NEO FIRE – Technical Manual

A WATER TREATMENT IS ABSOLUTELY INDISPENSABLE FOR THE INSTALLATION OF THE PRIMARY

CIRCUIT IN THE FOLLOWING CASES:

Big installations (with high water contents).
Characteristics of the refilling water different from the hardness (TH) indicated in the previous table.
Frequent refillings of the installation with new water (because of drainings, water leaks, repairing), even if the
water has a hardness lower than 12ºF.
When the maximum volume allowed of refilling water is exceeded (see table).

A mesh filter should be installed before each boiler (mesh of 0.3 mm).

Air purging/venting:

If the boilers circuit incorporates a common vertical water manifold: place an air vent of big capacity in its
higher point.
Otherwise: it would be necessary to install an air vent of big capacity or corrosion inhibitor equipment in a high
point of the circuit behind the boilers.

Old installations

e1) Before replacing the existing boilers with new boilers, proceed to clean the installation.
If a chemical product is used, it must be compatible with the installation materials.
Drainage must be made from a low point of the installation, if possible different from the boilers’draining
point.
e2) A separator of oxides and sludge must be installed in the circuits’return, so that all the return water flow
can pass through it, allowing its draining without suspending the service.

Apply the considerations of paragraphs “a,b,c,d”.

If the circuit is in very bad conditions and the previous measures taken were not sufficient, or the cleaning of
the installation was not efficient, the solution would be to separate the boilers’circuit from the heat
emitters’circuit, so that they are independent one from the other, by means of a plate heat exchanger or
similar, according to the hydraulic diagrams included in this manual (see the corresponding paragraph).
