Characteristics of the system water
In the presence of water harder than 25° - 30° Fr, we recommend the use of suitably conditioned
water for the heating system in order to avoid possible scaling in the boiler, caused by hard water,
or corrosion produced by aggressive water. It should be remembered that, because of its low
thermal conductivity, even scaling of just a few mm thick causes signifi cant overheating of the boiler
walls with consequent serious problems.
Water treatment is indispensable for the heating system in the following cases:
A)very large systems (containing large amounts of water):
B) frequent introduction of replenishing water in the system, in the case of draining the
system either partially or totally.
Positioning the module generators and connecting the fl ues to the manifold
The set of module generators can comprise at most 4 units; depending on controller requirements they
can be arranged with the modules either facing each other or in a line.
Position the generators and connect the fume extraction pipes according to the diagrams and data
given in the charts of Fig. 8 - 9. Seal the various pipe joints.
