1)Compost will be removed from the finishing drawer. Ensure that there is at least 15” in front of
the EXCEL NE 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. THE DRAIN IS REQUIRED PRIOR TO
OPERATION.
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) Competing appliances (ie. wood stove) may need a air intake installed from the outdoors. The EXCEL
NE has a passive vent. Competing appliances draw alot of air and may cause your composting toilet
vent to draw air into the building rather than venting to the outside. A 12 volt fan will be required.
6) Bends in the vent, installation near hills or overhanging trees may cause downdraft. A 12 volt fan may
be required.
1) All vent should be vertically installed.
2) Limit bends in the vent stack to no more than 2 - 45 ° bends.
THERE SHOULD BE NO HORIZONTAL SECTIONS OF VENT.
3) INSTALL VENT SO THAT IT TERMINATES 24” - 30” ABOVE
HIGHEST PEAK OF THE ROOF. If the vent is being installed 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
expanding foam or other such water-tight material. The
heavier pipe should be able to withstand the weight of
sliding snow.
4) 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.
5) 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.
6) All connectors in the vent pipe should be sealed. Use silicone
caulking to seal the connections.
7) The diffusor should be glued vertically on to the top of the
vent pipe. This assembly helps draw air up the vent pipe.
Place the vent inlet coupling into the hole for the 4” vent so that
the 1” of smaller diameter pipe is protruding into the hole in the
top of the unit. This is the first piece of the venting. Once you
have finished assembling the vent, you should run a bead of sili-
cone around the inlet coupling to prevent odor from escaping.
