Frequently Asked Questions

  • No — the 24" Firebox SS is completely self-contained and requires no chimney, flue, gas lines, venting, or electricity, so no professional installer is needed. Because it is self-contained, it can be installed on an indoor or outdoor wall in a matter of minutes. An installation guide is included in the box for framing and fitting the firebox, which typically takes less than an hour.

  • The 24" Firebox SS delivers a maximum thermal output of 17,000 BTU (5.0 kW/h) and is rated to heat an average of approximately 742 square feet indoors. With a 2.5-liter fuel capacity, it can sustain that heat output for roughly 2.8 hours on a single fill of bio-ethanol fuel.

  • Yes — converting a standard wood-burning, gas, or electric fireplace to the Bio Flame 24" Firebox SS is straightforward and adaptable. If converting from gas, you simply cap the existing gas line and frame the firebox into the existing opening. No other permanent structural modifications are required.

  • The 24" Firebox SS includes a patented heat isolation chamber to protect surrounding structures, and it is constructed with 8mm tempered glass for added safety. Bio Flame is noted as the only ethanol fireplace manufacturer to have received UL (Underwriters Laboratories) and ULC (Underwriters Laboratories of Canada) certification, meaning the product has been tested by a third party against globally recognized safety standards.

  • The Bio Flame 24" Firebox SS comes with an industry-leading 5-year warranty that covers all operation-related functionality from the date of purchase. Items deemed unfixable under the warranty will be replaced with the same or a similar model. Note that the warranty does not cover damage resulting from improper handling, installation, or misuse.
