent SST installations level with one another and maintain at least the
minimum separation distances shown in Figures 14 and 15. The Terminals shall not be
stacked vertically.
