Step 1 Roof Opening

For down discharge units, the chart below shows the maximum recommended roof opening dimensions. These sizes can be smaller based on codes and ductwork sizes. See page 10 for curb dimensions.

Step 2 Install Roof Curb

Center the curb over the roof opening as shown in first installation diagram at left.

Level the curb and shim if necessary. Attach curb to roof and flash in place.

Step 3 Install Ductwork

If this unit is a horizontal discharge, skip to Step 4. The chart (left) shows the duct sizes and straight lengths recommended for optimal performance (AMCA Publication 201-90). Using duct sizes and lengths less the recommended will affect fan performance. Good duct practices should be followed for the remaining ductwork. The use of a duct adapter with the supply duct is strongly recommended to properly align the ductwork with the supply fan discharge. The duct adapter is only a guide and is not intended to be used as support for the ductwork.

Sealant

Step 4 Apply Sealant

Before installing fan, apply a sealant around the perimeter of the supply duct adapter to isolate the fan and minimize vibration.

Step 5 Install Supply Unit

Use a crane hooked to the factory lifting lugs (as shown in the diagram) to lift and center the unit on the curb. For larger units with 7½ to 10 horsepower motors, it is recommended to use a spreader bar to support the unit while lifting.

Use self-tapping sheet metal screws to fasten unit to the curb through the holes provided.

Electrical connections can be made at this time.

Complete Installation

Illustration shows the complete installation of a downblast unit. If the unit is horizontal discharge, proceed to Step 6.

Step 6 Attach Ductwork to Unit Discharge

For horizontal discharge units: The chart and drawing show opening size and location for the 2 inch discharge collar. Also included is the recommended straight duct lengths for optimal performance. Greenheck recommends attaching ductwork to collar using a rubber duct section at the unit to eliminate vibration.

Step 4 Install Ductwork

Exhaust:

Exhaust ductwork must be built in accordance with NFPA 96 and any local codes. Ductwork terminating at the fan should be square in shape or of smooth transition so as not to to affect the fans performance.

Supply:

The chart at left shows the duct sizes and straight lengths recommended for optimal performance (AMCA Publication 201-90). Using duct sizes less than the recommended lengths will affect fan performance. Good duct practices should be followed for the remaining ductwork.
