WARNING
! !
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
Concentric Vent Kit
section in the Operation manual.
WARNING
! !
An open tee is optional but recommended to
use as a termination to alleviate and prevent
back pressure in the venting system.
For optimal results the open tee should be
positioned vertically.
