Installation Considerations
Vent Pipe
Location
1)Compost will be removed from the finishing drawer. Ensure that there is at least 15” in front
of the Self Contained Toilet so that the drawer may be removed from the unit.
2) Install the unit in a location where the safety drain can be connected if required. This drain
exits from the back of the unit and must slope downward at all points.
3) Install in a location where the vent pipe can be attached as per the instructions listed below.
4) Install in a location that is not air tight.
5) Ensure that there is a three-pronged plug with a GFI (ground fault interrupter) installed
within 5 feet of the unit.
6) Ensure the Self Contained Toilet is protected from precipitation.
1) If running a vent through a wall, it should be done at a 45° angle to prevent condensation
from accumulating in the vent pipe, causing a constriction. THERE SHOULD BE NO
HORIZONTAL SECTIONS OF VENT. Venting should be installed vertically.
2) All vent pipe that is exposed to the outside or in a non-heated space should be insulated if
using the unit during cold weather.
3) INSTALL VENT SO THAT IT TERMINATES 24” - 30” ABOVE HIGHEST PEAK OF THE ROOF.
4) If you will be installing venting on a steeply pitched roof where snow shear may occur;
Install a heavier pipe through the roof and feed the enclosed vent through the heavier pipe.
Seal between the pipes with expandable foam or other such water-tight substance. The
heavier pipe should be able to withstand the weight of sliding snow.
5) If there is more than 36” of vent needed above the roof line to reach 24-30” above the
highest peak of the roof (diffusor included in measurement), use guy wires to secure the
vent abovethe roof.
6) Limit bends in the vent stack to no more than 4 that have a combined total of 180 °.
7) The vent must be installed separately from ALL other household vents. Venting cannot be
merged with other venting. Doing so will prevent the unit from operating odorlessly.
8) All connectors in the vent pipe should be sealed. Use silicone caulking to seal the
connection between the vent and the fan. PVC cement may be used all other vent
connections.
9) The diffusor should be glued vertically on to the top of the vent pipe. This assembly helps
draw air up the vent pipe.
