Installation

****IMPORTANT****

Installation of the vent pipe is CRITICAL to the operation of your BioLet Composting Toilet.

If you must vary the installation from these instructions in ANY WAY, please contact technical support at 1-800-524-6538 PRIOR to installation.

Straight run through ceiling and roof

  1. Position the toilet against the wall.alt installation 202
  2. Using a plumb-bob or a weighted string, find and mark the spot on the ceiling directly above the center of the ventilation outlet on top of the toilet.
  3. Drill a 2 1/4" hole in the ceiling where you just made a mark in Step 2.
  4. Drill a 2 1/4" hole in the roof above the hole in the ceiling.
  5. Insert 1 length of 54mm, white, belled pipe into the rubber connector on the back of the toilet with the belled end up. (Pipe will only go " to " into the rubber connector.)
  6. Insert the next white, belled pipe into the pipe installed in the back of the toilet. Repeat until the end of the white pipe extends through the roof.
  7. Cut the last pipe so only the bell of the pipe is sticking above the roof.
  8. Seal the hole in roof using the silicone to caulk around the pipe.
  9. Remove the 54mm white pipe and insulation from inside the 108mm black pipe. Keeping the reducing coupling attached to the white 54mm pipe with no bell.
  10. Slide non-belled black pipe into belled end of other black pipe.
  11. With the bell facing downward cut the black pipe so it fits the angle of the roof and the end other end extends at least 6" above anything within 10 feet if it. Wherever possible, extend the vent pipe above the peak of the roof. (The total length of the black piping must be at least 2'; 4' on roofs with less than a 3/12 pitch.)
  12. Cut the insulation to the angle of the roof as done with the black pipe in step 11.Roof Flasing (w330h251)02
  13. Slide the roof flashing over black pipe with the top of the flashing away from the cut end of the pipe.
  14. Reinsert white pipe and insulation into the black pipe with the reducing coupling toward the uncut end.
  15. Place the black pipe over the white pipe that extends from the roof, ensuring that the white pipe inside the black pipe securely joins with the pipe extending from the roof.
  16. Slide roof flashing down so it lies evenly on the roof, slipping its flanges under the shingles along the top edge.
  17. Outline the flashing on the roof.
  18. Raise the flashing and apply silicone sealant inside the outline.
  19. Slide the flashing back down, sliding the flange under the shingles along the top edge and press it firmly into the sealant. When the flashing is properly placed the top part of the flashing should be under the shingles and the lower portion should be on top so water sheds easily.
  20. Secure the top of the flashing with corrosion resistant nails or staples at each corner and along the sides at 4" - 6" intervals.
  21. Exposed nails or staples should be sealed with silicone sealant.
  22. Slide the reducing coupling down till it fits over the black pipe.
  23. Cut off the white 55mm pipe even with the top of the reducing coupling.
  24. Slide the insect netting down over the top of the reducing coupling. Secure it in place using a hose clamp.
  25. Plug the unit into a grounded 110 VAC outlet.

*** IMPORTANT ***

Wherever the ventilation pipe passes through an unconditioned area (i.e. attic space) it needs to be insulated. Use a pipe wrap with an insulating value of at least R11.

A rain cap is not necessary. If one is desired, use ONLY the BioLet authorized wind directional cap (Part# wind) that can be obtained from BioLet or your authorized dealer. Any other cap may hinder the airflow from the toilet and cause a reduction in the performance of the unit.

Through the exterior wall using 2 - 45 elbows.

54mm 45 elbows (part# 820021) and 108mm outside pipe kits (part# 506) may be purchased from BioLet or your authorized dealer.

  1. Position the toilet against the wall.
  2. Mark the place on wall directly above the vent opening on the toilet where you want the pipe to pass through the wall (*** MUST BE AT LEAST 8" ABOVE THE TOILET ***).
  3. Drill a 2 1/4" hole at a 45 angle through the wall where marked in the previous step.
  4. Cut the belled end off 1 length of 54mm white pipe.
  5. Insert the male stub of the 45 elbow into one end of the pipe you just cut in step 4.
  6. Pass the other end of the pipe/elbow assembly trough the hole you drilled in step 3.
  7. Measure the distance from the top of the vent pipe opening on the toilet to the end of the 45 elbow and add 2".
  8. Cut the belled end of the straight white pipe to achieve the length found in step 7. (you should now have a straight white pipe, non-belled)
  9. Insert 1 length of 54mm, white, belled pipe into the rubber connector on the back of the toilet with the belled end up. (Pipe will only go " to " into the rubber connector.)
  10. Insert the next white, belled pipe into the pipe installed in the back of the toilet. Repeat until the end of the white pipe reaches the 45 elbow. (the last pipe in this assembly should be the pipe you cut in step 8)
  11. Insert the male stub of the 45 elbow passing through the wall into the end of the pipe explained in step 10.
  12. Outside the structure cut the pipe sticking through the wall so only 2" of pipe are protruding.
  13. Insert the male stub of the 2nd 45 elbow into the pipe protruding through the wall.
  14. Insert the other male stub of the 45 elbow into the non-belled end of a 54mm white pipe.
  15. Wrap the pipe in step 14 in insulation and tape the seams using duct tape.
  16. Slide the non-belled 108mm black pipe over the insulated pipe in step 15.
  17. Continue the pipe upward as in the "Straight run through ceiling and roof" procedures above insulating each pipe as in steps 15 & 16 in this procedure. The remaining 108mm black pipes should be assembled with the belled end down.
