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.

25. Optional Vertical Louvers - Option CD1

The purpose of the addition of optional vertical louvers is to in- crease the air pattern spread. The vertical louver assembly is de- signed to be field assembled and installed. Refer to the instructions packaged with Option CD1 for a list of components and step-by- step installation instructions (Do not add optional vertical louvers to a fan-type heater with downturn nozzle Option CD3. See Paragraph 26.)

CAUTION: To avoid getting burned, adjust louvers prior to heater operation. If louvers need re-adjusting after start-up, wear protective gloves.

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. Suspen- sion point dimensions are found in Dimension Charts in Paragraph 3. On fan-type heaters, do not install Option CD5 or use vertical louvers with Option CD3.

27. 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.
