In case of concentric venting system:
As an alternative to twin pipe venting, a purposely designed and built
telescopic concentric vent kit can be obtained as an accessory from
Bosch Thermotechnology for a horizontal direct vent wall termination.
This vent system can be used for vent lengths of 2 feet to 3 feet (610 mm
to 915 mm).
For more details on connecting the flue system, refer to the installation
