STAGES FOR THE FIRST START-UP TEST

• Make sure you have read and fully understood the contents of this instructions manual.

• Remove all components that could burn from the closed replace rebox and door (instructions and various adhesive labels).

• Remove the stickers from the ceramic glass otherwise the high temperature could melt them and cause irreparable damage to the

glass. In this case the manufacturer will not guarantee the glass.

• Open the front combustion air damper completely using the hook supplied.

• Position small sized and thoroughly dry wood (moisture 15/20%). Light the re on moderate power without heating the structure

excessively. Any smells from processing and/or evaporation residues will be emitted the rst few times the replace is lit and will

disappear after it has been used a few times on full power.

• Do not close the sliding door immediately, but leave it open by about 10 cm so that the wood can burn better and so that any internal

moisture can dry out. When the ame is stable close the door completely.

One can use wood for heating such as oak-beech-ash-robinia-durmast wood or uncoated pressed wood logs. The latter have a high

caloric value and must be used with caution to avoid overheating that could damage the product.Fuels such as poplar-pine-

linden-chestnut have a low caloric value as the wood is soft. The humidity content is fundamental for all types of wood.
