Important
information
about
venting:
Since
the
Bubble
‐
Up®
Jr
Interactive™
unit
removes
radon
in
the
water;
the
unit
must
be
vented
carefully.
Common
practice
is
to
run
the
vent
up
past
the
roof
line
of
the
building.
An
elevated
vent
opening
provides
the
best
way
of
dissipating
the
radon
gas.
Protocols
recommend
extending
the
vent
opening
2’
above
the
highest
opening
in
the
building,
and
at
least
10’
away
from
the
nearest
opening.
It
is
recommended
to
protect
the
vent
opening
with
a
vent
screen.
