Wisconsin Outdoor - Model 7200E - Pristine Gasification Series -Crown Royal Stoves

For the Pristine Gasification Series outdoor wood furnaces to achieve a 99% combustion efficiency we had to take a new approach to air flow. Instead of “pushing” the air from the top, we decided to “pull” the air from the bottom, creating a Negative Pressure Gasification System. When the outdoor wood furnace is completely sealed, the air is “pulled” downward, forcing all gasses from the Firebox through the ash bed into the Secondary Combustion Chamber. This makes the system virtually smokeless, with lower exhaust temperatures at the chimney, and allows wood placement to be more forgiving.
