:
The FujiClean Treatment System must be vented. In most cases, the system will vent
through the building’s septic discharge pipe and building plumbing. In cases where there is a
blocked air way (e.g. effluent pump), or in severe downdraft locations, a separate vent should be
installed. If you install a vent, be sure that the vent pipe slopes toward the tank so that any
moisture accumulation drips toward the tank.

3” port for optional air vent line. If not used,
install plug in port by turning clockwise to tighten.
(Note: There are 2 ports in CE14, CE21, CE30,
CEN14 and CEN21).
If an air vent line is installed, slope
conduit toward tank to prevent
moisture accumulation.

Additional Venting Notes and Tips:
Local regulations may specify required vent pipe diameter
Keep horizontal vent pipe as short as possible. Vertical pipe length should be 2 times longer
than horizontal
Installation of a positive flow ventilation fan allows for better ventilation
Greater temperature differential between tank and outside air allows for more effective
ventilation
