Earthing of the pellet hoses is also required for
the manually actuated variant of the diverter
for suction heads (Art. 68190).
6 Hydraulic equipment
Various hydraulic variants are available for the
pellet
elegance
boiler.
Up to two heating circuits and a switching valve can
be optionally integrated into the boiler for the purpose
of charging the DHW tank.
The basic equipment is installed in the boiler at the
factory, while the optional extras are installed on site.
i
If the
pellet
elegance
boiler is installed with a
condensing module, we recommend installing
the condensing module BEFORE installing
the hydraulic extensions (for better acces-
sibility during installation).
