Frequently Asked Questions

  • The Bio Flame 13-Inch Ethanol Burner Grate Kit is designed to convert virtually any existing fireplace type — wood-burning, electric, or gas — into an ethanol fireplace in just minutes. It can also be used as a standalone tabletop fire feature on any level surface, since the burner is enclosed in an insulated bottom tray that protects the surface beneath it. The kit is suited for both indoor and outdoor use in homes, condos, restaurants, hotels, and offices.

  • The Bio Flame 13-Inch Ethanol Burner delivers approximately 12,000 BTUs of heat output and can heat an average of 430 square feet, making it an efficient zone-heating solution. Bio Flame's ethanol fireplaces overall can generate between 3.5 kW/h and 15.8 kW/h depending on the model and size. This makes the 13-inch unit well-suited for supplemental heating in small to medium-sized rooms, apartments, or patios.

  • No professional installation is required — the kit is entirely plug-and-play with no gas lines, electrical connections, chimney, or flue needed. To install, you simply measure your fireplace opening to confirm fit, clear out any debris, then unpack the grate kit and place it inside the existing fireplace. Because the system is completely ventless, you can optionally seal the old flue, and you're ready to use your new ethanol fireplace in a matter of minutes.

  • The kit comes complete with a fireplace grate, ethanol burner, lighting rod, lighter, funnel, and a user's manual — everything needed to complete the conversion. The average burn time is approximately 4 hours per liter of fuel, though this can vary depending on the flame setting and environment. Bio Flame also notes that their ethanol burners are 20–30% more fuel-efficient than competing burner models.

  • The Bio Flame 13-Inch Ethanol Burner Grate Kit is backed by an industry-leading 5-year warranty covering all operation-related functions, beginning from the date of purchase. The warranty does not cover damage that occurred during shipping, improper handling or installation, or cosmetic issues such as chips, scratches, or glass breaks. Items deemed unfixable under the warranty will be replaced with the same or a similar model, and a dated receipt is required to apply the warranty.
