Empire Comfort Systems Elite Radiant Vented Burner, 21/24-in., 55,000 BTU

At 55,000 BTU, the Empire Comfort Systems Elite Radiant Vented Burner (BFL2124MTN) is a serious piece of hardware designed to bring real, radiant heat to an existing solid-fuel fireplace — no gut renovation required. The 21/24-inch burner slips into fireplaces with a minimum rear width of 22 inches, front width of 26 inches, and a height of at least 20 inches, making it a practical fit for a wide range of traditional masonry and prefabricated fireplaces.

Ignition is match-light, which is exactly what it sounds like: no electronic components to troubleshoot, no wall switches to hunt for. Strike a match, open the gas, and you have fire. There's an elegance to that simplicity, and it's one fewer thing to worry about on a cold evening.

Installation is straightforward for a qualified technician. The burner is designed specifically for vented installations in fireplaces originally built for solid fuel — meaning the damper stays open during operation. A damper clamp is included to ensure the damper remains in the correct position, so the system operates safely and as intended. Minimum venting requirement is 49 square inches, and the gas inlet pressure range runs from 7.0 to 10.5 inches of water column, with a 3.20 mm orifice sized for natural gas.

This burner is UL Certified, which matters both for peace of mind and for satisfying local inspection requirements. Compatibility is confirmed with the Pioneer Refractory Log Set (24/30-in., 11-piece, model LPR2430) and the Kensington Forest Ceramic Fiber Log Set (24/30-in., 12-piece) — log sets are required for operation and sold separately. A valve kit is also available separately, and for those who may need flexibility down the road, a Liquid Propane conversion kit (CKV115) is available as a separate purchase.

If your existing fireplace has been sitting idle since the last cord of wood ran out, the BFL2124MTN offers a clean, capable path back to a working hearth — without replacing the fireplace itself.
