About the Dauntless

The Dauntless FlexBurn — a mid-size top-loading catalytic wood stove with a cast iron griddle top, swing-out ash pan and thermostatic combustion, in four finishes.

Fearless and resolute, this timeless beauty delivers steady overnight heat even on the fiercest of winter nights. Unwavering and steadfast, yet flexible. A cast-iron griddle top and optional cooking grill help you connect around food and flame all year long. Load wood from the top to maximize firebox capacity while keeping smoke and embers contained, remove ashes cleanly even while the stove is hot with the swing-out ash pan, and enjoy longer, more even heat from thermostatically controlled combustion with the included catalyst. Sized for small and mid-size rooms.
