Page 4: Installation
Installation NOTE: If you have a Back Supply Fig. 1 Plenum, this must be installed before 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.
Page 5: Filler Panels
End Filler Panel Installation Instructions End filler panels may be shipped loose for field installaton or are facory mounted to the hood. If fillers are factory mounted to hood, skip this section. 1. Uncrate the hood and lay it on the floor with protective material between the hood and the floor. .
Page 6: Ductwork
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.
Page 7: External Supply Plenums Installation
External Supply Plenum Installation The purpose of the external supply plenum is to provide make-up air to an exhaust hood to maintain the air balance in the space. The external supply plenum must be hung independent of the hood. Follow the instructions for hanging the following supply plenums: Horizontal, Air Curtain and Variable. See page 8 for Back Supply Plenum.
Page 8: Back Supply Plenum Installation
STEP 1 (IF MODULE < 6 ft.) Installing the Back Supply Plenum Installing the Supply Duct Collar L (MODULE WIDTH) 1. Find the center of the Back Supply Plenum. . If the Back Supply Plenum is less than 9 ft. 10 in. (99.7 cm) long, cut opening at the suggested location, centering the opening over the center of the Back Supply Plenum.
Page 9: Hanging The Hood
Hanging the Hood with Back Supply Plenum Before hanging the hood according to the hood installation instructions, please check the following: 1. Make sure the back supply unit is properly secured, as described in steps 5 and 6, page 8. .
Page 10 Full Enclosure Panels Before installing the enclosure panels, make sure the hood is hung in position with all the ductwork attached and fire system connections completed. 1. Tack-weld or clamp end enclosure panels onto standing seam (clamps provided). . Attach the end enclosure panels to the wall (fasteners by others). 3.

Duct Collar Installation Exhaust Ducts 1. If the exhaust duct has been factory mounted, skip this section. . The exhaust duct must be located within the shaded region of Fig. 0. Note dimensions. Dimension Y assumes a 3 in. (76. mm) integral airspace on the hood back. When no 3 in. (76. mm) integral airspace is present, Y=0 in.
Page 15: Exhaust Air Balancing Baffle (Eabb)
Exhaust Air Balancing Baffles (EABB) This is a guide to assist in determining if multiple hoods on one fan can be balanced to have equal static pressure. For multiple hoods on one fan to achieve their designed exhaust flow, all of the hoods must have equal static pressure at their designed exhaust flow.
Page 16: Balancing The Kitchen Exhaust
Balancing the Kitchen Exhaust System A. To determine the proper dining room air balance: 1. Refer to engineering drawings to determine total exhaust CFM from dining areas. (Exhaust fans, heating and air conditioning units, restrooms, etc.) . Determine the total CFM of make-up air supplied to dining area. 3.
Page 17 Measure the velocity of each location. A digital .75 in. (70 mm) rotating vane anemometer or equivalent Rotating Vane Anemometer is suggested. The center of the anemometer should be held in. (50 mm) from the face of the filters as shown in Fig.
Page 18 B. Supply (If Applicable): Example for Perforated Face Supply 1. Hood set up If the make-up air unit has a temperature control, it should be used to keep the supply air at the desired room discharge air temperature. . Measure Velocities Divide the perforated face panel into a grid of equal areas, each approximately 4 in.
