Product Description

Superior BRT4542 42" B-Vent overview

The BRT4542 is a natural-draft B-vent fireplace from Superior's Custom Series, venting vertically through standard 6" Type B gas vent that is easy to source. It suits homes with a straight path up through the roof and buyers who want a classic, radiant log fire.

A U-tube dual burner drives the flame through a multidimensional refractory concrete log set and a deep glowing ember bed, framed by herringbone refractory panels. It ships smooth-faced with hidden screen pockets and an easy-access flue damper with a safety shut-off switch. Choose millivolt (no electricity needed) or electronic ignition with battery backup. Superior is phasing this model out, so call before ordering.
