LISTINGS

FOLLOW SMACNA GUIDES AND RECOMMENDATIONS FOR THE HANGING AND

This hood is ETL-listed to standard UL710 when installed in accordance with these installation instructions and National Fire Protection Association Standard “NFPA 96, Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations.”

INSTALLATION

It is imperative that this unit is installed and operated with the designed airflow, filters and construction in accordance with this manual. If there are any questions about any items, please call the service department at 1-866-784-6900 for warranty and technical support issues.

WARNING: IMPROPER INSTALLATION, ADJUSTMENT, ALTERATION, SERVICE OR MAINTAINANCE CAN CAUSE PROPERTY DAMAGE, INJURY OR DEATH. READ THE INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS THOROUGHLY BEFORE INSTALLING OR SERVICING THIS EQUIPMENT.

Site Preparation

1. Provide clearance around installation site to safely rig and lift equipment into its final position. Consider general service and installation space when locating unit.

2. Locate unit close to the space it will serve to reduce long, twisted duct runs.

3. Thoroughly review the plans and specifications of the project.

4. Determine the exact location in which the cooking hood will be installed and verify that there are no interferences which will prevent proper installation.

5. Verify that all overhead beams and angles are structurally strong enough to support the weight of the hood and hanging system. It is often necessary to strengthen existing structural beams, as they are not designed to carry the weight of a stainless steel hood. Refer to the project submittal drawing for hood weight(s). It may also be necessary to create a support structure suspended from the ceiling joists to better align with the desired hood location.

6. Determine if adequate room is available to install the hood and all ductwork with proper clearances from combustible material. IMC, NFPA96 and local authorities having jurisdiction call for a minimum clearance (typically 18 inches for type 1, grease rated hoods) between the cooking hood(s), exhaust ducts, and building materials which are combustible. However, IMC and NFPA96 outline acceptable clearance reduction methods; most authorities accept the

clearance reduction methods approved in the manufacturer’s ETL listing for Type 1, grease rated hoods. See Figure 1. It is important to check with the local authority having

jurisdiction to determine that the installation method is satisfactory to meet their requirements prior to installing the equipment.

INSTALLATION OF HOODS.

Clearance Reduction Methods

Figure 1

Installation of a Single Hood

The following is a step-by-step procedure for installation of the ventilation hood.

1. Uncrate the hood, being very careful not to dent or scratch the outer surface. NOTE: Report any damage to the delivering freight carrier and file a claim if appropriate. Refer to the installation drawing for typical details of the ventilation system prior to hanging the hood. Check the nameplate on the equipment to make certain it meets the specifications provided by the architect and/or engineer. If discrepancies exist, notify the manufacturer immediately.

The nameplate will also give information regarding the following:

• Clearance from cooking surface to front lower edge of the hood

• Minimum exhaust air flow

• Maximum supply air flow (if applicable)

• Minimum front overhang from cooking surface

• Minimum side overhang from cooking surface

• Maximum cooking surface temperature

• Replacing fusible links for exhaust and supply damper (if applicable)

• Replacing filters

2. Determine the height at which the hood will be hung: Canopy hoods are typically hung so that the front lower edge of the hood is within 6'6" - 7'0"

AFF. However, the hood should be hung so that the proper clearance from the cooking surface to the front lower edge of the hood is maintained. See nameplate for clearance from cooking surface to front lower edge of hood. Exact hood hanging height should be verified with local authorities having jurisdiction.

Note: If there are wrappers (enclosure panels) with the order, measure down from the ceiling the height of the wrappers. That will be the top hanging height of the hood as long as the following criteria are met:

• The front lower edge of the hood is within 6’6” to 7’0” AFF,

• The front lower edge of the hood is within the clearance requirement from the

cooking surfaces, and

• The top of the hood is at least 3” away from the ceiling.

If the hanging height based on wrappers does not fall in this range, contact your local office. Backshelf hoods are typically hung at the maximum height allowed from the cooking surfaces.

See nameplate for clearance from cooking surface to front lower edge of hood. Exact hood hanging should be verified with local authorities having jurisdiction.

Note: If there are wrappers with the order, measure down from the ceiling the height of the wrappers. That will be the top hanging height of the hood as long as the front lower edge of the hood is within the clearance requirement from the cooking surfaces. If the hanging height based on wrappers does not fall in this range, contact your local office.

3. If the hood has a back return, install it now. See the Installation of Hood Accessories section.

4. If the hood has a bolt-together standoff, install it now. See the Installation of Hood Accessories section.

5. If the hood has duct thermostats, install them now per the thermostat installation drawing.

6. Position hood on the floor in its approximate final position with the supply and exhaust risers on the hood located directly beneath the corresponding openings in the roof, if possible. It is

advisable to finalize the location using a plumb-bob or laser. Protect the hood when it is on the jacks to avoid dents, scratches, and other damage to the hood.

7. Proceed to weld exhaust duct to hood while on the floor, if possible.

8. Use 1/2” threaded rod to hang hoods. Drill 9/16” holes in the structural support system or use Unistrut® to line up with the welded-on angle mounting brackets on the hood. There are several types of mounting brackets depending upon the hood type; each, however, has a predrilled hole. See Figure 2 for detail. The structural integrity of the structural support system is the responsibility of the contractor and the structural engineer. There are also center hanging angles on hoods 12 feet in length and longer. Some backshelf hoods do not have hanging angles and must be anchored to back wall using the standing flange provided. Structural lagbolts must be used every 12 inches on center maximum and must be secured to studs behind wall.

9. The spacing on the hole for the modified support should line up with the mounting bracket on top of the hood. The top hanger should be 1/2” closer to the back wall than the mounting bracket on the hood to pull the hood against the wall. See Figure 3.

10. With the hood well protected against possible scratching, raise the hood into position using high lifts or equipment jacks at each end to keep the hood level. When the hood is elevated to the proper height, install 1/2” threaded rod between each mounting bracket on the hood and the modified support. Secure rods with heavy duty nuts and appropriately sized fender washers above and below the hanging angle.

11. Make final adjustments as needed to ensure the hood is hung level. Maintain tension on all rods to ensure the hood weight is evenly distributed. If it is necessary to stand or work on top of the hood, use pieces of plywood to evenly distribute weight on the hood so no damage occurs.

12. Brace hood to ceiling joists and wall(s), as applicable, so that the hood does not move. Secure hood to wall in a manner acceptable to the authority having jurisdiction.

13. If the hood has Back and/or Side Perforated Supply Plenums (i.e. PSPs), install them now. See the Installation of Hood Accessories section.

14. If an AC-PSP is to be installed with the hood, install it now. See the Installation of Hood Accessories section.

15. Install the exhaust ductwork. The entire exhaust duct system must be continuously welded, liquid tight unless it is Listed Factory Built Grease Duct. The duct must be welded to the hood exhaust collar and the roof curb cap must be welded to the exhaust duct. See Guidelines for Ductwork Installation - By Others.

16. Install the supply ductwork. See Guidelines for Ductwork Installation – By Others.

17. If the hood is equipped with a control unit, an installation wiring diagram will be provided inside of the control unit. The jobsite electrician is responsible for making the appropriate field connections. This includes all lights and duct/hood mounted thermostats.

18. If the hood is equipped with a factory prepiped fire suppression system, a certified fire system installer is responsible for completing the field hookup, testing, and certifying the system in accordance with the manufacturer’s specifications and the local fire codes. If the hood is not prepiped, a certified fire system installer is responsible for installing, testing and certifying the system in accordance with the manufacturer’s specifications and the local fire codes.

19. If the hood is equipped with wrappers (enclosure panels), end panels, and/or backsplash panels, install them now. See the Installation of Hood Accessories section.

20. Caulk the lower edge of the hood where it meets the wall.

21. Install light bulbs, light globes, and grease filters in the hood.

22. Install grease cups in the brackets/slots provided.

23. Use a stainless steel polish to clean the hood of dust or dirt acquired in transit.

24. It is recommended that the protective plastic sheeting remain on the installed hood until construction is complete, so as to avoid any damage to the equipment.

WARNING: NEVER PUNCTURE THE HOOD GREASE CONTAINMENT AREA TO HANG HOOD OR TO HANG ITEMS FROM HOOD. PUNCTURING THE GREASE CONTAINMENT AREA WILL VOID WARRANTY AND LISTING ON HOOD.

End-to-End Hoods

The following is a step-by-step procedure for installation of end-to-end ventilation hoods. Refer to Figures 4 and 5.

1. Follow steps 1 through 10 of the Installation of a Single Hood section for each hood.

2. Adjust tension on hanging rods to position hoods so they fit flush with each other as shown in Figure 4.

3. Bolt the top of the hoods together. See Figure 5.

4. Once all of the hoods are hung, follow steps 11 through 19 of the Installation of a Single Hood section.

5. NOTE: Hoods having more than a 1/8” gap between them must be repositioned so that gap between hoods is <= 1/8”. Run a bead >=1/8” of silicone sealant along the lower horizontal seam of the two hoods. Slip the U-channel trim, if applicable, over the seam as shown in Figure 4. Tape can be used to hold the U-channel in place until the silicone cures. U-channel is not required on hoods with Flanged ends.

6. Run a bead of the same silicone sealant along the front vertical seam between the two hoods. Slip the T-strip trim between the hoods if applicable. See Figure 5. T Strip is not required on hoods with flanged ends and fully welded, ground, and polished corners.

7. Proceed with steps 20 through 23 of the Installation of a Single Hood section.
