3.2.9. Plumbing connections
Prior to installing the boiler, the plumbing system nust be cleaned thoroughly to remove impurities from the components, which could
damage the pump and heat exchanger (§ 3.2.4.).
CH pipes
The flow and return pipes in the CH system must be connected to their respective 1” fittings (
M
and
R
) on the boiler (Figs. 6 and 7).
When calculating the cross-section of CH pipes, it is important to take into account load losses due to the length of the pipe, the CH
terminals and the configuration of the system.
The cold water inlet must be connected to the ½” fitting (F) of the boiler (Figs. 6 and 7).
CONDENSATE DRAINAGE
Comply with condensate drainage laws and standards in force in the country of installation, which are intended as an integral part of this
handbook.
When not specifically prohibited by law, the condensate produced by combustion must be conveyed (via the condensate drain - S in
Fig. 5) to a drainage system connected to the disposal system for domestic sewage, which due to its alkalinity offset the acidity of the
condensate.
To prevent unpleasant odours from the domestic drains, it is advisable to install a separation device between the condensate drainage
system and the domestic waste system.
The condensate drainage system and the domestic waste system must be made of suitable materials that are resistant to the condensate.
The Manufacturer cannot be held liable for damage or injury caused by failure to comply with the above instructions.
3.2.10. Power mains connection
The boiler is supplied with a three-pole power cable, connected at one end to the electronic board and protected from tearing by a clam-
ping system.
The boiler must be connected to a 230V-50Hz mains supply.
When connecting the boiler, keep to the correct phase / neutral polarity sequence.
The installation must comply with the applicable laws in the country of installation, which are intended as an integral part of this handbook.
An easy-access two-pin switch with at least 3mm between the contacts must be installed before the boiler to enable the power supply
to be cut off, so that maintenance can be performed in complete safety.
The power supply to the boiler must be protected by a differential magnetic-thermal automatic switch of appropriate shut-down capacity.
The mains supply must be appropriately earthed. This is a vital safety requirement. When in doubt, have the electrical system checked
thoroughly by a qualified electrician.
The Manufacturer shall not be held liable for damage or injury resulting failure to earth the system properly. Gas, water and
CH pipes must NOT be used for earthing.
