Heating power adjustment
To adjust the heating power, set the boiler on TEST operation (see sec. 3.1). Press the heating buttons
(part
3 and 4 - fig. 1) to increase or decrease the power (minimum = 00 - Maximum = 100). Press the RESET button
within 5 seconds and the maximum power will remain as has just been set. Exit TEST operation (see sec. 3.1).
Ignition power adjustment
To adjust the ignition power, set the boiler on TEST operation (see sec. 3.1). Press the tap water buttons
(part 1 and 2 - fig. 1) to increase or decrease the power (minimum = 00 - Maximum = 60). Press the button
within
5 seconds and the ignition power will remain as has just been set. Exit TEST operation (see sec. 3.1).
3.2 System start-up
B
Checks to be made at first ignition, and after all maintenance operations that involved disconnecting from the
systems or an intervention 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 the correct preloading of the expansion tank (ref. sec. 4.4)
•
Fill the water system and make sure that 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.
•
Make sure there are no water leaks in the system, hot water circuits, connections or boiler.
•
Check the correct connection of the electric system and the functioning of the earth system. l
•
Check that the gas pressure value for heating is as required.
•
Make sure there are no flammable liquids or materials in the immediate vicinity of the boiler
Checks during operation
•
Ignite the appliance as described in sec. 1.3.
•
Check the airtightness of the fuel circuit and water systems.
•
Check the efficiency of the flue and air-fume ducts while the boiler is working.
•
Check that the water is circulating properly between the boiler and the systems.
•
Make sure that the gas valve modulates correctly in both the heating and hot water production phases.
•
Check the proper ignition of the boiler by performing various tests, turning it on and off with the room thermostat or
remote control.
•
Make sure that the fuel consumption indicated on the meter corresponds to that given in the technical data table in
sec. 4.4.
•
Make sure that with no call for heating the burner correctly ignites on opening a hot water tap. Check that during
heating operation, on opening a hot water tap, the heating circulator stops and there is a regular production of hot
water.
•
Check the parameters are programmed correctly and perform any required customization (compensation curve,
power, temperatures, etc.)
