Black Glass Charcoal
- The Black Glass Charcoal is made from high-quality tempered glass and has been designed to withstand harsh weather and temperatures of up to 1300ºF/700ºC.


Indoor or outdoor multi-room application. With two open sides, view the flame from the front and the back.

Zero Clearance
- Self-contained, zero clearance construction allows your Flex fireplace to be framed into wood or metal studs, providing installation freedom and flexibility for builders.

Wind Screen

- Available in black, firebox comes with stainless steel burners and decorative Black Glass Charcoal.

Quick and Easy Assembly
- Requiring virtually no assembly, Flex Fireboxes are designed to be placed into the desired location, safely secured into position, and operated immediately.

Tested World Wide
- Our collection has been thoroughly tested against a number of global standards and is UL Listed in the USA, Certified for EU and UK in accordance with EN16647, and satisfies the ACCC Safety Mandate for Australia.

No Gas or Electricity
- No gas, no electricity, no chimney, no venting or external vent cap. 4 fewer General Contractors.

Rust Proof
- Zinc sealed steel construction powder coated with super hi-temp black paint prevents rusting so all fireplaces can be used both indoors and outdoors.

Clean Burning
- All the fuel is housed within Flex’s self-contained burner so you don’t have to run a gas line or electric wires through your walls. And because e-NRG Bioethanol is clean-burning, you don’t need a flue or a chimney.

Luxurious Finish
- Available in a timeless black finish, Flex Fireboxes come with stainless steel burners and black glass charcoal.
