Heating Capacity Adjustment (RANGE RATED)
This boiler is "RANGE RATED" (in accordance with EN 483) and can be
A
adapted to the heating requirements of the system by setting the maximum
heating capacity for heating mode, as follows:
• Put the boiler in TEST mode (see sec. 4.1).
• Press the heating buttons (details 3 and 4 - fig. 1) to increase or decrease the power (min.
= 00 - max. = 100). See the diagram "Heating Capacity Adjustment" (fig. 39).
• By pressing the reset button (detail 8 - fig. 1) within 5 seconds, the maximum heat-
ing capacity will remain that just set. Exit TEST mode (see sec. 4.1).

Checks to be made at first lighting, and after all maintenance operations that
involved disconnection from the systems or an operation on safety devices or
parts of the boiler:
Before lighting the boiler
• Open any on-off valves between the boiler and the systems.
• Check the tightness of the gas system, proceeding with caution and using a soap
and water solution to detect any leaks in connections.
• Check correct prefilling of the expansion tank (ref. sec. 5.4).
• Fill the water system and make sure all air contained in the boiler and the system
has been vented, by opening the air vent valve on the boiler and any vent valves on
the system.
• Fill the condensate trap and check correct connection of the condensate elimination
system.
• Make sure there are no water leaks in the system, DHW circuits, connections or boiler.
• Check correct connection of the electrical system and efficiency of the earthing system
• Make sure the gas pressure value for heating is that required.
• Make sure there are no flammable liquids or materials in the immediate vicinity of
the boiler
Checks during operation
• Turn the unit on as described in sec. 2.3.
• Make sure the fuel circuit and water systems are tight.
• Check the efficiency of the flue and air-fume ducts while the boiler is working.
• Check the correct tightness and functionality of the condensate elimination system
and trap.
• Make sure the water is circulating properly between the boiler and the systems.
• Make sure the gas valve modulates correctly in the heating and domestic hot water
production phases.
• Check proper boiler lighting by doing several tests, turning it on and off with the room
thermostat or remote control.
• Using a combustion analyser connected to the boiler fume outlet, check that the
CO content in the fumes, with the boiler operating at max. and min. output, corre-
2
sponds to that given in the technical data table for the corresponding type of gas.
• Make sure the fuel consumption indicated on the meter matches that given in the
technical data table on sec. 5.4.
• Check the correct programming of the parameters and carry out any necessary cus-
tomization (compensation curve, power, temperatures, etc.).

4.3 Maintenance
Periodical check
To keep the unit working properly over time, it is necessary to have qualified personnel
make an annual check that includes the following tests:
• The control and safety devices (gas valve, flow meter, thermostats, etc.) must func-
tion correctly.
• The fume extraction circuit must be fully efficient.
• The airtight chamber must be sealed
• The air-fume end piece and ducts must be free of obstructions and leaks
• The condensate evacuation system must be efficient with no leakage or obstructions.
• The burner and exchanger must be clean and free of scale. When cleaning, do not
use chemical products or wire brushes.
• The electrode must be free of scale and properly positioned.
• The gas and water systems must be airtight.
• The water pressure in the cold water system must be about 1 bar; otherwise, bring
it to that value.
• The circulation pump must not be blocked.
• The expansion tank must be filled.
• The gas flow and pressure must correspond to that given in the respective tables.
The boiler casing, panel and aesthetic parts can be cleaned with a soft damp
A
cloth, possibly soaked in soapy water. Do not use any abrasive detergents and
solvents.
Opening the casing
To open the boiler casing (fig. 40):
1. Undo the screws (A)
2. Open, turning the casing (B)

Combustion analysis
Combustion can be analysed through the air sampling point (detail 2) and fume sam-
pling point (detail 1) shown in fig. 41.
To make the measurement, it is necessary to:
1. Open the air and fume sampling points
2. Insert the probes
3. Press the "+" and "-" buttons for 5 seconds to activate the TEST mode
4. Wait 10 minutes for the boiler to stabilise
5. Take the measurement
For natural gas the CO
2
For LPG the CO reading must be between 9.5 and 10%.

Analyses made with an unstabilised boiler can cause measurement errors.
