The Blenheim Fingerslide High Efficiency glass fronted inset gas fire is designed to fit multiple flue installations. It is compatible with most pre-cast flues, pre-fabricated flue systems (class 1 or class 2 with min. 127mm / 5" diameter or greater) and conventional class 1 brick built chimneys. The multi-flue firebox fits a standard fireplace opening, typically 406 wide x 558mm High (16" wide x 22") and requires a minimum fireplace depth of only 125mm, plus 20mm for debris collection. The High efficiency engine reinvents the traditional flued inset coal-effect gas fire. The discrete glass front helps increase performance by reducing the amount of heat input required while the patented safety draft diverter system increases safety in the event of a flue draft reversal. This model used Fingerslide control to make using the fire easier to operate as they control is located in the top right corner of the fire, it is also available as a manual rotary control fire.
