Is it ok to connect a piece of rigid direct vent pipe to a piece of flexible pipe?

Our Answer:

In regards to the Simpson DirectVent Pro piping, it is necessary to use either all rigid or all flexible piping. While the connection between the two can be made, the manufacturer does not test their components in this way and does not approve their use together.
