The apparatus processes the smoke and pollutants thru the firebox then thru a flue and into the new novel innovative patent pending invention which emits no smoke into the air and then returns thru a closed loop back to the firebox. No smoke, pollutants or carbons are ever emitted into the atmosphere.
The Environmental Protection Department of the government states that because NO emissions are emitted into the atmosphere then NO air control permits will be required by the government. This is a big deal.!!!
