No chimney! No gas! No smoke! This fireplace uses bio-ethanol fuel to provide refined warmth and bring the joy of a real flame into your living space. Bio-ethanol burns clean and it is non-toxic. It releases small amounts of carbon dioxide and water vapor, similar to a candle. This fireplace can be hung on almost any wall including plaster walls, stone walls, concrete walls or wood walls. The Diamond is made of a high quality powder coated steel with integrated heat resistant insolation, a hanging system that is earthquake resistant and lastly, allows for an optional front tempered glass for a greater sense of security. Diamond I is equipped with three cast iron burners which will offer three individual flames. You can choose to light all three, two or one.
