Additional requirements for UL/ULC-listed flexible vent system / connector pipe vent material

Exhaust vent/air intake connection to boiler

The vent/air intake connection to the Vitodens boiler
must be made according to the table below. The starter
adaptors are intended for a slip fit and slide into the
parallel adaptor or boiler adaptor with a gentle twisting
motion.
For air intake pipe system, one wire mesh screens (bird
screen) must be ordered from Viessmann. These parts
are available in pre-cut diameters of 2 in., 3 in. and 4 in.

Direct Venting (Two-pipe System)
Note: The Vitodens boiler has passed the zero inches vent
clearance to combustibles testing requirements
dictated by the Harmonized Standard ANSI Z21.13.
CSA 4.9. and therefore is listed for zero clearance
to combustibles when vented with a single pipe
special venting system.
WARNING
The use of vent material other than listed flexible PP(s),
positive pressure vent pipe and fittings can cause property
damage, severe personal injury and/or loss of life.
