4.14 Boiler flue connection

This chapter describes how the boiler flue connections
are made.

4.14.1 Fitting the flue pipe sealing collar (accessory)

For better sealing of the boiler/flue pipe, we
recommend that you use the flue pipe
sealing collar (accessory).
B Push the flue pipe as far as possible onto the flue gas
header outlet.
B Place the flue pipe sealing collar around the flue pipe
and flue gas header outlet so that it overlaps at the
top.
B Place jubilee clips over the flue pipe sealing collar.
One of the jubilee clips must press onto the flue gas
header outlet and one onto the flue pipe.
B Tighten jubilee clips. The flue pipe sealing collar must
fit smoothly and firmly in place.
Retighten the jubilee clips if required.

(accessory)
B Weld the coupling into the flue pipe at a distance of
2 × flue pipe diameters (A) from the flue gas header.
B Fit the flue gas temperature sensor as described in the
separate installation manual.

4.15.1 Fitting the thermal insulation

The insulation provided corresponds to the boiler size.
B Arrange the lagging on the boiler block as shown in
the diagram in Fig. 38 (the figures to the left of the
boiler blocks represent the number of boiler
sections).
B Push lagging under the boiler block. The boiler
section feet are placed in the cut-outs in the lagging.
