13” Round Ethanol Fireplace Burner, Indoor/Outdoor

No, the Bio Flame 13-inch Round Ethanol Fireplace Burner is completely vent-free and requires no gas lines or electrical connections — making installation straightforward in virtually any location. Because ethanol only emits heat, water vapor, and a minimal amount of carbon dioxide, no chimney or flue is needed. You simply place it on a flat, non-combustible surface, fill it with bioethanol fuel, and light it with the included lighting rod.

The 13-inch Round Ethanol Burner (5.0L model) delivers approximately 29,000 BTU (8.5 kW/h) and is rated to heat on average up to 1,054 square feet indoors. The smaller 2.0L version of the 13-inch burner outputs around 12,000 BTU (3.5 kW/h), heating approximately 430 square feet. Output and effective range will vary based on room layout, insulation, and whether the burner is used indoors or outdoors.

Burn time depends on the fuel capacity of the model you choose: the 2.0L version burns for approximately 1.5–2 hours per fill, while the larger 5.0L Round Burner offers significantly longer sessions. As a general guideline, the average burn time across Bio Flame ethanol burners is about 4 hours per liter of fuel, though this varies by model size and environmental conditions such as wind or room airflow.

The Bio Flame 13-inch Round Ethanol Burner comes with a 5-year parts and labor warranty, which the brand describes as the best in the market. The warranty begins on the date of purchase and covers factory service repair of parts found to be defective; items deemed unrepairable will be replaced with the same or a similar model. Note that installation costs are not reimbursed under the warranty terms.

No — according to Q&A responses from authorized dealers, the 13-inch Round Ethanol Fireplace Burner is not approved for use with decorative rocks, fire glass, or similar media placed around or over the burner. The burner is constructed entirely of 304-grade stainless steel and must be kept clear of non-approved materials to maintain safe operation and preserve the product warranty. For styling, you can surround the burner with a custom non-combustible firebox or surround, but no media should contact or cover the burner unit itself.
