DO NOT mount the blower unit by the cover, or by

When mounting the main blower housing, be sure
to fully engage the inlet collar of the blower with the
round duct inlet from the downdraft ventilation unit.
Secure the outlet to the exhaust duct.
Make sure that there is an appropriate damper
installed on the discharge ducting, per local code or
national building code, to prevent backfl ow of air.

3¼"x14" / 4"x14" / 4¾"x14" size, or a combination of
both. PVC duct should be used if installing under a
poured concrete slab. Use the shortest and straightest
duct run possible.
