Double Island Style Hoods

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

A double island hood is created by installing two wall style hoods back to back. Use the installation procedure
described on page 8, for single island hoods to 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 SCS-1009 or its equivalent). The caulk is not provided.

Installing U Channel Trim Strip

1. 

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

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 SCS-
1009 or its equivalent). The caulk is not 
provided.

Note: The installation of the canopy hoods shall be in accordance with NFPA 96 (latest edition), Removal of
Smoke and Grease-laden Vapors from Commercial Cooking Equipment.

See separate instructions for proper installation of enclosure panels, backsplash panels, and end skirts when
provided.  

Please see Pages 15 -19  for the installation instructions.

After the hood is installed, remove all protective plastic.

Note: GFC 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.
