1.19 KITS AVAILABLE ON REQUEST.
• System cut-off valves kit. The boiler is designed for installation
of system interception cocks to be placed on flow 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.
• Polyphosphate dispenser kit. The polyphosphate dispenser re-
duces the formation of lime-scale and preserves the original heat
exchange and domestic hot water production conditions. The
boiler is prepared for application of the polyphosphate dispenser
kit.
N.B.:
this is a type of chemical conditioning treatment for do-
mestic hot water, if provided for by current regulations.
• System zone control unit Kit. If the central 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.
The above-mentioned kits are supplied complete with instructions
for assembly and use.
