6.3.2 No start-up
As stated if the combustion trigger is not detected a no ignition alarm is signalled, the display will
show the message "AT 5 NO START" and an acoustic signal will be heard at regular intervals (if
the buzzer function is active in Menu 6).
To disable the alarm, hold and press the ON-OFF (4) (about 2 seconds). The acoustic alarm will
stop and the boiler will first return to "FINAL CLEANING" status and then to "OFF."
Before starting a new ignition cycle verifying the cause of the alarm is required, specifically:
•
Check that the pellet tank is not empty.
•
Check that the brazier is in the right position.
Before attempting a new combustion remove the non-combusted pellet from the brazier.
CAUTION: An excessive quantity of pellets in the brazier, a humid pellet or dirty brazier
make the ignition stage difficult. If these critical conditions ar present a dense white smoke
capable of causing an explosion in the combustion chamber may form. The explosion can
be of such intensity as to break the glass of the dire door. Therefore pay attention to never
stay in front of the boiler during ignition stage if the fuel releases a dense smoke.
The boiler is however equipped with all safety systems required to minimise this risk.
If the device does not turn on regularly, the main cause may be insufficient maintenance or poor
pellet quality.
6.3.3 Normal Operation
As soon as the ignition phase is over, the boiler will go into normal working mode.
During this phase, the display will show the following information:
•
The first line shows the time.
•
On the second line to the right the temperature of the water in the boiler appears.
•
The third line shows the message "WORKING" with the set power (from 1 to 5) to the side.
•
The fourth line usually shows the instantaneous working power (flashing from 1 to 5). The
message "MODULATE" also is shown when water temperature reaches the set temperature (
see
corresponding paragraph
).
During normal working mode, the following operations can be performed:
•
Set Boiler power
choosing from one of the 5 available levels. Power setting is carried out via
BUTTONS "6" (to increase) and "5" (to decrease).
•
Set thermostat parameters
(
see corresponding section
).
•
Set the required boiler temperature between an interval from 60°C to 80°C.
The optimal
temperature for out boiler is 70°C,
we sincerely recommend leaving this setting except for
justified technical reasons.
Press "1" once and then set the temperature with button "1" to increase and "2" to decrease.
•
Display the water circuit pressure
. Accessing menu 1.
Periodic brazier cleaning is also active during working mode. Brazier cleaning mode is activated at
regular intervals of about one hour. In this way, the smoke extractor works at maximum power
while pellet feeding is reduced to minimum. For boilers with automatic cleaning of the flue gas pass
and/or of the brazier, also these functions are activated.
This operation is necessary for eliminating ash deposits inside the brazier and for ensuring proper
aeration and combustion. During brazier cleaning, the display will show the message "BRAZIER
CLEANING".
If you notice excessive accumulation of pellets in the brazier during normal operation, turn
off the boiler immediately and contact a support centre.
