1.14 KITS AVAILABLE ON REQUEST.
• System shut off valves kit. The boiler is desig-
ned for installation of system shutoff valves to
be placed on delivery and return pipes of the
connection assembly. This kit is particularly
useful for maintenance as it allows the boiler to
be drained separately without having to empty
the entire system.

te dispenser reduces the formation of lime-scale
and preserves the original heat exchange and
domestic hot production water conditions.
The boiler is predisposed for application of the
polyphosphate dispenser kit.

and cocks (including gas cock), to carry out
all connections to the boiler system.
