York Comprehensive Guide for the DJ048 Air Conditioner

•ROOF CURBS - Eight and fourteen-inch high roof curbs provide a water-tight seal between the unit and the fin- ished roof. These full perimeter curbs meet the require- ments of the National Roofing Contractors Association (NRCA) and are shipped knocked-down for field assem- bly.

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 nano grams 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.

•CO2 SENSOR - Senses CO2 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 prevent unit from hail damage. This is a sloped hood that fits above the coil.

•GAS PIPING KIT - This kit supplies all necessary fittings and shut off valve.
