The Bio Flame 13-Inch Grate Kit Round Ethanol Fireplace Insert

Installation is tool-free and takes just minutes — simply measure your fireplace opening to confirm fit, clean out any ash or debris, then slide the grate kit into place where your logs used to sit. Because the unit is completely ventless, you can optionally seal your existing flue or chimney since no venting, gas lines, or electrical connections are required. The kit ships with everything you need to get started: a burner with grate, lighting rod, lighter, and funnel.

The Bio Flame 13-Inch Round Grate Kit has a heating capacity of 29,000 BTU (8.5 kW/h) and can heat an average of 1,054 sq. ft., which is noted to be roughly twice the output of most electric fireplaces. The unit produces natural-looking 12-inch flames, making it both a functional heater and a visual centerpiece.

The fuel tank capacity varies by retailer listing — some show 3.0 L (approx. 3.4 hours of burn time) while the manufacturer's own site lists a 5.0 L capacity version. As a general guideline, Bio Flame ethanol fireplaces average about 4 hours of burn time per liter of fuel, though actual burn time depends on the specific model and flame setting used.
