The Langham Multiflue Remote Control inset gas fire is one of our most popular models thanks to its Slimline design. It is designed to fit virtually 99% of any modern pre-cast flues, pre-fabricated flue systems (class 1 or class 2 with min. 127mm or 5" diameter) or conventional chimneys. The Slimline firebox fits a standard opening, generally 406 wide x 558mm High (16" wide x 22"). Most importantly this fire only requires a fireplace depth of 108mm plus 20mm for debris collection. The maximum heat output is 3.1kW (Gross), which provides sufficient heat to warm a medium-sized room within a modern home. The Remote Control operates the output of the fire and can turn it down or off, a battery is required in the fire for ignition only. This fire is also available with a manual Rotary or Fingerslide control. It does not require a mains power supply.
