CONNECTION TO THE HEATING PLANT
•
Read carefully the contents of this handbook, it contains important information and
instructions for installation, use, maintenance and product safety.
The manufacturer
disclaims all responsibility caused by incorrect installation, using, tampering,
maintenance or no respect of normative in force.
•
The installation and the connection of the equipment to the heating plant as singular or
with others heating equipment ( es. gas boiler, solar panel, termo-chimney …) must
be done by qualify staff who can carry out a perfect work and who can release the
conformity certification according to normative in force in the country of installation.
•
Technological connection and appliance installation must be carried out
EXCLUSIVELY by a qualified staff, who is authorized to release a conformity
certificate according with the normative in force and current standards.
•
In case the appliance is used in pairing with other types of appliances or heating
plants, the installer should prearrange all possible expediencies to solve compatibility
problems.
•
Cut-off cocks must be installed out of the appliance, which permits to insulate the
appliance in case the thermal plant should be disconnected for maintenance and/or
repair purposes.
•
Flexible tubes are preferred to connect the appliance to the plant.
•
Water or steam exhaust tubes and safety pipings must must release in an adequate
place in order to avoid damages to the appliance or the the installation place.
•
In order to avoid problems arising from residuals and/or deposit it is deeply
recommended to effect a complete washing of the plant (specially by new plants)
before connecting the appliance.
•
The installation of the appliance must be effected with an open expansion tank
:
An Over-pressure Valve (3bar) must be applied to the plant as well as a visualizer of
the boiler water temperature. All safety devices must be accessible also after the
installation, in order to allow an easy maintenance and the control of their functioning.
•
We recommend to regulate the starting control of the circulator (pump) so that the
water begins to circulate at a temperature of 55° - 60°C, lower temperature could
create condensate on the wall of the boiler.
•
It is strictly forbidden to use the appliance if it is not connected to a functioning
heating plant.
•
The connection of the appliance to the thermal plant should also foresee a cock for the
emptying of the boiler. This cock should be placed on the backflow tube and, if
possible, connected to the a sink.
•
All safety devise or cock during the functioning must be open
.
•
The installation water should have some chemical and physical characteristics for a
good functioning of the equipment for a long time. The feeding water of bad quality
could cause problems as incrustations of the thermic exchange surfaces and
sometimes the corrosion of water surfaces of the complete circuit. The presence of
chalky incrustation penalize a lot the thermic exchange and dangerous overheating
could be caused. Here follow some examples to make treatment for water :
Water
hardness > di 20°f ; Heating plan with open expansion tank; Frequent water
introduction due to lacks or maintenance operation.
•
Call a qualify company for the water treatment of thermic plan.
