INSTALLATION
SL 28-160 MODULATING GAS BOILER
•
Bird screen of 1/4" stainless steel or plastic mesh eg. (IPEX System 636 drain
grate for CPVC systems) is useful to guard against foreign objects.
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 IBC kit P-256 ) or 3 inch IBC part number 180-149
(sold separately included with IBC kit P-257 ), are the only direct vent sidewall
terminals approved for use with the this IBC boiler model.
•
The boiler's controller is required to be the Touch Screen type and have
software version 1.02.0 or later installed for SST to be used.
•
The SST shall be installed in compliance 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
12. 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 12, 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 13. The SST is an external
fixture and 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.
•
Multiple vent SST installations must be installed level with one another and
maintain at least the minimum separation distances shown in Figure 14 and
15. The Terminals shall not be stacked vertically.
