8 Johnson Controls Unitary Products

• ELECTRIC HEATERS wired for single point power sup-

ply. These nickel chromium heater elements are pro-

vided with limit and automatic reset capability to prevent

operation at excessive temperatures.

• ROOF CURBS - Eight and 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.

Roof curbs are 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.

• LOW NOX KIT- Required to reduce the emission of

nitrogen oxides below 40 nanograms per joule.

• POWER EXHAUST - Our single input economizer

options are available with power exhaust. Whenever the

outdoor air intake dampers are opened for free cooling,

the exhaust fan will be energized to prevent the condi-

tioned space from being over-pressurized during econo-

mizer operation.

The power exhaust option can only be used on bot-

tom duct configurations.

• 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.

• 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.

• CO

SENSOR - Senses CO

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.

• HAIL GUARD -Hail Guard Kit is available to protect coils

from damage. This is a sloped hood that fits above the

outdoor coil.

• GAS PIPING KIT - This kit supplies all necessary fittings

and shut off valve.

TABLE 1: SOUND POWER RATING

1. These values have been accessed using a model of sound propagation from a point source into the hemispheric\free field. The

dBA values provided are to be used for reference only. Calculation of dBA values cover matters of system design and the fan

manufacture has no way of knowing the details of each system. This constitutes and expectation to any specification or guaran-

tee requiring a dBA value or sound data in any other form than sound power level ratings.
