Note: The gap drain is not designed to catch the maximum discharge pos-
sible from the relief valve. The installation of FEBCO air gap with the drain
line terminating above a floor drain will handle any normal discharge or nui-
sance spitting through the relief valve. However, floor drain size may need
to be designed to prevent water damage caused by a catastrophic failure
condition. Do not reduce the size of the drain line from the air gap fitting.
* The wetted surface of this product contacted by consumable water con-
tains less than one quarter of one percent (0.25%) of lead by weight.
