Product Description

Isokern Xcelux 48" overview

The 48" is the entry size of the Xcelux linear range, which scales up to 120". It suits primary suites, studies and smaller living rooms where you want the same clean, flush-burner appearance as the larger Xcelux fireboxes in a shorter span of wall.

As with the rest of the series, venting runs through the X-Ventiso mechanical system, sized from three fan options with adaptive controllers that hold proper draft. Dress the burner with one of five fireglass colors or with lava pebbles.
