Ignition and normal operation

Before igniting the boiler:
• Check that the furnace door is locked.
• Make sure that the pellet tank is full or contains enough pellet so that the boiler shall function for
the desired amount of time.
• Make sure that the brazier is clean, free of ashes, combustion residue or unburned pellets. If
necessary, remove the brazier and thoroughly clean it, then replace it with care in its housing).
• In the event of start-up with the programmable thermostat, make sure that the brazier is in the
indicated conditions after last use.
When the boiler is connected to the electrical system but not in work mode, the display will show
the message "OFF
6.3.1 Boiler start-up
To start the boiler, press and hold the start button (4) for 2 seconds.
If you start the boiler during the final cleaning phase, the display may show the message "WAIT
COOLING." In this case, wait a minute before retrying ignition.
First phase. Preparation
The message "START" will appear on the display. In this phase, which lasts for about one minute,
the pellet glow plug activates and combustion chamber forced ventilation starts along with
activation of the fume extraction fan.
Second phase. Ignition
After the preparation phase, the display will show the message "LOAD PELLETS" and ignition will
begin. This second phase is divided into two parts: pre-loading and actual ignition. First, the pellet
feed screw is activated (the Feed screw ON LED
depending on the model, and pellets begin to fall inside the brazier.
Remember that the brazier must be perfectly clean at this beginning of this stage.
Once this pre-loading is completed, the pellet feed screw will stop for a variable amount of time
depending on the model (for two to three minutes). After this waiting phase, the pellet feed screw
will start to switch on at regular intervals and pellets will then continue falling inside the boiler
brazier, while the glow plug and then fume exhaust fan will both remain activated.
As soon as the pellet covers the ignition glow plug hole you will initially notice the brazier redden
and then a small flame ignite.
If the pellet continues to fill the brazier without this happening, you can manually interrupt the
ignition process without waiting for the "AL 5 NO IGNIT" alarm to affect the boiler.
This second stage is completed when the boiler detects successful ignition of the combustion
process, or rather after 4-5 minutes from the ignition of the first flame.
If combustion is not detected within a certain amount of time the no ignition alarm is triggered
(message "AT 5 NO IGNIT").
Third phase. Stabilisation
Once combustion triggering has been detected, the third phase will start and the display will show
the message "FIRE PRESENT". Pellet feeding is reduced and ventilation increased in order to
allow a stabilisation of the flame and disposal of excess pellets accumulated in the brazier during
the ignition phase. This phase lasts about 5 minutes.
Once the stabilisation phase has been completed ("FIRE PRESENT"), the boiler passes to the
normal working phase.
