FORCE B
System water characteristics
Before installing the FORCE B generator, the new or existing system must be properly cleaned in order to eliminate
installation residues, solvents, sludge and contaminants in general that may compromise the effectiveness of the pro-
tective conditioning treatments. Use neutral cleaning products that do not attack metals, rubber and plastic parts of the
generator/system. Empty, wash and recharge the system in compliance with the following instructions. A dirty system
will not guarantee the life of the generator over time, even with the use of protective conditioners.
B
FORCE B boilers are suitable for installation in heating systems with non-signifi-
cant entry of oxygen (ref. systems "case I" EN14868). A physical separator (e.g.
plate heat exchanger) must be provided in systems with continuous entry of oxy-
gen (e.g. underfloor systems without anti-diffusion pipes or open vessel), or fre-
quent (frequent water replenishment).
The water in a heating system must be treated in compliance with the laws and re-
gulations in force, have the characteristics required by UNI 8065, and comply with
the provisions of EN14868 (protection of metallic materials against corrosion).
The filling water (first filling and subsequent replenishments) must be potable, clear, with hardness under the values
indicated in the table below and treated and conditioned with chemical conditioners declared suitable by the maker (see
following list), in order to prevent encrustations, corrosive or aggressive phenomena on the metals and plastics of the
generator and system, the formation of gas, and the proliferation of bacterial or microbial masses in low temperature
systems.
The water contained in the system, as well as the replenishment water, must be checked periodically (at every start-up
of the system, after any non-scheduled intervention such as, for example, replacement of the generator or other system
components, as well as at least once a year during mandatory routine maintenance operations as required by UNI
8065). The water must have a clear appearance and respect the limits given in the following table.

* In the presence of conditioners, the limit increases to 1200 µS/cm.
In case of differing values or difficult checking of values with conventional analysis/testing procedures, contact the com-
pany for additional evaluations. The conditions of the feed water to be treated can vary even significantly depending on
the geographical areas where the systems are located.
Chemical conditioners deoxygenating, anti-scaling, corrosion inhibiting, anti-bacterial, anti-algae, frost protection, PH
correction products, etc., must also be suitable for the materials of the generator and system. They must be put in the
system respecting the quantity indicated by the supplier of the chemical product and checked in their concentration.
B
A chemical conditioner in insufficient concentration will not be able to ensure the
required protection.
Always check the product concentration each time it is added and cyclically, at
least once a year, using qualified technical personnel such as our authorized tech-
nical assistance network.
