Note
The flue connecting from the appliance to the flue
system must be supplied from the manufacturer of
the boiler.
C43 flue systems must not be a 'pressurised sys-
tem' but act under natural draught principles.
C43 type flue systems must have their own con-
densate drain fitted and not allow condensate to
mix into other appliances.
The flue length must be calculated and installed according
to the relevant standards EN 13384-1 and 2 (C43 flue sys-
tems only) with reference to the table below and the manu-
facturer's instructions supplied. The appliance maximum flue
length must be included when calculating the overall design
of the flue system.
Each time an additional 90° bend is necessary (or 2 at 45°),
the length (L) must be reduced (see table below).
