Ductwork

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 liquidtight continuous external weld.

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 14

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.

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