If these directions and those of the appliance
manufacturer differ, follow the more
conservative requirements. If you have any
questions, contact either your dealer or
DuraVent directly. A venting system must
not be routed into, through, or within any
other vent, such as an existing masonry or
factory-built chimney flue, unless that vent
or chimney is not being used to vent another
appliance and is only used as a conduit for
the gas-vent system. Plastic venting systems
shall not pass through fire rated separations
without approved firestopping.
