A Fireline Inset stove is designed to fit neatly into a wall. The Fireline FPi5W Inset for example, is designed to fit perfectly into a 20-inch fireplace opening. The firebox technology is well adapted to fit this space thereby maintaining 78% efficiency.
The 16-inch and 22-inch FPi5 has been designed to fit virtually any standard Class 1 chimney. There are three models in the range, a 5kW version, a 5kW Wide version, and an 8kW version for those who need a little more heat.
