INSTALLATION INSTRUCTIONS

CAUTION: MAKE SURE POWER IS SWITCHED OFF AT SERVICE PANEL BEFORE STARTING INSTALLATION.

SECTION 1

Preparing the Exhaust Fan

1.Unpack fan from the carton and confirm that all pieces are present. In addition to the exhaust fan you should have:

1 - Grill with Light Lens1 - Damper Assembly (attached)

2 - #8 Screws

2 - Lockwashers

4 - Mounting Rails

1 - Instruction/Safety Sheet

2.Remove the fan’s venturi assembly, which is secured in place with one screw through the venturi (Figure 1). This is a captive screw and will stay installed in the venturi. Keep the venturi assembly and the grill in the carton until needed so they do not get damaged or lost.

Figure 1

3.Choose the location for your fan. To ensure the best air and sound performance, it is recommended that the length of ducting and the number of elbows be kept to a minimum, and that insulated hard ducting be used. Larger duct sizes will reduce noise and airflow restrictions. This fan will require at least 6" of clearance in the ceiling or wall, and will mount through drywall up to 3/4" thick. The

fan mounts between 16" or 24" on center joists using the 4 provided mounting rails.

4.Select the most convenient electrical knockout and remove using a straight-blade screw driver (Figure 2).

SECTION 3

Existing Construction

1.Set housing in position between the joist and trace an outline onto the ceiling material (Figure 4). Set housing aside and cut opening, being careful not to cut or damage any electrical or other hidden utilities. Install the side rails on the housing and position the housing in the previously cut hole so that it is flush with the finished ceiling. Secure the ends of the rails to the joists with screws or nails (not included) (Figure 3).

CAUTION: ALL DUCTING MUST COMPLY WITH LOCAL AND NATIONAL BUILDING CODES.

1.Connect the ducting to the fan’s duct collar (Figure 5). Secure in place using tape or screw clamp. Always duct the fan to the outside through a wall or roof cap.

New Construction

1.Install the side rails on the housing and position the housing next to the joist. Using the gauge on the fan’s housing, line up housing so that it will be flush with the finished ceiling. Secure the ends of the rails to the joists with screws or nails (not included). Slide the housing into its final position (Figure 3).
