• If the boiler is equipped with an electronic thermostatic controller fitted in position 1 of fig. 1, the user must also take into account the manufacturer’s instructions.

If the burners do not light and the button-shutdown indicator 5 comes on after correctly carrying out the lighting procedures, wait about 15 seconds and then press the above-mentioned button. The flame controller reset in this way will then repeat the lighting cycle. If the burners do not light after several attempts, consult the faults section
In case of a power failure while the boiler is working, the burners will go out and relight automatically when the power is restored.

Turning off
Close the gas cock ahead of the boiler, turn knob “7” to 0 and disconnect the power.
To avoid damage caused by freezing during long idle periods in winter, it is advisable to drain all water from the boiler, DHW circuit and system; or add a suitable antifreeze  o the heating system.
The boiler switch “7” has 3 positions “0-1-TEST”; the first two have the on- off function, the third (unstable) must only be used for service and maintenance purposes.
2.4 Adjustments
System temperature adjustment
Turn the knob 6 of fig. 1 clockwise to increase the heating water temperature, or anticlockwise to decrease it. The temperature can be varied from a minimum of 30°C to a maximum of 90°C. However, it is advisable not to operate the boiler below 45°C.
Room temperature adjustment (with optional room thermostat)
Using the room thermostat, set the temperature required in the rooms. By room thermostat command, the boiler lights and brings the system water to the temperature set by boiler control thermostat 6 of fig. 1. The generator goes off when the required temperature in the rooms is reached. If the room thermostat is not installed the boiler will keep the system at the temperature set by the boiler control thermostat.
Water system pressure adjustment
The filling pressure with system cold, read on the boiler water gauge detail 2 of fig. 1, must be approx. 1.0 bar. If, during operation, the system pressure falls (due to the evaporation of gases dissolved in the water) to values below the minimum described above, the user must bring it to the initial value by operating the filling cock. At the end of the operation always close the filling cock.
2.5 Faults
Given below are the faults that can be caused by simple user-solvable problems.

INSTALLATION
3.1 General Instructions
This unit must only be used for its intended purpose. This unit is designed to heat water to a temperature below boiling point at atmospheric pressure and must be connected to a heating system and/or a water supply system for domestic use, compatible with its performance, characteristics and its heating capacity. Any other use is considered improper. THE BOILER MUST ONLY BE INSTALLED BY QUALIFIED PERSONNEL, IN ACCORDANCE WITH ALL THE INSTRUCTIONS GIVEN IN THIS TECHNICAL MANUAL, THE PROVISIONS OF CURRENT LAW, ANY LOCAL REGULATIONS AND THE RULES OF PROPER WORKMANSHIP.
The Manufacturer declines any liability for damage or injury caused by incorrect installation.
3.2 Place of installation
This unit is an “open chamber” type and can only be installed and operated in permanently ventilated rooms. An insufficient flow of combustion air to the boiler will affect its normal operation and fume evacuation. Also, the fumes forming in these conditions (oxides) are extremely harmful to the health if dispersed in the domestic environment. Therefore the place of installation must be free of dust, flammable materials or objects or corrosive gases. The room must be dry and not subject to freezing. When positioning the boiler, leave sufficient space around it for normal maintenance activities.
3.3 Plumbing connections Instructions
The heating capacity of the unit must be previously established by calculating the building’s heat requirement according to the current regulations. For proper operation and long life of the boiler, the plumbing system must be adequate and complete with all accessories that guarantee regular operation and running. If the delivery and return pipes follow a path where air pockets could form in certain places, it is advisable to install vent valves at these points. Also, install a discharge device at the lowest point in the system to allow its complete emptying. If the boiler is installed at a lower level than the system, it is advisable to provide a flowstop valve to prevent the natural circulation of system water. The temperature drop between the delivery manifold and the return to the boiler should not exceed 20°C.
Do not use the water system pipes to earth electrical appliances.
Before installation, carefully wash all the pipes of the system to remove any residuals or impurities that could affect proper operation of the unit.
Carry out the relevant connections as indicated in fig. 10.
It is advisable to install on-off valves between the boiler and heating system allowing the boiler to be isolated from the system if necessary.
Make the boiler connection in such a way that its internal pipes are free of stress.
Water system characteristics
In the presence of water harder than 25° Fr, it is advisable to use suitably treated water, in order to avoid possible scaling in the boiler caused by hard water, or corrosion produced by aggressive water. Due to its low thermal conductivity, scaling even just a few mm thick causes significant overheating of the boiler walls with consequent serious problems. Water treatment is indispensable in case of very large systems (containing large amounts of water) or with frequent introduction of replenishing water in the system. If partial or total emptying of the system becomes necessary in these cases, it is advisable to refill with treated water.
Filling boiler and system
The filling pressure with system cold system must be approx. 1 bar. If, during operation, the system pressure falls (due to the evaporation of gases dissolved in the water) to val- ues below the minimum described above, the user must bring it to the initial value. For correct operation of the boiler, when hot, its pressure must be approx. 1.5-2 bar.
3.4 Gas connection
Before carrying out the connection, make sure the unit is arranged for the type of fuel available and carefully clean all the system gas pipes to remove any residues that could affect proper boiler operation. The gas must be connected to the relevant connection (see fig. 10) in conformity with the current standards, with a rigid metal pipe or with a continuous flexible s/steel tube, installing a gas cock between the system and boiler. Make sure all the gas connections are tight.
The capacity of the gas meter must be sufficient for the simultaneous use of all equipment connected to it. The diameter of the gas pipe leaving the boiler does not determine the diameter of the pipe between the unit and the meter; it must be chosen according to its length and pressure losses, in conformity with the current regulations.
Do not use the gas pipes to earth electrical appliances.
3.5 Electrical connections Connection to the power supply
The boiler must be connected to a single-phase, 230 Volt-50 Hz electric line.
The unit’s electrical safety is guaranteed only when it is correctly connected to an efficient earthing system in conformity with the current safety regulations. Have the efficiency and suitability of the earthing system checked by professionally qualified personnel; the Manufacturer declines any liability for damage caused by failure to earth the system. Also make sure the electrical system is adequate for the maximum power absorbed by the unit, as specified on the boiler dataplate, in particular ensuring that the section of the system’s cables is suitable for the input.
The boiler is prewired and supplied with a connector located inside the control panel, arranged for connection to an electronic thermostatic controller (see wiring diagrams in sec. 5.5). It is also equipped with a three-core cable for connection to the electric line. The connections to the power supply must be made with a permanent connection and equipped with a double-pole switch with contact gap of at least 3 mm, interposing fuses of max. 3A between the boiler and line. It is important to respect the polarities (LINE: brown wire / NEUTRAL: blue wire / EARTH : yellow/green wire) when making the connections to the electric line.
