Activating TEST mode
Press the heating buttons
(details 3 and 4 - ) at the same time for 5fig. 1seconds to activate TEST
mode
.
The boiler lights at the maximum heating power set as described in the following section.
The heating symbol (detail 14 - fig. 1) and DHW symbol (detail 8 - fig. 1) flash on the display; the heating power will be
displayed alongside.
fig. 28 - TEST mode (heating power = 100%)
To deactivate TEST mode, repeat the activation sequence.
In any case, the TEST mode is disabled automatically after 15 minutes.
Heating power adjustment
To adjust the heating power, switch the boiler to TEST mode (see sec. 3.1). Press the heating buttons
(de-
tails 3 and 4 - fig. 1) to increase or decrease the power (min. = 00 - max. = 100). Press the RESET button
within 5
seconds; the max. power will remain that just set. Exit TEST mode (see sec. 3.1).
3.2 Start-up
B
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. 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.
•
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
2
content in the fumes, with the
boiler operating at max. and min. output, corresponds 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. 4.4.
•
Check the correct programming of the parameters and carry out any necessary customization (compensation curve,
power, temperatures, etc.).
