B23 Upstream fan. Comburent air intake directly
from the room where the boiler is installed. Flue
gas vent via horizontal or vertical flues, with air
ventilation to room.
B23P As B23 but with flue gas vent designed to opera-
te at positive pressure.
B53 Upstream fan. Comburent air intake directly
from the room where the boiler is installed. Flue
gas venting via dedicated pipes. Air ventilation
to room.
B53P As B53 but with dedicated flue gas vent desig-
ned to operate at positive pressure.
C13 Concentric wall vent. Twin flue pipes can also be
used, but the wall through-pipes must be con-
centric or located close enough to be subjected
to similar wind conditions.
C33 Concentric roof vent. Outlets as for C13.
C43 Vent and air intake via shared twin pipes,
subjected to similar wind conditions.
C53 Separate wall or roof vent and air intake, in are-
as of different pressure but never on opposite
