NOTE: If you have a Back Supply Plenum (BSP), this must be installed before the hood. Please see Page 10.

Fig. 1

For Wall/Single Island Style Hoods, prior to installation, check with local authorities having jurisdiction on clearances to combustible surfaces, etc.

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, install them now; Fig. 2. If you have integral filler panels, no additional installation is needed.

Hood Installation Overview

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 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 distributor must be contacted at this time. After the fire system has been installed, mount the enclosures, then the supply plenums. If an Horizontal Supply Plenum is provided, it should be installed before the enclosures. 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.

Filler Panel Installation Instructions

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

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

3. Position the filler panels to the hood back, and tack-weld them into place. (Fig. 2)

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.

ITEM-1A

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. The grease trough is pitched to drain into the grease container.

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 5 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 SCS1009 or its equivalent). The caulk is not provided.

Continuous Capture Plenum Hoods

Remove the support angles on the open end panels. (see Fig. 3) Use the installation procedure described on page 4 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, (see Fig. 4). Caulk this joint with NSF Approved silicone caulk (GE SCS1009 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. (Fig. 5)

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 SCS1009 or its equivalent). The caulk is not provided.

Canopy Hood

Note: The installation of the canopy hoods shall be in accordance with NFPA 96 (latest edition), Standard for Ventilation Control & Fire Protection of Commercial Cooking Operations.

After the hood is installed, remove all protective plastic.

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.

Electrical Connections

Access for wiring the hood control panel (when applicable) is provided by a junction box located on top of the hood when the control panel is mounted in the hood, or by the switch junction box when the control panel is mounted in the fire protection cabinet. The box is labeled “Control Voltage Wiring to Roof Top Fan Package”. Use minimum 14 AWG copper wire. After all the wiring is completed, install the light bulbs (light bulbs not provided; standard light bulbs up to 100 watt may be used).

Caution: For multiple hood systems that have more than 14 lights total (incandescent or fluorescent), the hood lights must be wired to multiple circuits. Each circuit must have less than 14 lights total.

Standard Greenheck light switches shipped on hoods are rated for 15 amps and shall not have more than 14 lights connected to them. Higher amperage switches are available upon special request.

Ductwork

Exhaust

As specified in NFPA 96, Ch. 7.5 (latest edition), exhaust duct systems must be constructed in the following manner:

Materials. Ducts shall be constructed of and supported by carbon steel not less than 1.37 mm (0.054 in.) (No. 16 MSG) in thickness or stainless steel not less than 1.09 mm (0.043 in.) (No. 18 MSG) in thickness.

Installation: All seams, joints, penetrations, and duct to hood collar connections shall have a liquid-tight external weld. If you have an Automatic Fire Damper please refer to that manual for installation instructions now.

Supply

Supply ductwork (where applicable) should be connected to the hood in a manner approved by the local code authorities.

Note: For hoods with fire dampers in the exhaust and supply duct collars, an access panel for cleaning and inspection shall be provided in the duct. This panel shall be as close to the hood as possible but should not exceed 18 in. (45.72 cm).

For proper installation of duct collars when they are shipped unattached, see page 16.
