Testing and commissioning

Boiler start-up must be preceded by testing, which includes an operational check of the following elements:
•
connection to the smoke evacuation system;
•
checking that all materials used to build the smoke duct, chimney and chimney pot are regulation and suitable for use.
The testing is positive only when all operational phases have been completed without any anomaly being detected.

Checks prior to start-up

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.
At first startup, remove all the components that could burn (instructions/label) from the boiler firebox.
Any lighting done after long idle periods requires the removal of any residual pellets that have remained inside the
hopper, in being damp fuel no longer suitable for combustion, and complete cleaning of the combustion chamber.

Loading pellets

Open the hopper cover and pour the pellet inside.
