BOILER USE

Introduction

The pellet boiler has the advantage of combining the heat generated by the combustion of wood with the convenience of automatic
water temperature management and the possibility of weekly programming of switching on/off, as well as the connection of a
thermostat and/or chronothermostat and start-stop remote control.
For safe and reliable use:
- when lighting and using the unit the first time, unpleasant odours may be created, therefore air the room thoroughly;
- the hopper must only be filled with good quality pellets; make sure the bag does not come into contact with the hot surfaces
of the boiler;
- do not put any fuel other than the prescribed pellets in the hopper;
- the unit must not be used as a waste incinerator;
- the boiler must only operate with the fire door always closed.
- the fire and ash door seals must be checked periodically to prevent air from entering;
- to ensure thermal efficiency and correct operation it is necessary to clean the brazier every time pellets are loaded;
- when lighting the boiler for the first time, allow it to heat up gradually by setting low operating temperatures (see the section
on temperature setting);
- during lighting, operation and shutdown, the boiler may creak a little due to the heat expansion.
