WARNING
Asphyxiation Hazard. Vent systems made by
M&G/DuraVent and Centrotherm Eco Systems
rely on gaskets for proper sealing. When these
vent systems are used, take the following
precautions:
• Make sure that gasket is in position and un-
damaged in the female end of the pipe.
• Make sure that both the male and female
pipes are free of damage prior to assembly.
• Only cut vent pipe as permitted by the
vent manufacturer in accordance with their
instructions. When pipe is cut, cut end
must be square and carefully de-burred prior
to assembly.
• Use locking band clamps at all vent pipe
joints.
