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.
