If the Back Supply Plenum is less than 9 ft. 10 in. (299.72 cm) long, cut opening at the suggested location, centering the opening over the center of the Back Supply Plenum. (Fig. 9) L/2 L/2 3. If the Back Supply Plenum is greater than 9 ft. 10 in. (299.72 cm) long, divide the length of the back supply by four.
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. 2. Any filler panels should be attached to the hood before the hood installation. To hang the hood: 1. Lift the hood and position it so the top of the hood is even with the back supply (Fig. 13). This height should correspond to the UL hanging height of the hood. 2.
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). 2. Attach the end enclosure panels to the wall (fasteners by others). 3. Position the front enclosure panel(s) on the hood and bolt to the end enclosure panels with the 5/16 in. bolts provided. 4.
Plate Shelf with Duct Enclosure Panels Before installing the enclosure panels, make sure the hood is hung in position with all the ductwork attached and the fire system connections completed. Plate shelf will be factory mounted to hood (shown loose). 1. Tack-weld or clamp end enclosure panels into place (clamps provided). 2. Attach the end enclosure panels to the wall (fasteners are not provided). 3. Position the front enclosure panel(s) on the hood and bolt to the end enclosure panels with the 5/16 in.

Duct Collar Installation Exhaust Ducts 1. If the exhaust duct has been factory mounted, skip this section. 2. The exhaust duct must be located within the shaded region of Fig. 20. Note dimensions. Dimension Y assumes a 3 in. (76.2 mm) integral airspace on the hood back. When no 3 in. (76.2 mm) integral airspace is present, Y=0 in. (0 mm). 3. Cut out appropriate size hole to match the duct collar provided. 4. The exhaust duct connection is to be a continuous liquid-tight weld.
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. The laws of physics force the static pressure for each branch of a duct system on one fan to always be equal.
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.) 2. Determine the total CFM of make-up air supplied to dining area. 3. Subtract #1 from #2 above. If the result is a negative number, a negative pressure is present in the dining area. In this case, kitchen exhaust odors could be drawn from the kitchen to the dining area.
Measure the velocity of each location. A digital 2.75 in. (70 mm) rotating vane anemometer or equivalent is suggested. The center of the anemometer should be held 2 in. (50 mm) from the face of the filters as shown in Fig. 22. It is helpful to make a bracket to keep the anemometer at the 2 in. (50 mm) distance and parallel to the filter. Both squareness and distance are very important for accuracy. Airflow Rotating Vane Anemometer 2 in. Fig. 22 Calculate the average velocity for the filter. 3.
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. 2. Measure Velocities Divide the perforated face panel into a grid of equal areas, each approximately 4 in. (100 mm) square. Measure the velocity at the center of each grid area. A digital 2.75 in. (70 mm) rotating vane anemometer or equivalent is suggested.

XX Filters, first row of filters 1A 1B XG Filters, second row of filters 1C Step 2 Release the hooks that hold the filters together. Slide the top hook upward and the bottom hook downward until the hook releases. Do this to all filters.
Filter Washing Frequency Guide Note: Standard cooking will turn the beads yellow in color. Open flame cooking will cause the beads to blacken. Neither affects the performance of the beads. Caution: To prevent damage to filter media, do not wash second stage filters in detergents that contain hydroxides such as sodium hydroxide or potassium hydroxide.
Troubleshooting Problem: Exhaust fan is not operating or is not operating at design levels. Is the fan receiving power? Replace fuses, reset circuit breakers, check disconnect. Is the belt loose or broken? Replace or tighten belt. Is the fan rotating in correct direction? Have the electrician correctly wire the fan. Is the make-up air operating? Problems with make-up air may interfere with the exhaust fan check the manufacturers installation manual.
Troubleshooting Problem: Smoke blows away before reaching the bottom of the hood. Are there pass-thru windows near the hood? Adjust amount and locations of make-up air to eliminate drafts through the pass-thru windows. Is this an air curtain hood? Turn off or reduce the amount of make-up air. Is the make-up air part of the hood or an attached plenum? Try turning off or reducing the amount of make-up air; block off portions of the supply to direct air away from the problem area (test with cardboard).
