Greenheck Fan GGH20 Hood Hanging Height, Double Island Style Hoods, Installing U-Channel Strip

Hood Hanging Height

The hood hanging height is critical. Hanging the hood at the incorrect height may significantly reduce the ability for the hood to function properly and may be in violation of codes. The hood hanging height (typically, 78 in. (198.12 cm) above the finished floor) is given on the UL label located on the inside of the hood on the end panel. The hood must be hung level to operate properly.

NOTE

Before hanging the hoods, please verify the hood marks to make sure the correct hood is hung on the correct side.

Double Island Style Hoods

A double island hood is created by installing two wall style hoods back to back. Use the installation procedure for single island hoods; install and level both hoods. After leveling, secure the hoods together by tack-welding and/or bolting the rear mounting brackets. Caulk this joint with NSF Approved silicone caulk (GE SCS1000 or its equivalent). The caulk is not provided.

Installing U-Channel Strip

1.After the hood is hung in position and leveled, apply caulk to the inside edge of the double island clip.

2.Position and install the clip by tapping into position along clip (friction fit).

3.Caulk edges to seal out grease and allow for ease of cleaning. Caulk with NSF Approved silicone caulk, GE SCS1000, or its equivalent. The caulk is not provided.

NOTE

Greenheck does not recommend walking or standing on the hood top as damage can result. If you must walk on the hood top, protect the hood with additional support or planks for flooring.

Continuous Capture Plenum Hoods

Remove the support angles on the open end panels. Use the installation procedure described for single island hoods; install and level both hoods. After leveling, secure the hoods together by tack-welding and/or bolting the top angles. Fasten the hoods together using u-clips and bolts. Caulk this joint with NSF Approved silicone caulk (GE SCS1000 or its equivalent). The caulk is not provided.
