How does burning work with the Pyroclassic IV?

Solid wood must change to gas and vapour before any burning can take place. This change occurs by heating wood to high temperatures to make the best gas fuel, low temperatures will make smoke and tars that are simply unburnt fuel. The Pyroclassic® IV is a North/South burning fire so the fire is started in the front of the fire chamber and continues along the length of the wood to the rear. To make the best use of your firewood please ensure logs are placed lengthways into the fire chamber – NOT sideways. Your objective is to achieve a high temperature in the fire chamber quickly, which is easy using the Turboslide and dry wood. You will never get the fire to burn correctly if you try starting fires with green or wet wood. The only fuel authorised for use with this appliance within Urban Clean Air Sheds and Smoke Control Zones is well seasoned wood with a moisture content of 25% or less on wet weight basis, 12-18% is ideal.
