Hood Installation Overview

Installation

NOTE: If you have a Back Supply

Plenum, this must be installed beforeFig. 1 the hood. Please see page 8 now.

Prior to installation, check with local authorities having jurisdiction on clearances to combustible surfaces.

With the hood still inside its packing crate, position the unit beneath its installation location.

Carefully remove the packing crate. Place some protective material on

the floor next to the crate to avoid

damaging the hood as it is tipped on its side (Fig. 1). Tip the hood carefully onto the protective material. If you have filler panels, see Fig. 2 below. If you have integral filler panels, no additional installation is needed.

If a Back Supply Plenum is provided, install first. Before raising hood, insert 1/2 in. (12.7 mm) diameter threaded rod (by others) into hanger brackets on hood top. Check the engineering drawings or UL label located on the inside of the hood for proper hood height above finished floor. Install filler panels if needed. Raise and hang hood from adequate roof or ceiling supports and secure mounting flange to the wall using lag bolts, or fasten to the Back Supply Plenum if provided. All hanger brackets must be used and the hood must be properly supported while lifting to prevent damage or distortion to the hood. The hood must be hung level to operate properly. After hood is secured, make the exhaust duct connections. The fire system distributer must be contacted at this time. After the fire system has been installed, mount the enclosures, then the supply plenums. If a Horizontal Supply Plenum is provided, it should be installed according to the external supply plenum installation section found on page 7. The hood and accessories are now installed. Finally, make the electrical connections from switches to fans and complete the fire system circuits as required by the job specification.

Rear Filler Panel Installation Instructions

Rear filler panels may be shipped loose for field installaton or are integral to the hood. If fillers are integral to hood, skip this section.

1.Uncrate the hood and lay it on the floor with protective material between the hood and the floor.

2.Bolt the filler panels together with 5/16 in. bolts from the hardware package.

3.Position the filler panels on the hood, and tack- weld them to the hood back.

4.To allow for ease of cleaning, caulk the external seams with NSF Approved silicone caulk

(GE SCS1009, or its equivalent). The caulk is not provided.
