Installation Requirements

Code Compliance
Ventilators must be installed to comply with all applicable codes.
1. Ventilator to be installed in accordance with NFPA-96, Standard for Ventilation Control and Fire
Protection of Commercial Cooking Operations, the IMC, International Mechanical Code, and all other
local applicable codes.
2. All plumbing and electrical must comply with the applicable codes.
3. Contractors must review applicable codes with code authorities before approving drawings for
fabrication.
4. Special attention must be given to code regulations relative to clearances from surrounding
combustible constructions (walls, ceilings, etc.).
Permits
IMPORTANT NOTE: Most building departments require the Ventilator (hood) permit separate from any
other general building permit. In addition if a Fire Extinguishing System is involved a separate permit
from the Ventilator permit is typically required. The Ventilator permit is typically obtained through the
plan review department and the Fire Extinguishing System permit through the fire prevention bureau.
The installing contractor must check with local building departments for their requirements, and to
obtain necessary permits.
Ventilator Listing
The Gaylord Model CG3-UVi-SPC Series Ventilators are listed to UL 710 and Recognized by ETL. Any
modification made to the Ventilator at the jobsite will void the listing.
Hanging the Ventilator
Use the following guidelines for hanging the Gaylord Ventilator:
1. The maximum section length of a Gaylord Ventilator is 16'-0". Ventilators longer than 16"-0" are
made up of multiple sections.
2. The weight of the Ventilator is shown on the Gaylord Submittal Drawings.
3. Each Ventilator section has a full length Rear Mounting Bracket at the rear for bolting to the wall
and/or hanging from the overhead. There are two other full length hanging brackets; the Middle
Mounting Bracket and the Front Mounting Bracket for hanging from the overhead (Refer to Figure B-
2-1). All three Hanging Brackets have pre-punched holes for hanging from the overhead. Hanging
rods to be supplied by the Ventilator installer. If the rear bracket is used for bolting to the wall the
holes must be drilled by the installing contractor at a support point in the wall. .
4. It is recommended that the number of hanging rods used be no less than the recommend minimum
as shown on Table T-B-2-1.
5. The Ventilator(s) must be installed at the distance from the finish floor and the minimum side
overhang dimension from the end of the Ventilator to the cooking equipment as shown on the
Gaylord Submittal Drawings.
6. When there is a continuous Ventilator made up of two or more sections it is recommended that each
Ventilator section is hung individually. Angles are provided at the top of the sections for bolting
together. The bolts are provided by Gaylord. Hem strips and bolts are provided by Gaylord for
joining the Ventilators on the underside where visible.
