FIELD-INSTALLED ACCESSORIES
SINGLE INPUT ELECTRONIC ENTHALPY ECONO-
MIZERS
 - Includes a slide-in / plug-in damper assembly 
with fully modulating spring-return motor actuator capa-
ble of introducing up to 100% outdoor air with nominal 
1% leakage type dampers.
The enthalpy system contains one sensor that monitors 
the outdoor air and determines when the air is cool 
enough and dry enough to provide free cooling.
The rainhood is painted to match the basic unit and must 
be field-assembled before installing.
MOTORIZED OUTDOOR AIR INTAKE DAMPER - 
Includes a slide-in / plug-in damper assembly with a 2-
position, spring return motor actuator which opens to 
some pre-set position whenever the supply air blower is 
operating and will drive fully closed when the blower unit 
shuts down.
The rain hood is painted to match the basic unit and 
must be field assembled before installing.
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.
HIGH ALTITUDE NATURAL GAS - Burner orifices and 
pilot orifices are provided for proper furnace operation at 
altitudes up to 6,000 feet.
PROPANE - Burner orifices, pilot orifices and gas valve 
parts are provided to convert a natural gas furnace to 
propane.
HIGH ALTITUDE PROPANE - Burner orifices and pilot 
orifices are provided for proper furnace operation at alti-
tudes up to 6,000 feet. This accessory supplements the 
basic propane conversion kit.
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.
HIGH STATIC DRIVE - A smaller blower pulley and a 
shorter belt increase the speed of the supply air blower 
for applications with a higher CFM and/or static pressure 
requirements.
ENTHALPY ACCESSORY CONTROL KIT - This kit 
contains the required components to convert a single 
enthalpy economizer to dual enthalpy.
BURGLAR BARS - Mount in the supply and return 
openings to prevent entry into the duct work.
FLUE EXHAUST EXTENSION KIT - In locations with 
wind or weather conditions which may interfere with 
proper exhausting of furnace combustion products, this 
kit can be installed to prevent the flue exhaust from 
entering nearby fresh air intakes.
WOOD SKID - Allows unit to be handled with 90” forks.
CO
2
 SENSOR - Senses CO
2
 levels and automatically 
overrides the economizer when levels rise above the 
present limits.
COIL GUARD - Customers can purchase a coil guard kit 
to protect the condenser coil from damage. This is not a 
hail guard kit.
PHASE MONITORS - Designed to prevent unit damage. 
The phase monitor will shut the unit down in an out-of-
phase condition.
