The rain hood is painted to match the basic unit and
must be field assembled before installing.
Power exhaust is not available as a field installed option.
•
ROOF CURBS - Fourteen-inch high roof curbs provide a
water-tight seal between the unit and the finished roof.
These full perimeter curbs meet the requirements of the
National Roofing Contractors Association (NRCA) and
are shipped knocked-down for field assembly.
They're designed to fit inside the base rails of the unit
and include both a wood nailing strip and duct hanger
supports.

SIDE DUCT FLANGES - One-inch flanges replace the
supply and return air panels on the rear of the unit to
accommodate horizontal duct connections. These
flanges can also be used individually for bottom supply/
horizontal return or horizontal supply/bottom return. They
cannot be used on units with power exhaust.
•
BAROMETRIC RELIEF DAMPER - This damper acces-
sory can be used to relieve internal building air pressure
on units with an economizer without power exhaust. This
accessory includes a rain hood, a bird screen and a fully
assembled damper. With bottom duct connections, the
damper should be mounted over the opening in the
return air panel. With horizontal ductwork, the accessory
should be mounted on the return air duct.

shorter belt increase the speed of the supply air blower
for applications with a higher CFM and/or static pressure
requirements.
