Empire | White Mountain Hearth Keystone Premium B-Vent Gas Fireplace

The deep Premium 42-inch B-Vent fireplace offered by the company showcases their renowned Slope Glaze Burner, setting the industry standard for exceptional flame aesthetics. Within the burner, ceramic glazed pellets create a mesmerizing dance, swirling and tumbling the gas to produce a realistic flickering fire effect. Keystone fireplaces are accompanied by matte black slat louvers (excluding flush front models) and feature operable curtain screens.


The B-Vent fireplace design incorporates hem-bent seams, ensuring a superior seal while eliminating the need for numerous screws and fasteners. This innovative construction technique results in a lighter and more rigid enclosure, simplifying the installation process.
