Dear Customer,
Our boilers are designed and built in compliance with the European standard EN 303-5 (manual or automatic loading solid fuel
boilers). They also meet the essential requirements of directive 2006/95/EC (Low Voltage) and directive 2004/108/EC (Electromagnetic
Compatibility).
To get the best performance out of your boiler, we suggest you read the instructions in this manual carefully before
starting it up for the rst time.
This installation and use manual forms an integral part of the product: ensure that the manual is always supplied with the device, even if
the boiler changes owner. If the manual is lost, you can request another copy from the local technical service or download it directly from
the company website.
All local regulations, including those regarding national and European regulations, must be respected when the device is installed.
In Italy, for the installation of devices with biomass lower than 35KW, refer to ministerial decree 37/08, and the qualied installation
technician with the appropriate requisites must issue a certicate of compliance for the system installed.

parts could be hazardous for the operator’s safety and relieves the company
from any civil and criminal liability.
• Many of the surfaces of the product get very hot (door, handle, glass, smoke
extraction pipes, etc.). Avoid coming into contact with these parts
without adequate protective clothing or suitable means, such as
gloves with thermal protection or“cold handle”operating systems.
• It is forbidden to operate the product with the door open or the glass
broken.
• The doors/covers on the appliance must remain closed when it is not
used.
• The product must be powered by an electrical system that is equipped with an
eective earthing device.
• Switch the product o in the event of a fault or malfunction.
• Accumulated unburned pellets in the burner after each “failed start-up” must
be removed before lighting again. Check that the burner is clean and positioned
properly before lighting again.
• Shut the stove down in the event of a breakdown or bad running and
contact the engineer immediately.
• Pellets must not be fed manually into the burner – this wrong
behaviour can generate an abnormal amount of unburned gas, with a
risk of explosion in the chamber.
• Accumulated unburnt pellets in the burner after a failed ignitions
must be removed before lighting.
• Failure too clean and maintain the brazier can result in improper running and
explosions within the stove. Make sure you remove and clear the holes in the
brazier and any loose encrustations every time you empty the ash from the
stove or every time you have a failed ignition.Make sure that the holes in the
brazier are never reduced in size as this will aect the safe performance of the
stove if not maintained.
• Do not wash the product with water. The water could get inside the unit and
damage the electrical insulation and cause electric shocks.
