Frequently Asked Questions

  • No professional installation or chimney is required. The SEK XL is a freestanding, ventless fireplace that needs no chimney, flue, gas lines, or electrical connections — simply pour the bio-ethanol fuel and light it. It can also optionally be built into a dividing wall to serve as a see-through fireplace between two rooms.

  • The Bio Flame SEK XL delivers 27,000 BTUs and is capable of heating areas averaging up to 1,001 square feet, making it well-suited for large living rooms or open-plan commercial spaces. Because it is ventless, 100% of the heat generated stays in the room with no loss through a flue or chimney.

  • The SEK XL features a generous 11-liter fuel tank that provides up to 11 hours of continuous burn time on a single fill. The flame intensity can be adjusted at any time, and the fireplace can be extinguished by closing the damper door using the included lighting wand.

  • The Bio Flame SEK XL comes with a 5-year parts and labor warranty, which begins on the date of purchase and covers all operation-related functions. The warranty does not cover damage from improper handling, installation, misuse, chips, scratches, or glass breaks, and items deemed unfixable will be replaced with the same or a similar model.

  • Yes, the SEK XL is safe for both indoor and outdoor use. It is constructed from 304-grade stainless steel with a brushed stainless steel interior and 8mm tempered glass on both sides for added safety and durability. Bio Flame is the only ethanol fireplace manufacturer to have received UL (Underwriters Laboratories) and ULC certification, confirming the fireplace meets rigorous third-party safety standards.
