Configurations
Special kits are available to enable
Novella
boilers to be installed in modular systems (i.e.
in cascades) (fig. 8.1).
The modular configurations listed in the fol-
lowing table can be formed using the kits
specified.
Figure 8.2 provides a possible schematic
for the connection of two
Novella
boilers in
a system that only provides central heating
(fig. 8.2).
This configuration provides a total heat output
equivalent to the sum of the heat outputs of
its two
Novella
boilers. The functioning of the
system can be controlled (modulated) from
the control panel.
