Newer models of bath fans are easy-to-install in that they don’t require extensive wiring, ductwork or cutting
Simplify the installation process when installing a new bath fan with a new, easy install model. "No cut" or roomside bathroom fan models can be installed in new construction or used to replace older fans in existing construction. Simply remove the old fan, attach the new housing, hook up the ductwork and wiring, and you’re done.
Not cut bathroom fans will fit into the standard existing hole in your ceiling or wall.
Roomside Install bathroom fans come equipped with an installation mechanism that allows the installer to install the fan without climbing up into the attic and attaching it to the joists. The installation for both types follows the same basic steps included in this guide.
What You Need
INSTALLING AN EASY INSTALL FAN IN NEW CONSTRUCTION
- Switch the power off at the fuse box.
- Remove the wiring panel or knockout from the fan housing with a flathead screwdriver.
- If necessary, assemble the fan according to manufacturer instructions. This may include attaching the damper and duct connector to the fan housing.
- Mount the housing to the ceiling. The bottom of the housing should be flush with the ceiling and perpendicular to the joist or stud. Tip: If mounting housing to an eye joist, use wood blocking.
- Connect the duct. Secure the duct to the duct connector using duct tape or clamps.
- Connect the house and fan wiring. Pull the existing wire through the hole and into the housing. Connect the power cable and wiring according to the wiring diagram provided in manufacturer’s instructions. Reattach the wiring box cover.
- If necessary, slide the blower into the housing and secure.
- Finish the ceiling work – the hole should align with the edge of the fan housing.
- Slide the grille into place and secure.
Turn the power back on once installation is complete.
INSTALLING AN EASY INSTALL FAN IN EXISTING CONSTRUCTION
- Switch off the power at the fuse box.
- Remove the existing fan, leaving the old duct work and wiring.
- Measure the ceiling opening and determine if it is large enough to accommodate your new fan. If not, you must cut around the current opening in order to increase the size of the opening. Be careful not to cut through any ducting or wiring when doing this.
Follow steps 3-10 of the new construction installation to complete.
