1. If hoods are equipped with light fixtures, provide a separate 120 volt or 220 volt
lighting circuit to light J-box on the hood. Hood may be equipped with built-in
light switch.
2. If hood is provided with a built-in fan switch provide a separate 120 volt or 220
volt circuit to the fan switch J-box mounted on top of the hood. Fan switch is rated
for 20 amps, 277 volts, 1 h.p. at 120 volts, 2 h.p. at 220 volts, 16 amps max.
INSTALLATION
2. Hood to be installed in accordance with NFPA-96 Standard for Ventilation Control
and Fire Protection of Commercial Cooking Operations and all other local ap
-
plicable 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 construc
-
tions (walls, ceilings, etc.).
3. If the hood is manufactured in multiple sections and include light fixtures, the
electrical contractor is responsible for inter-wiring the lights between hood sec
-
tions.
4. 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 ap
-
plicable codes. Exhaust ducts must be grease and water tight with continuous
external welds.
5. 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 sub
-
mittal drawing.
6. Hoods are manufactured in strict accordance with Gaylord specifications and
the Gaylord UL Procedure Manual.
7. Hoods are constructed of 18 Ga. stainless steel, Type 304, No. 4 finish unless
otherwise noted on drawings.
AIR FLOW RATES
8. 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
9. Fire extinguishing system furnished and installed by contractor must be in ac
-
cordance with the terms of it’s listing and the applicable NFPA codes.
10.
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.
11.
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.
12.
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.
