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.
L/2
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
FIG. 14
FIG. 10
to that manual for installation instructions now.
For hoods with fire dampers in the exhaust and
supply duct collars, an access panel for cleaning and
L/4
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).
Supply
- Supply ductwork (where applicable) should
be connected to the hood in a manner approved by the
local code authorities.
FIG. 14
For proper installation of duct collars when they are
shipped unattached, see page 8.
