The Blenheim Flueless inset gas fire is based upon a traditional inset gas fire but due to its innovative catalytic Flueless technology doesn't require a chimney or flue. It features¿all the benefits of Flueless catalytic technology; 100% efficiency, reduced running costs, simple installation, realistic coal fuel bed and an ultra clean burning ribbon burner. Being Flueless all the of the 2.3kW heat output is distributed into the room with no loss up the chimney unlike a conventional gas fire. A 43mm spacer frame is fitted as standard to minimise fitting depth (92mm + 20mm clearance). The only considerations when installing this appliance are a minimum room size of 27m¿, an accessible 8mm gas supply and 100cm¿ purpose provided ventilation. There is no requirement for mains power supply or battery for ignition.
