INSTALLATION

1. Hood to be installed in accordance with NFPA-96 Standard for Ventilation

Control and Fire Protection of Commercial Cooking Operations and all

other local applicable codes. Contractors must review applicable codes

with code authorities before approving drawings for fabrication. Special

attention must be given to code regulations relative to clearances from

surrounding combustible constructions (walls, ceilings, etc.).

2. If the hood is manufactured in multiple sections and include light fixtures,

the electrical contractor is responsible for inter-wiring the lights between

hood sections.

3. Exhaust duct must be continuously welded to the hood duct collar. All

ductwork beyond the hood duct take-off collar must be installed, in

accordance with applicable codes. Exhaust ducts must be grease and

water tight with continuous external welds.

4. All hoods are equipped with continuous hanging flanges. Hanging rods

to be supplied by hood installer. Hanging weight of the hood(s) is noted

on the submittal drawing.

5. Hoods are manufactured in strict accordance with Gaylord specifications

and the Gaylord UL Procedure Manual.

6. Hoods are constructed of 18 Ga. stainless steel, Type 304, No. 4 finish

unless otherwise noted on drawings.

AIR FLOW RATES

1. The exhaust air flow rates (and supply if part of the hood) must be set

at the rate stamped on the hood nameplate. The exhaust volumes (and

supply when provided) were established under controlled laboratory

conditions and greater exhaust and/or lesser supply may be required for

complete vapor and smoke removal in specific situations.

FIRE EXTINGUISHING SYSTEM

1. Fire extinguishing system furnished and installed by contractor must

be in accordance with the terms of it's listing and the applicable NFPA

codes.

2. Caution: Fire extinguishing system piping installed on the hood at job

site should be coordinated with the Gaylord Manufacturer to ensure

piping does not interfere with hood's operation/performance. Improper

installation may void UL Listings of the hood.

3. IMPORTANT NOTE: NFPA-96 requires that all gas cooking equipment

and electric cooking equipment, that is protected by surface fire

protection, must automatically shut off upon activation of the fire

extinguishing system.

4. IMPORTANT NOTE: Most building departments require separate hood

and fire protection permits prior to installation.The hood permit is typically

obtained through the plan review department and the fire protection

permit from the fire prevention bureau. It is the responsibility of the

installing contractor to check with local building departments for their

requirements and to obtain necessary permits.
