2:   Secondary Combustion Chamber Doors
Wide insulated door providing access to the secondary combustion chamber for cleaning.

3:   Primary Burn Chamber & Air Panels
Large sealed firebox chamber allowing wood to burn only when air is introduced with specially designed panels to distribute preheated air, evenly within the firebox.

4:   Gasification Manifold
A uniquely designed, high temperature poured refractory unit, that injects preheated air directly at the combustion zone.

5:   Secondary Combustion Chamber
Exhaust gases from the firebox are injected with air to achieve temperatures up to 2,100°F and 99% fuel combustion.

6:   Heat Exchanger Tubes & Heat Exchanger Cleaners
Strategically placed in the water reservoir to transfer heat to the water, assisting in achieving high efficiency and low emissions. Each tube is a equipped with a turbulator which removes any build up of fly ash.

7:   Insulated Heat Exchanger Doors
Large insulated door for easy cleaning of heat transfer tubes.

8:   Stainless Steel Flue
Compared to conventional flue exhausts which have temperatures between 800°F - 1000°F, the Pristine Series have a flue exhaust as low as 300°F.
