"Kuuma" principle - the logs burn from the front to
the back. Primary air ignites only the amount of wood that will combust
with the available oxygen within the fire chamber. Electronic control
precisely regulates the amount of preheated air admitted into the fire
chamber. Because the gases and volatile liquids burn at approximately
1000 degrees Fahrenheit it is important that the secondary air is
preheated before it is introduced into the secondary zone. The fire
burns with a nice soft low flame resulting in a highly efficient burn for a long period of time. You don't need a raging fire to produce a clean burn and useful heat.
