28. Optional Duct Flange - Option CD9 (Blower Models only)
Blower-type unit heaters may be connected to ductwork. The duct flange option is designed to adapt the heater outlet (supply side) for connection
to ductwork.
Ductwork connection sizes are shown in the chart below.
Follow the installation instructions included with the option package.
OPTIONAL EQUIPMENT
This section contains a brief description of the more frequently specified field-installed options. All option packages include complete assembly and
installation instructions.
26. Optional Vertical Louvers -
Option CD1
The purpose of the addition of optional vertical louvers is to increase
the air pattern spread. The vertical louver assembly is designed to be
field assembled and installed. Refer to the instructions packaged
with Option CD1 for a list of components and step-by-step instal-
lation instructions (Do not add optional vertical louvers to a fan-
type heater with downturn nozzle Option CD3. See Paragraph 27.)
CAUTION: To avoid getting burned, adjust
louvers prior to heater operation. If louvers need
re-adjusting after start-up, wear protective
gloves.
27. Optional Downturn Air Nozzles
- Options CD2, CD3, CD4, and
CD5
Unit heaters may be specified with optional downturn air nozzles to
direct the discharge tempered air. The nozzles are shipped separately for
field assembly and installation. The horizontal louvers are removed from
the heater and re-installed into the outlet of the downturn nozzle.
The addition of a downturn nozzle requires four-point heater suspension.
Two hanger brackets are included with downturn nozzle options and must
be added to fan-type heaters with standard two-point suspension. Sus-
pension point dimensions are found in Dimension Charts in Paragraph 4.
On fan-type heaters, do not install Option CD5 or use vertical louvers
with Option CD3.

29. Optional Polytube Adapter - Options CD6, CD8, and CD11 (Blower
Models only)
The polytube adapter option is designed to adapt this blower-type heater for use with polytube ductwork. The use of polytubes for air distribution
is common in greenhouse applications and some industrial applications. A polytube distribution system delivers warm air to a specific area, reducing
the need for complete area heating. The polytube adapter is available in three installation designs making it adaptable to many applications and
building structures.
WARNINGS: This adapter is to be used only on units equipped with a blower. At no time should the free
area in the polytube be less than the listed minimum. Failure to comply with these warnings could result in
severe personal injury, death and/or property damage.
