ACCESSORiES
Table 13.1 - Field installed Accessories
Vertical Deflector Blades - Allows directional discharge air control in the left and right
directions.
Downward Air Deflector Hoods - Available in 30°, 60°, and 90° configurations these
deflector hoods enable the unit to be mounted higher while still providing heat to the building
occupants. Refer to page 14 for further details.
Vibration Isolation Kit - Minimizes unit vibration transmission to the building structure.
Pipe Hanger Adapter Kits - Allows the unit to be suspended by 3/4" pipe from the standard
3/8" holes found in the top of the unit.
Discharge Transition for Polytube - Allows for the connection of polytube (not included) to
the discharge of the unit.
Blower Enclosure with or without Filter Rack - Totally encases the motor and blower
assembly. Optional filters provide filtering of the air prior to entering the heater.
Discharge Velocity Generating Nozzle - Four varieties of velocity generating nozzles
allow for increased application flexibility. These nozzles increase mounting height while also
directing the airflow to the desired locations. Refer to page 15 for further details.
Belt Guard - Provides protection for building occupants as well as service people from the
drive belt and sheaves.
Natural Gas to Propane Gas Conversion Kit - Provides all required parts as well as
instructions to convert a natural gas unit to propane gas.
Single or Two-Stage Room Thermostats - See Table 13.2 for details.
Room Thermostat Guard - Clear plastic for room thermostats. Guard is locking type and
comes with two keys.
Summer/Winter Switch - Allows a choice of unit fan operation. In the summer position, the
fan runs continuously for ventilation while allowing the gas controls to fire on a call for heat
from the thermostat. In the winter position, the fan runs intermittently on a call for heat from
the thermostat.
Stepdown Transformers - Used to operate propeller units on 208/230/460/575V/3Ph
supply voltage. Also may be required for control circuits for blower units. Refer to Table
12.1 for further selection details.
Control Relays - This single pole single throw relay consists of a 24V coil with a maximum
contact rating of 18 amps at 115V.
Gas Pressure Regulator - Fisher Type S-100-, 3/4 inch pressure regulator for 5 to 10 psi
inlet pressure capacity, 30 MBH to 400 MBH.
Energy Saver Kit - Used to lower total energy costs by reducing stratified air in high
mounting height applications. This kit consists of a controller with a SPDT (16A @ 120V)
switch and a temperature rage of 30° - 100°F.
