1.18 KITS AVAILABLE ON REQUEST.
• Kit of system shutoff valves (on request). The
boiler is designed 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.
• System zone Kit (on request). If the heating
system is to be divided into several zones (
max.
three ), in order to interlock them with separate
adjustments and to keep water flow rate high
for each zone, Immergas supplies zone system
kits by request.
• Polyphosphate batching kit (on request). The
polyphosphate dispenser Reduces the forma-
tion of lime-scale and preserves the original
heat exchange and domestic hot production
water conditions. The boiler is prepared for
application of the polyphosphate dispenser kit.
The above kits are supplied complete with in-
structions for assembly and use.
