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.
Sidewall direct vent with stainless sidewall terminal must be terminated as follows:
The Stainless Sidewall Terminal (SST) 2 inch (IBCkit P-256) and 3 inch (IBC kit P-257)
are approved for use with this appliance.
Install the SST to comply with the minimum vent clearances listed in Table 5 .
Install the SST with the vent and intake pipes horizontally beside each other or vertically
with the vent pipe on top (see Figure 25 ). The vent pipe cannot be installed below the
intake. The vent cap must be installed with the openings directed up and down (see
Figure 25 ), and not side to side.
Figure 25 Allowed SST installation orientations
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 below. The SST is an external fixture, and is not part of the sealed vent
system that runs inside the building.
