Straight Run Through Ceiling And Roof - Biolet 20 Deluxe Owner's Manual

•
Verify that the total run for the vent pipe is less than 30' in a straight up installation or 27' if 2 – 45° angles are
required. Consult with BioLet USA technical support if a longer run is required.
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

Position the toilet against the wall.
1.
Using a plumb-bob or a weighted string, find and mark the
2.
spot on the ceiling directly above the center of the
ventilation outlet on top of the toilet.
Drill a 2 1/4" hole in the ceiling where you just made a mark
3.
in Step 2.
Drill a 2 1/4" hole in the roof above the hole in the ceiling.
4.
Insert 1 length of 54mm, white, belled pipe into the rubber
5.
connector on the back of the toilet with the belled end up.
(Pipe will only go ¼" to ½" into the rubber connector.)
Insert the next white, belled pipe into the pipe installed in
6.
the back of the toilet. Repeat until the end of the white pipe
extends through the roof.
Cut the last pipe so only the bell of the pipe is sticking
7.
above the roof.
Seal the hole in roof using the silicone to caulk around the
8.
pipe.
Remove the 54mm white pipe and insulation from inside
9.
the 108mm black pipe. Keeping the reducing coupling
attached to the white 54mm pipe with no bell.
Slide non-belled black pipe into belled end of other black
10.
pipe.
With the bell facing downward cut the black pipe so it fits
11.
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.)
Cut the insulation to the angle of the roof as done with the black pipe in step 11.
12.
Slide the roof flashing over black pipe with the top of the flashing away from the cut end of the pipe.
13.
Reinsert white pipe and insulation into the black pipe with the reducing coupling toward the uncut end.
14.
Place the black pipe over the white pipe that extends from
15.
the roof, ensuring that the white pipe inside the black pipe
securely joins with the pipe extending from the roof.
Slide roof flashing down so it lies evenly on the roof,
16.
slipping its flanges under the shingles along the top edge.
Outline the flashing on the roof.
17.
Raise the flashing and apply silicone sealant inside the
18.
outline.
Slide the flashing back down, sliding the flange under the
19.
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.
Secure the top of the flashing with corrosion resistant nails
20.
or staples at each corner and along the sides at 4" – 6"
intervals.
