Understanding Stack Temperature
An airtight arch gives you a critical advantage in efficiency and performance whether you are running a Forced Air Kit or if you choose to keep things simple with natural aspiration. The air-tight door and front will help prevent cold air from being pulled along the bottom of pan, negatively affecting evaporation rate and efficiency. Also, the airtight door keeps the operator safe from sparks and embers.
Competitor doors/fireboxes are often much too small. In contrast, the 16" x 16" Corsair doorway makes it easier to load wood, and generate more heat.
If you ever want to upgrade to Forced Draft — either now or in the future — you need an airtight door. With Corsair, you’re all set.
Regardless whether you have Forced Draft or Natural Draft, an airtight door increases efficiency. A leaky door works against you by allowing cold air to enter the firebox and cool your pans.
Our competitors’ cast iron door fronts have been cracking since the 1800s. The Smoky Lake Corsair door will not. We guarantee it.
All models of Smoky Lake Arches feature airtight doors.
