FACTORY OPTIONS AND/OR ACCESSORIES (cont.)
Flue Discharge Deflector
The flue discharge deflector is a useful accessory when
flue gas recirculation is a concern. By venting the flue
discharge upwards, the deflector minimizes the chance for
a neighboring unit to intake the flue exhaust (04- - 14 sizes
only).
Optional Stainless Steel Heat Exchanger
The stainless steel heat exchanger option provides the
tubular heat exchanger be made out of a minimum 20
gauge type 409 stainless steel for applications where the
mixed air to the heat exchanger is expected to drop below
45_F (7_C). Stainless steel may be specified on
applications where the presence of airborne contaminants
require its use (applications such as paper mills) or in
areas with very high outdoor humidity that may result in
severe condensation in the heat exchanger during cooling
operation.
Flue Discharge Heat Shield
The flue discharge heat shield keeps people from touching
the rooftop unit's potentially hot flue discharge. This is
especially useful for ground level applications, where
more, untrained people could have access to the unit's
exterior (04- - 14 sizes only).
Alternate Motors and Drives
Some applications need larger horsepower motors, some
need more airflow, and some need both. Regardless of the
case, your Carrier expert has a factory installed
combination to meet your application. A wide selection of
motors and pulleys (drives) are available, factory
installed, to handle nearly any application.
Thru- - the- - Base Connections
Thru- - the- - base connections, available as either an
accessory or as a factory option, are necessary to ensure
proper connection and seal when routing wire and piping
through the rooftop's basepan and curb. These couplings
eliminate roof penetration and should be considered for
gas lines, main power lines, as well as control power.
Supply Duct Cover
This supply duct cover is required when field converting
the factory standard vertical duct supply to horizontal duct
supply configuration. One required per unit (16 size only).
California OSHPD Seismic Certification
Label
Units meet the seismic requirements of the International
Code Council Evaluation Service (ICC- - ES) document
AC156 (Acceptance Criteria for Seismic Qualification by
Shake- - Table Testing of Nonstructural Components and
Systems) and per International Building Code (IBC 2009)
at an SDS (g) value of 2.00 z/h=1.0, Ip=1.5 and certified
by independent structural engineers. A certification label
is applied to the unit that meets the CA OSHPD Special
Seismic Certification pre- - approval labeling requirements
on the external chassis of the unit.
