The window in the picture
(right side) is not 10' away from the discharge point;
therefore, the Radon reduction system must discharge
2' above the window to meet the standards.
In certain applications, it
is necessary to extend the roof discharge point to the
higher roof line to discharge above windows. This picture
shows the roof flashing (roof jack) set to seal the
roof. The 4" PVC pipe extending out of the roof
jack is converted via a downspout adaptor to receive
the downspout (4" x 3") that aesthetically
allows the discharge point to release at a higher point.
Note the roof top attachment is on the down slope of
the roof and can not be seen from the street. This is
an extra adaptation created by ASEC to remedy problems
associated with roof top discharges.
