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 16 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 pages 20-21 for further details.
• •
Belt Guard - Provides protection for building occupants as well as service people from the
drive belt and sheaves.
• •

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 18.1
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 1/2 to 50 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.
• • • • • •
Building Managment System - The Modine Building Management System (BMS) Board
installed in this unit provides an RS485 interface between the unit heater and existing
building networks that employ a BACnet or Modbus protocol.
