field of installation and maintenance of components for central heating and domestic hot water production systems for domestic and industrial use.
The appliance must be used solely for the purpose for which it has been designed and
manufactured: central heating and domestic hot water production. Any other use is deemed as improper and as such dangerous. Under no circumstances will the manufacturer be held responsible for damage or injury to persons or animals caused by errors in the installation and/or use of the appliance, or through non-compliance with current local and national standards and/or the manufacturer’s instructions.
The installation, operation and maintenance manual forms an integral and essential part of the
product and must be kept near the appliance always.
This manual must be kept in a safe place and made available for any future reference. If the
appliance is sold or transferred to a different owner, this must follow the appliance to be red by the new owner and/or installer.
The warnings contained in this chapter have been written for the appliance user, the installer and
the service engineer.
The user manual must be red carefully as it provides information on the operation and the
operating limits of the appliance.
This appliance must be used exclusively in a pressurised central heating system.
After the removal of all the packaging, check that the appliance has not been damaged. In case of doubt, do not attempt to use the product but refer to the supplier. Packing materials (cardboard box, wooden crate, nails, staples, plastic bags, polystyrene, etc.) must not be left within reach of children in that these items represent a potential hazard and must be disposed of in a responsible manner.
Before carrying out any cleaning or maintenance operations, disconnect the appliance from the mains electricity supply by switching off at the main switch and/or any other isolating device.
Do not obstruct the air intake or flue exhaust grills.
Do not obstruct the air intake or flue exhaust terminals.
In the case of a fault and/or malfunction in the appliance, shut down the system. Do not interfere with or attempt

3.4 Installing the boiler
The appliance must be installed exclusively on a flat vertical solid wall capable of supporting its weight.
The boiler should be fitted within the building unless otherwise protected by a suitable enclosure i.e. garage or outhouse. (the boiler may be fitted inside a cupboard.
If the boiler is sited in an unheated enclosure then it is recommended to leave the power on to give frost protection (frost protection is active even with on/off switch in off position).
If the boiler is installed in a room containing a bath or shower reference must be made to the relevant requirements.
In order to allow access to the interior of the boiler for maintenance purposes, it is important that the necessary clearances indicated in figure 1 are respected. To make the installation easier, the boiler is supplied with a template to enable the pipe connections to be positioned prior to fixing the appliance to the wall.
To install the boiler, proceed as follows (see fig. 2): a. Use a spirit level (of not less than 25 mm
long) to mark a horizontal line on the wall where the boiler is to be fitted.
b. Position the top of the template along the
line drawn with the level, respecting the distances indicated. Then mark the centres of the positions of the two wall­plugs or anchors. Finally, mark the positions of the water and gas pipes.
c. Remove the template and install the
domestic hot and cold water pipes, the gas supply pipe and the central heating pipes using the fittings supplied with the boiler.
Fix the boiler to the wall using the wall plugs or bracket and connect the pipes.

3.5 Water connections
In order to safeguard the heat exchanger and
circulation pump, especially in case of boiler replacement, it is recommended that the system is hot-flushed to remove any impurities (especially oil and grease) from the pipes and radiators.
Make sure that the domestic water and central
heating pipes are not used to earth the electrical system. The pipes are totally unsuitable for this purpose.
Isolation Valves must be installed on the heating
and D.H.W circuits. This will facilitate all maintenance and service operations where the boiler needs to be drained.
To prevent vibration and noise coming from
the system, do not use pipes of reduced diameter,
short radius elbows or severe reductions in the cross sections of the water passages.
To facilitate the installation, the boiler is supplied with
an hydraulic connection kit (see fig.2).
Domestic hot water circuit
In order to prevent scaling and eventual damage to the
D.H.W heat exchanger, the mains water supply must not have a hardness rating of more than 17.5 °Ck. It is nevertheless advisable to check the properties of the water supply and install the appropriate treatment devices where necessary.
The cold water supply pressure at the inlet to the boiler must be between 0.5 and 6 bar.
In areas with higher water inlet pressure a pressure reducing valve must be fitted before the boiler.
The frequency of the heat exchanger coil cleaning depends on the hardness of the mains water supply and the presence of residual solids or impurities, which are often present in the case of a new installation. If the characteristics of the mains water supply are such that require it to be treated, then the appropriate treatment devices must be installed, while in the case of residues, an in-line filter should be sufficient.
All D.H.W. circuits, connections, fittings, etc. should be fully in accordance with relevant standards and water supply regulations.
Central heating circuit
In order to prevent scaling or deposits in the primary heat exchanger, the mains supply water to the heating circuit must be treated according to the requirements of local standards. This treatment is indispensable in the case where the circuit is frequently topped-up or when the system is often either partially or fully drained.
The outlet connection of the boiler safety valve must be connected to a discharge trap. The manufacturer will not be held responsible for flooding caused by the operation of the safety valve in the case of system overpressure.
