Exhaust Vent Installation
Project 3: Exhaust Vent Installation
Materials & Tools:
Materials & Tools:
- Exhaust Fan (150 – 300 CFM’s)
- Duct Work & Fittings
- Exterior Termination Cap
- Drill W/ 3˝ – 4˝ Hole Saw & Long ¼˝ Bit
- High Quality (Venting) Duct Tape
- Hammer, Pliers & Tape Measure
Step by Step:
Getting Started...
- Find the best location for the exhaust fan. Try to locate the fan so that the duct run is as short and straight as possible. Every elbow you add to the duct work diminishes the exhaust flow of the fan.
- Consult or hire a licensed electrician to run all the necessary wiring and install the wall switch. Make sure the location you choose to install the fan is free of any obstructions and is big enough to support the fan and duct work.
Installing the Exhaust Fan...
- Insert the fan housing in place, between two ceiling joists. Temporarily secure it and then measure the duct run to where it exits the house. Mark this exit location.
- Remove the fan housing and drill the exit hole for the duct work. Using the long ¼˝ wood bit drill a pilot hole all the way through the wall to where the duct work will exit the house. Now re-drill the pilot hole using the 3˝ or 4˝ hole saw, depending on the size of the duct work.
- Re-install the fan housing and permanently secure it in place. Connect the duct work to the housing exit port and run it over to and through the hole you drilled. There should be at least 2˝ of duct outside, extending past the exterior siding.
- Insert and secure the fan motor into the fan housing. Make all the necessary electrical connections. Note: Refer to the product instruction manual for more details on this step.
- Connect the exterior termination cap to the duct work on the outside and then secure it to the house.
- Test the fan to make sure its working properly. Finish the drywall around the exhaust fan and paint. The last step is to install the exhaust fan grill cover.
