Exhaust Ducts

1. If the exhaust duct has been factory mounted, skip this section.

. The exhaust duct must be located within the shaded region of Fig. 0. Note dimensions.

Dimension Y assumes a 3 in. (76. mm) integral airspace on the hood back. When no 3 in.
(76. mm) integral airspace is present, Y=0 in. (0 mm).

3. Cut out appropriate size hole to match the duct collar provided.

4. The exhaust duct connection is to be a continuous liquid-tight weld.

Supply Ducts

Proximity hoods do not have integral supply plenums. Reference External Supply Plenums (Page 7).

The final fire system hook-up must be completed at this time. Unobstructed access is required for the
fire system installer to make plumbing connections to various locations on the hood top. Do not install
any enclosures until the fire system installation is complete.
