Install Ductwork; Prepare The Hood - Kenmore 233.5139 Serie Manual De Uso

1. Determine whether hood will discharge vertically (3¼" x 10"
or 7" Round) or horizontally (3¼" x 10" only).
2. Run ductwork between the hood location and a roof cap
or wall cap.
3. The ducting from this fan to the outside of the building has
a strong eff ect on the air fl ow, noise and energy use of
the fan. Use the shortest, straightest duct routing possible
for best performance, and avoid installing the fan with
smaller ducts than recommended. Insulation around the
ducts can reduce energy loss and inhibit mold growth.
Fans installed with existing ducts may not achieve their
rated airfl ow. Refer to the table below to help you plan
the most effi cient installation.
4. Install wall cap or roof cap (sold separately); ensure there
is no leak in hoiouse insulation. Connect metal ductwork
to cap and work back towards the hood location. Use 2"
metal foil duct tape to seal the joints between ductwork
sections.
