INSTALLATION (continued)
Site Preparation
1. Provide clearance around installation site to safety rig and lift
equipment into its nal position. Consider general service and
installation space when locating unit.
2. Thoroughly review the plans and specication of the project.
3. Determine the exact location in which the cooking hood will be
installed and verify that there are no interferences, which will
prevent proper installation.
4. 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.
5. Determine if adequate room is available to install the hood with
proper clearance from combustible material. IMC, NFPA96 and
local authorities having jurisdiction call for a minimum clearance
(typically 18 inches) between the cooking hood(s) and building
materials, which are combustible. However, IMC and NFPA96
outline acceptable clearance reduction methods. 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 (continued)
MECHANICAL INSTALLATION
The following is a step-by-step procedure for installation of the Recirculating Hoods.
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 le 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 specications provided by the architect and or
engineer. If discrepancies exist, notify the manufacturer immediately.
2. It’s important that you have read and understand “Site Preparation” before continuing with the installation
of the hood. See Table on page 6 “EQUIPMENT PARAMERTUER”.
3. Determine the exact location of the hood. Ensure support beams are structural support system is
the responsibility of the contractor and the structural engineer.
4. Use 1/2-13 threaded rod to hang the hood. Drill 5/8” holes in the structural support system using
dimensions provided below.
5. Each corner of the hood has a pre-punched hole. It is important that the 1/2-13 threaded rod that
will be used to suspend the hood is secured at these locations. Each hole has a 14 gauge steel
support plate that is riveted to the inside of the lid to strengthen the hood corners. Do not remove or
relocate these plates.
6. Raise the hood into position using high lifts or equipment jacks at each end of the hood to ensure the
hood is level. When the hood is elevated to the proper height, install 1/2-13 threaded rod between
the hood support plates and the modied supports in the ceiling.
7. Make nal adjustments as needed to ensure that the hood is level. Maintain tension on all the rods
to ensure hood weight is evenly distributed.
