Blaze King Sirocco 25


The Sirocco 25 is a medium sized fireplace insert. At 2.3 cu. ft., the firebox will take up to a 22″ log and can deliver warmth for up to 25 hours on low. The Sirocco 25 is very clean and efficient and can heat from 800 – 1,800 sq. ft. This flush insert extends to only 2.6 inches from the face of the fireplace to the door opening, helping to keep hearth protection to a minimum. The door features a large, 24″ x 11″, wide-screen glass viewing area with a nickel plated and hand made olive-wood door handle. Attention to detail is evident from the layered surround panel to the unique control system that allows you to select the heat you want.
