NOTE: When stacking a CNV 8E with a COS 8E,
COS 8EDS or BCS 8E the drains must not
be manifolded together.
NOTE: The installation plumber is responsible for
connections between units and connec
tion to the drain. Use a 24" section on the
top unit Tee to raise the breather vent. This
will prevent overflow if both units are flush
ing simultaneously.
