8. Duct Hole Framing: Cut or frame a hole through
the outside of the enclosure for the installation
of the duct inlet hood. A 5" (127 mm) diameter
hole is required. Feed the loose end of the flexible
duct through the hole cut for the inlet hood and
attach to the collar on the inlet hood using two
(2) short screws (provided), then wrap with duct
tape. Insert the hood into the opening. Secure in
place with nails driven through the holes in hood
flange. Seal with noncombustible waterproof
silicon type caulking. If additional duct is needed,
use Class 0 metallic air duct (refer to Figure 12).
NOTE: The Class 0 metallic air duct can be routed
out the back wall or side wall, up through the ceiling
or floor joists to an outside wall. Check local build-
ing codes for any restrictions. We recommend that
the inlet be at least four (4) feet above grade level.
