This removable cap is designed to provide additional safety and to give your Iron Ember Chiminea a completed look. The hood of your chimney will catch much of the smoke and sparks and guide it up through the flue. As this leaves the chimney, the sparks will be disrupted by the cap. The Chimney Cap also keeps the rain from entering the fireplace. The roof covers the rest of the firebox, so with the Cap you have full coverage from the top for all-weather use. The cap is built from 1/4” plate and 1/2” steel rods, and is coated with our signature high heat paint.
