PREPARATION (Continued)
Inspect duct work and wiring before proceeding with installation.
Before installation, provide inspection and future maintenance access at a location that will not interfere with installation work.
Installation may vary depending on how the previous bath fan was installed. Supplies necessary for the installation of your bath fan are not all
included; however, most are available at your local home improvement or hardware store.

TYPICAL INSTALLATION
It is recommended to apply proper insulation around the fan to
minimize heat loss and gain. This fan is designed to be installed
using a 4-in. duct.
Using a rigid duct is recommended. Using a flexible duct, cut to
size and/or fully extended is also acceptable. Ducting 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.
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 air flow.

• Strip wires 3/8 in. - 1/2 in.
• Grip the wire firmly and push the stripped end of the
wire into the open port of the connector. Use only one
conductor per port.
• Verify the stripped end of the wires is fully inserted to
the back of the connector.
