Figure 17 Sidewall vent termination configuration option 2
Sidewall direct vent with stainless sidewall terminal must be terminated as follows:
The Stainless Sidewall Terminal (SST) three-inch (IBC kit P-257) is approved for use
with these appliances when the equivalent length calculation (for exhaust) in the
preceding table is used.
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. The vent pipe cannot be installed below the intake. The vent
cap must be installed with the openings directed up and down (see Figure 18), and not
side to side.
