WOOD COMBUSTION BASICS
Figure 23, above, shows the process by which dry seasoned wood is turned into heat in the
Ovation stove. The following information provides some wood combustion basics. An
understanding of this process will ensure a lifetime of satisfaction from your Ovation product.
Proper care and maintenance will ensure that the Ovation stove requires minimal maintenance
while providing maximum heating comfort for your environment. For specific product or
combustion questions, contact your local authorized Heritage stove dealer.
In a normal wood combustion process as heat is added to start a fire, water is first boiled out of
the wood. As moisture is dried from the wood, volatile matter and fixed carbon matter are
released and available to be burned to create heat. Any remaining product left behind in the burn
process is defined as ash. FIGURE 24 illustrates the combustion process of wood.
