ENERGA 70-55 TUNNEL
9 FUELS
9.1 WOOD
Suitable fuels are:
• All sorts of clean wood (forested). The wood must have been dried for at least two
years. Well-dried wood has a humidity percentage between 10 and 20%.
Recommended dimensions: • Energa 70-55 Tunnel: length: c. 26 cm
outline: c. 30 cm
• Compressed wood blocks without binder (see wood dimensions).
• Hard woods burn slowly and easily form charcoal; for example hornbeam, oak, ash,
beech, elm and birch.
Softwood burns with more fl ame, but forms less charcoal and radiates less heat.
Examples are spruce, pine, poplar and linden.
Unsuitable fuels are:
• Painted, bonded (chipboard, MDF etc.) or impregnated wood, plastic and other
fl ammable waste. Stoking a fi re with this is completely forbidden. The combustion
gases released by these materials are aggressive and will attack your fi replace insert
and the environment.
• Paraffi n-containing open fi re lighters are not suitable for a closed fi re. A closed fi re
generates more heat than an open fi re, thus the paraffi n will melt out of the blocks
prematurely.
• Damp wood burns poorly, is unsuitable and produces too much smoke (including in
the room when you are topping up the wood), dirties the glass, leaves deposits in the
chimney and delivers about half the heat output of dried wood.
Do not burn coal in the built-in fi re. The fi re is not designed for this.
