4. Once the damper assembly is secured to the fan, turn it over so that the damper is at the

bottom. The fan can now be installed by two methods. The first is by utilizing vertical

hangar wires, minimum 12 SWG (2.7), attached to the damper sleeve (require one per side).

The second is to use the suspension bracket assembly provided by the fan manufacture.

5. The penetration in the ceiling should be located within the ceiling tiles or panels without

necessitating cuts in the ceiling suspension main runners or cross tees. If a cut is needed, a

maximum of one runner or cross tee may be cut to enable proper damper location and

installation. Each cut end shall be supported by a min 12 SWG (2.7) vertical hanger wire.

The opening in the ceiling should be the same size as the outside of the damper frame.

6. Position the damper and fan assembly such that the bottom edge of the damper is flush with

the finished surface of the ceiling. Attach the damper and fan assembly to the structure

above or adjacent to it. If the damper and fan are being attached to the assembly above, a

minimum of 12 SWG (2.7) hangar wire must be used. A minimum of four hanger wires are

required, one on each side. The hanger wires can be attached either to the damper sleeve or

the fan housing as specified in the fan installation instructions.
