How to Install a Central Vacuum Exhaust

Central vacuum cleaners go a long way in making the chore of cleaning our homes a lot easier. Probably the biggest advantage to a central vacuum cleaner is that it doesn't exhaust the dirty air back into your home. Unfortunately some systems vent into the garage or basement where the dust and dirt can find its way right back into your home. If you want to take full advantage of your central vacuum cleaner's ability to clean your home and keep it dust-free, vent your system outside. This can be accomplished with a few easy steps.

Things You'll Need

• Central vacuum cleaner exhaust kit
• Drill bit
• Hammer drill
• PVC pipe sized to fit the exhaust kit for your central vacuum system
• PVC finishing ring
• PVC cement
• Exterior vent cover or flap similar to those used for clothes dryers
• Weatherproof caulk
• Hole saw

Instructions

Install a Central Vacuum Exhaust

1. Choose the location for placement of your central vacuum exhaust. This should be on a wall close to your unit to avoid a long run of PVC pipe. Make sure the exhaust is away from doors, windows, patios or other outdoor living spaces.

2. Trace a circle where you want the exhaust vent located, with the end of the PVC pipe.

3. Drill a pilot hole from the inside wall through to the outside. If your garage is made of cement block or brick, use a masonry bit. Cut out the circle using a hole saw for sheetrock or a hammer drill for block or brick construction.

4. Push the PVC pipe through the hole so there is approximately 1 to 2 inches protruding to the outside. You should have enough pipe protruding on the inside to allow you to easily connect a finishing ring.

5. Add the PVC finishing ring to the interior side of the pipe using PVC cement. This is where you will connect your central vacuum cleaner's exhaust kit following the manufacturer's instructions that come with your specific kit.

6. Attach the vent cover or flap to the exterior pipe.

7. Add a bead of weatherproof caulk around the PVC pipe where it enters through the wall. This will help keep out drafts, moisture and insects.
