Check before lighting
Before lighting the boiler:
•
make sure to have read and understood the information given in the manual;
•
follow the oral instructions on operation of the unit provided by the installer prior to use.
•
the hopper must be filled with pellets;
•
the combustion chamber must be clean;
•
the brazier must be completely free, cleaned of any combustion residuals and correctly fitted in the brazier holder;
•
check hermetic closing of the ash box and fire door;
•
check the connection of the power cable and switching to ON/1 of the switch located on the back of the boiler.
•
check opening of the delivery and return shutoff valves as well as the water circuit pressure.
Before switching on the boiler it is important to check that the turbolator shaker device is at rest or in the lower position. An incorrect
⚠
position of the turbolators leads to malfunctions and an excessive formation of dust and unburnt parts.
At first startup, remove all the components that could burn (instructions/label) from the boiler firebox.
The use of pellets with different characteristics to those tested by the technician during the first start-up implies a new calibration of
⚠
the boiler pellet load parameters; this intervention is excluded from the warranty.
Any lighting done after long idle periods requires the removal of any residual pellets that have remained inside the hopper
and complete cleaning of the combustion chamber.
Auger loading
Before starting the boiler for the first time, whenever the boiler is in alarm "06 - Pellets finished", and in any case whenever the hopper
has emptied completely, the initial feed screw loading is required. This phase serves to fill the pellet loading system so that, at the
time of ignition, the correct pellet loading takes place in the brazier. In the event that the feed screw operations are not carried out,
⚠
there may be boiler ignition failures.
It is not necessary to remove the pellets in the brazier: the pellets loaded are sufficient for subsequent ignition.
Switching on and startup stage
To light the boiler, press the button 'P4' for 3 seconds: the message 'START' will appear on the display.
This stage is automatic and managed entirely by the electronic controller without the possibility of changing the parameters.
Alternatively the boiler can be lit by pressing the buttons P4 and P5 together for 3 seconds. The message AWAITING REQUEST
appears on the display. With this mode the boiler switches to standby status and carries out the lighting-start stage only if a request
for heat is recognised, e.g. to heat the water or for DHW (if available).
The boiler carries out the startup stages in sequence according to the following table:
Status
OFF
START - PREHEAT
PELLET PRELOAD
AWAITING FLAME
PELLET LOADING
⚠
FIRE PRESENT
Do not use flammable liquids to light the unit.
Failed ignition
If the system does not detect the ignition of the flame within the preset time, operation will be blocked with the "No ignition" alarm.
Before relighting the boiler, check that there are pellets in the hopper, that the door and ash drawer compartment are closed, that
there are no obstructions to the combustion air inlet system. If the problem persists, it could be due to a technical problem (ignition
plug, adjustments, etc ...), so please contact a Ravelli CAT.
��
È sufficiente resettare l'allarme e riaccendere la stufa: prima di caricare ulteriore pellet, la stufa cercherà di accendere
⚠
l'eventuale pellet già presente nel braciere.
In case of persistent failed lighting, contact the Service Centre.
