Typical Installation

MODELS 744L • 744RL • 744RNL

The ducting from this fan to the outside of the building has a strong

effect on the air flow, 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 airflow.

Plan to supply the unit with proper line voltage and appropriate

power cable.

INSTALLATION

2. Mark mounting location.

Position unit between joists and extend mounting brackets.

IMPORTANT: Position brackets so there will be an 1/8” gap

between bottom of housing and ceiling material. Mark the

top of keyhole slot on all four mounting brackets.

The unit must not be installed above or inside the cooking area shown.

Do not install in a cooking area.

3. Pound in nails.

all four marked locations.

4. Hang and secure housing.

Hang unit from nails. Check to make sure that there will be a 1/8”

gap between bottom of housing and ceiling material. Pound nails

tight. For wide joist centers: A #8 x 3/8 self-tapping screw can be

used to join extended brackets together and create a rigid mount.

To ensure a noise-free mount, crimp the bracket channels tightly

around mounting brackets.
