NOTE: While a drain connection is required in the
vent of all MVB installations, the drain can be ac-
complished in several different ways. The figures in
this manual show the drain in a vent tee, however,
this can also be accomplished using an inline collec-
tor for condensing stacks or an inline vertical or
horizontal collector available from several of the
listed vent manufacturers.
