Technical parameters

Attention!

 - Do not use without radiators and/or convectors installed. Burning wood in the stove with an empty back boiler will cause it to crack.

 - Reaching the desired output depends on:

• The chosen fuel with the required calorific value and moisture content
• The subsequent lighting and fuel loading
• The regulation of the primary and secondary air
• The regulation of the chimney draught
• The effective air exchange, etc.

 Recommendations

- We recommend that the central heating system be of the open type. All parts of the system must be protected from freezing. For systems with forced circulation, it is advisable to fit a UPS to the circulation pump.

 - If there are copper elements in any part of the system, it must be protected from electrolysis by adding a magnesium anode or a similar type of protection.
