ANTI-CONDENSATION VALVE KIT CONNECTION (OPTIONAL)
It is essential for these types of boilers to mount a mixing valve
calibrated at 56 °C (see optional kit); this prevents the return
of water too cold in the boiler, thus preventing the forming
of condensate and corrosion, which inevitably cause a rapid
deterioration of the thermal exchange surfaces, thus extending
the life of the boiler.
Description of operation:
The anti-condensation valve integrates a thermostatic cartridge
which closes passage “A” (return) until the boiler water (which
recirculates from passage “B” of the valve) reaches the nominal
temperature (56 °C).
Once the nominal temperature is reached, the thermostatic
cartridge begins to gradually open the system return circuit
“A” (cold) mixing it with the system flow “B” (hot), ensuring
a nominal temperature to the “AB” generator (boiler return).
ATTENTION:
All LUXOR models are EN 303-5 certified and
have overcome the safety tests provided by the standard, having
in particular met the test referred to in point 5.14 (“rapid dis-
connection system”). It is, therefore, not necessary to provide
coils or thermal safety discharges.

NOTE:
the above figure represents the LUXOR 20-24-28-33
models, as for the LUXOR 16 model, the system flow and return
are inverted in position with respect to all other models.
Always install shut-off valves on the system flow and return for
easy routine and/or extraordinary maintenance. In addition it
is also necessary to install a draining valve to empty the boiler.
