TEST mode activation
Press the
heating buttons
(details 3 and 4 - fig. 1) together for 5 seconds to activate the
TEST
mode. The boiler lights , gradually reaching the maximum heating power, set as
described in the following section.
The heating symbol (detail 13 - fig. 1) and DHW symbol (detail 9 - fig. 1) flash on the
display; the heating power will be displayed alongside.
fig. 39 - TEST mode (heating power = 100%)
To deactivate the TEST mode, repeat the activation sequence.
The TEST mode is automatically disabled in any case after 15 minutes.
Heating Capacity Adjustment (RANGE RATED)
A
This is a
“RANGE RATED”
boiler (according to EN 483) and can be adjusted
to the system's thermal requirement by setting the maximum heating capacity
for operation in 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 heat-
ing capacity (min. = 00 - max. = 100). See “Heating Capacity Adjustment” diagram
(fig. 40).
•
Press the
reset button
(detail 8 - fig. 1) within 5 seconds and the maximum heating
capacity will remain that just set. Exit TEST mode (see sec. 4.1).
After setting the required heating capacity, write the value on the sticker supplied and
place it under the data plate on the boiler. For subsequent checks and adjustments, refer
to the set value.

4.2 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. 5.3).
•
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 boil-
er.
•
Check correct connection of the electrical system and efficiency of the earthing sys-
tem
•
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
2
content in the fumes, with the boiler operating at max. and min. output, corre-
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. 5.3.
•
Check the correct programming of the parameters and carry out any necessary cus-
tomization (compensation curve, power, temperatures, etc.).
4.3 Maintenance
Periodical inspection
To ensure proper operation of the unit, it is necessary to have an annual inspection car-
ried out by qualified personnel, providing for the following:
•
heat exchanger check and cleaning with suitable products if dirty or clogged
•
check and possible cleaning of burner (do not use chemical products or wire brush-
es)
•
check and cleaning of electrodes, which must be free of deposits and properly po-
sitioned
•
seal and gasket check (burner, sealed chamber, etc.)
•
check and cleaning of sludge remover filters and system filters
•
check, cleaning and filling of condensate drain traps
•
check of wiring, contacts, electrical actuators
