WARNING

TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR

1. Use this unit only in the manner intended by the manufacturer.
If you have questions, contact the manufacturer at the address
or telephone number listed in the warranty.

2. Before servicing or cleaning unit, switch power off at service

disconnecting means cannot be locked, securely fasten a
prominent warning device, such as a tag, to the service panel.

3. Installation work and electrical wiring must be done by a
qualified person(s) in accordance with all applicable codes
and standards, including fire-rated construction codes and
standards.

4. Sufficient air is needed for proper combustion and exhausting
of gases through the flue (chimney) of fuel burning equipment
to prevent backdrafting. Follow the heating equipment
manufacturer’s guideline and safety standards such as those
published by the National Fire Protection Association (NFPA),
and the American Society for Heating, Refrigeration and
Air Conditioning Engineers (ASHRAE), and the local code
authorities.

5. When cutting or drilling into wall or ceiling, do not damage
electrical wiring and other hidden utilities.

Typical Installation

• Installation is the same for:

Joists I-Joists Trusses

• Fits in 2" x 8" ceiling construction.

• Infinitely adjust the fan position
between joists from 14" to 24"
on center.

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, straighest 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.

6-inch round rigid metal duct is recommended for best performance.
