WARNING
!
!
An open tee is optional and can be
used as a termination to alleviate back
pressure in the venting system in areas
experiencing abnormally high winds.
The Grand Hall approved concentric kit is a unique
pipe-in-pipe venting system designed for termination.
Do not try to replicate or make your own. For more
information, please refer to
