Vent/Combustion Air
Terminal Kit - Required
on ALL SSCBL
Installations
All Model SSCBL installations require a vent/combustion air kit (Option CC2 or CC6)
including a concentric adapter box for each duct furnace. See page 19 (Option CC6)
or page 22 (Option CC2) for the component list of each kit. Be sure all of the factory-
supplied and field-supplied parts needed for the vent/combustion air kit(s) are at the
job site.
Other shipped-separate options could include a roof curb, an outside air hood, a gas
shutoff valve, a thermostat, an optional control switch, a remote console, a vent exten-
sion, a gas supply regulator, and/or a disconnect switch. If ordered with either an
evaporative cooling module or a DX or chilled water cooling coil module, the module
is shipped separately. A drain and fill or freeze kit and a water hammer arrestor are
shipped-separate options for an evaporative cooling module.
