QUADRIFOGLIO B
B Conditioners, additives, inhibitors and antifreeze liquids can be used only and
exclusively if the producer guarantees their suitability for use in heating sys-
tems and that they do not cause damage to the boiler's heat exchanger or other
components and/or materials of the boiler and system. The use of generic
chemicals not specific for use in heating systems and/or incompatible with the
materials of the boiler and system is forbidden. Chemical conditioners must en-
sure complete deoxygenation of the water, must contain specific protection for
yellow metals (copper and its alloys), anti-fouling agents for scale at least up to
15°F, neutral pH stabilizers and, in low-temperature systems, specific biocides
for use in heating systems.
B
The unit is equipped with an antifreeze system that activates the boiler in heat-
ing mode when the system delivery water temperature drops below 6 °C. The
device is not active if the power and/or gas supply to the unit is turned off.
If necessary, for system protection use a suitable antifreeze liquid that meets
the same requirements as set out above and provided for by Standard UNI
8065.
B
Regarding domestic hot water, no type of treatment that can prevent its possi-
ble food use can be provided for.
