Things You'll Need:
- Central vacuum exhaust kit
- Drill
- Pencil
- Hole saw(for drywall and siding) or Hammer drill with masonry bits(for concrete walls)
- PVC cement
- Pipe cutter or hack saw
-
Step 1
Select a location for your outside central vacuum exhaust. This should be away from A/C compressors, outdoor living areas, walkways, entryways, etc.
-
Step 2
Begin by drilling a pilot hole from the inside to your outside exhaust location.
-
Step 3
On the inside, use a stop coupling and trace a circle around the pilot hole.
-
Step 4
Using a hole saw for drywall and siding, or a hammer drill for masonry, cut out the circle you have traced. For masonry, use the hammer drill to drill a hole every half inch or so, on the inside of the circle you traced. When you have finished you should be able to tap it out with a hammer. Repeat this on the outside and be sure to line up the holes. Now, stub a pipe through the hole. On the outside the pipe should protrude 1 or 2". The inside pipe should protrude enough to line up with your power unit.

Step 5
Before you complete the inside tubing, you can decide which finish treatment to use on the exterior exhaust. One choice is to use a 45 degree coupling. First place a trim ring around the vac tube and then attach the 45 degree coupling pointed downward. (You may want to use a little bead of caulk behind the trim ring.)
-
Step 6
Another choice for the outside exhaust is an exhaust flap. The exhaust flap is screwed to the outside wall.
-
Step 7
Next you go inside and place a trim ring on the exhaust pipe coming through the wall. Now you can attach your power unit to the exhaust pipe. If your vacuum is on the same wall as your exhaust pipe begin at your power unit using the couplings, sweeps, and pipe in your exhaust kit to join the power unit to the outside exhaust pipe. The muffler should be placed somewhere between the unit and the outside exhaust.
-
Step 8
If your power unit is on a wall other than the wall where your exhaust is located, run pipe up, over, and down to your outside exhaust pipe. Most manufacturers recommend that your exhaust line not exceed 15 feet.
-
Step 9
Note: All joints need to be glued using PVC cement.
