Vitoradial 300-T condensing boilers may be connected to a moisture-
resistant chimney, if the chimney manufacturer can provide a calcula-
ted verification to DIN EN 13384.
A flue pipe that is pressure sealed and moisture-resistant in accord-
ance with Building Regulations should be used as connecting piece.
Plewa or Schiedel (quoting reference "Schiedel Steck-Adapter") sup-
ply this adaptor from the flue pipe to the MR chimney upon request.
