Information and specifications for installing
the B23P
Pipe lengths in the B23P installation (→ Page 42)
The flue gas system must at least correspond to the classi-
fication T 120 P1 W 1 in accordance with EN 1443.
The maximum pipe length (straight pipe only) corresponds to
the maximum permitted flue gas pipe length without any el-
bows. If elbows are used, the maximum pipe length must be
reduced in accordance with the dynamic flow characteristics
of the elbows. Elbows must not be connected directly after
one another as this method dramatically increases pressure
losses.
In particular, if the flue pipe is installed in cold rooms or out-
side of the building, the freezing point on the surface of the
inside of the pipe may be reached. A proven design in ac-
cordance with EN 13384-1 for a maximum boiler load at a
flue gas temperature of 40 °C must be used to prevent this
problem. The product must not be connected to a cascade
flue gas system that is being used by other units.
▶
Observe the applicable international, national and local
regulations for flue gas systems, in particular for installa-
tions in living rooms. Inform the operator how to correctly
operate the product.
