A choice of three generous widths make the Gigafocus a truly exceptional model. A union of design that allows this fireplace to expose its flames red-handed in their unbridled optimism. In this model, a choice of three generous widths combines with the security of a telescopic glass door. The heat-resistant glass door comes in three widths (1.50, 1.70 and 1.90 m) and one height (0.40 m). The door can swing open to a 45° angle. The fresh-air inlet (ø 160 mm) is an airtight duct. The interior of the hearth and the frame are highly heat-resistant matt-black steel. Upper and lower air vents necessary. Guaranteed efficiency with a minimum flue length (interior plus exterior) of 5 m.
