Keystone B-Vent Fireplaces combine modern technology with traditional venting to create the appearance and performance of a conventional fireplace but with the convenience of gas.

Empire B-Vent systems let you prolong the flicker of the flames without overheating your room.  The BVD-34 input is 21,000 Btu; the BVD-36 is 25,000 Btu; and the Premium BVP-42 is 30,000 Btu.

The hand-painted ceramic fiber Log Set features large logs, arranged to fill the fireplace and complement the flames.

    Keystone Premium Fireplace (BVP42FP)

    Empire deep Premium 42-inch B-Vent fireplace features our Slope Glaze Burner – the industry standard for great looking flames.  Ceramic glazed pellets in the burner tumble and swirl the gas to produce a natural flickering fire.

    Keystone fireplaces come with matte black slat louvers (except flush front models), and operable curtain screens.

    Empire B-Vent fireplace features hem-bent seams that provide a better seal while eliminating dozens of screws and fasteners.  The result is a lighter, more rigid box that’s easier to install.

    FBB4 automatic Blower with variable speed control may be used on Louvered models.

    *Please Note: For Propane models require the purchase of a natural gas to propane conversion kit. Please check Options & Accessories section for more details.
