1.18 KITS AVAILABLE ON REQUEST.
• System shut o valves kit. e boiler is desig-
ned for installation of system shut o valves to
be placed on delivery and return pipes of the
connection assembly. is kit is particularly
useful for maintenance as it allows the boiler to
be drained separately without having to empty
the entire system.
• a) Polyphosphate dispenser kit for wall instal-
lation.
• b) Polyphosphate dispenser kit for installation
with recess frame.
e polyphosphate dispenser reduces the for-
mation of lime-scale and preserves the original
heat exchange and domestic hot production
water conditions. e boiler is prepared for
application of the polyphosphate dispenser kit.
• Covering kit. For outdoor installations, in
partially protected areas and with direct air
intake, the top protection cover must be tted
for a correct functioning of the boiler and to
protect it from storms (Fig. 1-8). For indoor
installations, type B conguration, a suitable
top protection cover coupled with the flue
exhaust kit must be tted.
• 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 tted from the relative cable and from a
control thermostat.
• Installation kit with recess frame. Using a
suitable recess frame, it is possible to t the
boiler inside the wall, conguration type C, or
with direct outdoor air intake, thanks to the
ventilated recess frame.
• a)- Attachment kit for wall installation.
• b)- Attachment kit for recess boiler.
e kit includes pipes, ttings and cocks (inclu-
ding gas cock) for the connection of the boiler
to the system and 4 spacers to be used under
the side plugs of the sealed chamber (the plugs
are recess type).
N.B.: for recess tting, using the same kit (b),
it is possible to carry out front installation or
back installation exiting the recess frame.
e above-mentioned kits are supplied complete
with instructions for assembly and use.
