Sidewall Mounting Installation
1. Cut an appropriate sized hole in the wall and follow
manufacturer's instructions on curb installation.
Mount the curb to the interior of the wall with
a minimum of eight 3/8-inch fasteners around
the flange. Caulk and flash the curb to ensure a
watertight seal.
2. If unit is equipped with a backdraft damper, it
should be installed now.
3. Lift the fan into place. Do NOT support the unit by
the hoodband during installation.
4. Orient fan so the grease trough is downward and
secure fan to curb using a minimum of eight lag
screws, metal screws or other suitable fasteners.
5. Follow steps 6 through 12 of General Ventilation
Installation instructions on page 4.

ELECTRICAL – If fan motor is NOT thermally protected, remote
overload protection must be installed having adequate rating as to
voltage, frequency, horsepower, and full load current per phase.
Where connected to a circuit protected by fuses, use time delay fuses.
For supply connection use wires rated for at least 90°C (194°F).
INSTALLATION – When connecting electrical power to this fan,
movement for possible future belt or wheel adjustment.
CAUTION – Any fan inlet or outlet that is non-ducted must be
protected by an appropriate guard.
ATTENTION – Tout ouverture d'admission ou de refoulement
du ventilateur non raccordée à une gaine doit comporter une
protection adaptée.

Typical Roof Mounting Installation
1. On the roof surface, cut an appropriate sized hole
and follow manufacturer's instructions on curb
installation. Caulk and flash the curb to ensure a
watertight seal.
2. If unit is equipped with a backdraft damper. DO NOT
install it.
Perform steps 3 - 12 of General Ventilation Installation.
IMPORTANT
The size of the duct must be equal to or larger than
the inlet opening of the fan.
To comply with NFPA 96, the fan discharge must be a
minimum of 40 in. (1016 mm) above the roof surface
and a minimum of 10 ft. (3048 mm) from any building
air intake.
Per NFPA 96, ductwork to an upblast discharge
exhaust fan must be constructed of and supported
by carbon steel not less than No. 6 MSG (1.52 mm) or
stainless steel not less than No. 18 MSG (1.21 mm) in
thickness. Duct must also extend a minimum of 18 in.
(457 mm) above the roof surface.
Ensure that a minimum of 500 ft/min of air velocity
through the duct is maintained per NFPA 96, clause
8.2.1.1, 2014 edition and UL 762, Issue #7, clause 6.2,
October 14, 2013.
The following accessories may be required by
NFPA 96 depending upon installation: Grease Trap,
Hinge Kit or Hinged Base, Clean-Out Port, and Vented
Curb.
Minimum duct velocities must be maintained in
kitchen exhaust applications. If a speed controller is
used, ensure compliance with all applicable codes.
