Note: The installation of the canopy hoods shall be in accordance with NFPA 96 (latest edition), 
Standard for Ventilation Control & Fire Protection of Commercial Cooking Operations.

After the hood is installed, remove all protective plastic.

Note: Accurex does not recommend walking or standing on the hood top as damage can result. If you 
must walk on the hood top, protect the hood with additional support or planks for flooring.

Ductwork

Electrical Connections

Access for wiring the hood control panel (when applicable) is provided by a junction box located on 
top of the hood when the control panel is mounted in the hood, or by the switch junction box when the 
control panel is mounted in the fire protection cabinet. The box is labeled “Control Voltage Wiring to 
Roof Top Fan Package”. Use minimum 14 AWG copper wire. After all the wiring is completed, install 
the light bulbs (light bulbs not provided; standard light bulbs up to 100 watt may be used).

Caution: For multiple hood systems that have more than 14 lights total (incandescent or fluorescent), 
the hood lights must be wired to multiple circuits. Each circuit must have less than 14 lights total. 

Standard Accurex light switches shipped on hoods are rated for 15 amps and shall not have more than 
14 lights connected to them. Higher amperage switches are available upon special request.

Exhaust

As specified in NFPA 96, Ch. 7.5 (latest edition), exhaust duct systems must be constructed in the 
following manner:

Materials

. Ducts shall be constructed of and supported by carbon steel not less than 1.37 mm 

(0.054 in.) (No. 16 MSG) in thickness or stainless steel not less than 1.09 mm (0.043 in.) (No. 18 MSG) 
in thickness.

Installation:

 All seams, joints, penetrations, and duct to hood collar connections shall have a 

liquid-tight external weld. If you have an Automatic Fire Damper please refer to that manual for 
installation instructions now.

Supply

Supply ductwork (where applicable) should be connected to the hood in a manner approved by the 
local code authorities.

Note: For hoods with fire dampers in the exhaust and supply duct collars, an access panel for cleaning 
and inspection shall be provided in the duct. This panel shall be as close to the hood as possible but 
should not exceed 18 in. (45.72 cm).

For proper installation of duct collars when they are shipped unattached, see page 16.
