1.17 KITS AVAILABLE ON REQUEST.
• System shut off valves kit. The boiler is designed
ES
for installation of system interception cocks
to be placed on flow and return pipes of the
connection assembly. This kit is particularly
PT
useful for maintenance as it allows the boiler to
be drained separately without having to empty
the entire system.
• System zone control unit Kit. If the central
GR
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
PL
zone system kits on request.

• Polyphosphate dispenser kit. The polyphos-
phate dispenser reduces 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.
• C over kit. For outdoor installations, in partially
protected areas and with direct air intake, the
top protection cover must be fitted for a cor-
rect functioning of the boiler and to protect it
from storms (Fig. 1-8). For indoor installations,
type B configuration, a suitable top protection
cover coupled with the flue exhaust kit must be
fitted.
• Anti freeze kit with resistance (on request). If
the boiler is installed in a place where the tem-
perature falls below -5°C and in the event there
is no gas, the appliance can freeze. To prevent
freezing of the domestic hot water system, an
anti freeze kit with an electrical resistance can
be fitted from the relative cable and from a
control thermostat.
• External storage tank unit coupling kit. If the
production of DHW is required as well as room
central heating, on request Immergas supplies
a kit made up from an external cylinder unit
and everything necessary for adaptation of the
boiler
The above-mentioned kits are supplied complete
with instructions for assembly and use.
