7.1.3 Flue pipe installation
Fig. 24 shows the proper flue gas connection with addi-
tional air equipment.
Observe the following during the installation of the flue
gas connection:
V Install a flue pipe connection with an inspection aper-
ture for cleaning.
V Fasten the flue gas connector piece to the boiler.
V Feed the connector into the flue gas system on a short,
ascending path. Avoid deflections, especially those
with an angle of 90°.
V Fasten and support connectors sufficiently.
V Since the flue pipe is only fixed into the flue gas system
and push-fitted onto the boiler flue socket, it should be
fitted very carefully so that it does not come loose.
V Only use parts of non-flammable materials for the flue
gas system.

1 Optimal position: additional air equipment in the chimney
flank
2 Alternative position: additional air equipment in the flue
gas pipe
The figures in Tab. 8 are only guide figures.
The draft depends on the diameter, height,
roughness of the chimney wall, and the tem-
perature difference between combustion
products and the outside atmosphere. We
recommend the use of a chimney liner.
V Have precise calculations carried out by a
heating engineer or flue installer.
