Vent Pipe

Location

1.Compost will be removed from the finishing drawer. Ensure that there is at least

15” in front of the SPACESAVER 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.

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 SPACESAVER Toilet is protected from precipitation.

7. Ensure that the unit is installed on a level surface or sloping slightly towards the

back.

1. If running a vent through a wall, it should be done at a 45° angle to prevent con-

densation from accumulating in the vent pipe, causing a constriction. 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 in-

sulated 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 sub-

stance. 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 above the 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 for 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.

Leading the vent through the roof Leading the vent through the wall The Diffusor Drain Installation The vent stack (shown in diagram) should end approximately 30” above the peak of the roof so that it is less subject to downdraft. Where the pipe is taken through the roof, a roof flashing may be required to seal the installation. If you are in an area where snow shear is a danger, you may wish to install a heavier pipe around the vent pipe where it exits from the roof.
