TEST mode activation
Press the heating buttons (details fig. 13 and 4 - ) together for 5 seconds to activate the TEST mode. The boiler lights
at the maximum heating power set as described in the following section.
The heating symbol (detail 24 - fig. 1) and DHW symbol (detail 12 - fig. 1) flash on the display; the heating power and
actual flame current value (uA x 10) will be displayed alongside.
Press the heating buttons (details 3 and 4 - fig. 1) to increase or decrease the power (min.=0%, max.=100%).
Press the DHW button "-" (detail 1 - fig. 1) and boiler power is immediately adjusted to min. (0%). Press the DHW button
"+" (detail 2 - fig. 1) and boiler power is immediately adjusted to max. (100%).
If the TEST mode is activated and enough hot water is drawn to activate the DHW mode, the boiler remains in TEST
mode but the 3-way valve goes to DHW.
To deactivate the TEST mode, repeat the activation sequence.
The TEST mode is automatically disabled in any case after 15 minutes or on stopping of hot water drawing (in case of
drawing of hot water enough to activate DHW mode).
Heating power adjustment
To adjust the heating power, switch the boiler to TEST mode (see sec. 3.1). Press the heating buttons (details 3 and 4
- fig. 1) to increase or decrease the power (min. = 00 - max. = 100). Press the RESET button within 5 seconds and the
max. power will remain that just set. Exit TEST mode (see sec. 3.1).
3.2 Starting
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. 4.4).
•
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. 1.3.
•
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.
