This hood is factory set for venting through the roof (vertical
discharge) or wall (horizontal discharge). A 3 1 ⁄4" x 10" (8.3 x
25.4 cm) rectangular duct system is needed for installation (not
included). The hood exhaust opening is 3 1 ⁄4" x 10" (8.3 x 25.4
cm).
NOTE: Flexible vent is not recommended. Flexible vent
creates back pressure and air turbulence that greatly reduce
performance. Vent system can terminate either through the roof
or wall. To vent through a wall, a 90° elbow is needed.
Vertical Discharge
Use a rectangular duct 3 1 ⁄
" x 10" (8.3 x 25.4 cm) and a 3 1 ⁄4" x

Preparation
Do not cut a joist or stud unless absolutely necessary. If a joist or
stud must be cut, then a supporting frame must be constructed.
Fittings material is provided to secure the hood to most types of
walls/ceilings.
However, a qualified technician must verify suitability of the
materials in accordance with the type of wall/ceiling.
Before making cutouts, make sure there is proper clearance
within the ceiling or wall for exhaust vent.
