INSTALLATION REQUIREMENTS
ELECTRICAL
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.
3. If hood contains UV option, provide 120 VAC 20Amp service to each
hood section for UV lights.
4. Hoods with UV option will require cabling and possible dampers controls.
See Gaylord provided electrical schematic.
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.
