Empire Comfort Systems Elite Radiant Vented Burner, 18-in., Millivolt

At 33,000 BTU and 18 inches, the Empire Comfort Systems Elite Radiant Vented Burner (BFL18MTN) is built around a millivolt standing pilot system with match-light ignition — a setup that earns its keep precisely because it asks nothing of your home's electrical system. No power outage is going to interrupt a fire that runs on its own pilot logic.

The burner is UL-certified and operates on either natural gas or propane, making it a flexible choice whether your home runs on a utility line or a tank. The Elite Radiant Vented burner type is engineered to work within a vented fireplace system, drawing combustion air from the room and exhausting it through a proper flue — the right architecture for genuine radiant heat and authentic flame character.

Minimum firebox requirements are 20 inches wide by 16 inches deep, and the 5/8-inch grate size ensures compatibility is straightforward to verify before you buy. No guesswork, no surprises on installation day.

For log sets, Empire has done the compatibility work for you: the Kensington Forest Ceramic Fiber Log Set (LKF18) and the Pioneer Refractory Vented Log Set are both confirmed matches. Ceramic fiber and refractory log sets each have their own look and heat-retention characteristics, so the choice between them comes down to your aesthetic preference and how the set interacts with your firebox interior.

If match-light ignition isn't quite what your project calls for, this same 18-inch Elite Radiant platform is available in three alternative ignition configurations: the BFM18MTN with a Manual Safety Pilot, the BFR18MTN with a Millivolt valve and On/Off Switch, and the BFE18MTN with an Intermittent Pilot and Variable Remote Control. Each shares the same core burner hardware, so you're choosing ignition convenience, not a different burner.

The BFL18MTN is priced at $789.00 and arrives UL-certified — a detail worth noting if your installation requires documented compliance. For a vented gas burner that keeps its specifications honest and its operation simple, this is a well-defined product doing exactly what it promises.
