Who It’s For

What Makes It Special

Blaze King designed the Sirocco 25 and Ashford 25 to give a very large glass viewing area while still fitting inside a small fireplace, with a nickel-plated and hardwood door handle.

A dual variable-speed fan is standard. Every Blaze King has a built-in thermostat that needs no electricity: it adjusts the combustion air automatically, and with the catalytic combustor lets you turn the heat down by up to 70% between high and low. Blaze King says its inserts can burn up to 33% less wood.

Possible Downsides
