Overview:
- The Flex 86SS is the first size in the Flex range wide enough to need two burners for its full-width All Flame configuration, a 2390mm opening built for a genuine architectural centrepiece rather than a single-room feature.
-
Design & Build:
- Zinc-sealed mild steel surround and toughened glass, built around twin Grade 304 stainless XL900 burners in All Flame form (30,000 BTU/h combined from an 18-litre tank), or a single larger XL1200 (Log Box Left/Right) or XL900 (Log Boxes Both Sides) as the log storage narrows the flame width. The burner is available in Stainless Steel as standard, or a Black ceramic-coated finish for a flat, monochrome look, at a fixed premium.
-
What it does well:
- All Flame runs 8 to 13 hours per fill and is rated for a 220m³ room, nearly double the coverage of the single-burner 68SS All Flame. Even its most reduced configuration, log boxes on both sides, still runs a single XL900 burner at 15,000 BTU/h, real heat output rather than a token flame.
-
Trade-off worth knowing:
- At 2390mm and up to 122kg, this is a multi-person installation into a genuinely large wall, not a retrofit into an existing standard opening. If 86SS is more scale than the room needs, the 68SS delivers a similar look with a lighter, single-burner build.
Flex 86SS questions, answered
Does the Flex 86SS need a chimney or flue?
No. It runs on bioethanol, which burns clean with no smoke, embers or soot, so there is nothing to vent. It frames into a wall or opening with zero clearance to combustibles - no masonry chimney, gas line or flue required.
Can the Flex 86SS be used both indoors and outdoors?
Yes, it is rated for both. Indoors it needs a room of at least 220m³.
How is the Flex 86SS installed?
It frames directly into a stud wall (wood or metal) or an existing hearth opening, with zero clearance to combustibles required around the frame. There is no gas line, flue or masonry work: once the opening is framed to size, the unit drops in and connects to nothing else. At 122kg (All Flame) it is a two to four-person lift into place depending on the model; check the exact figure on this page before planning your install.
What does the Flex 86SS actually cost to run for an evening?
A full 18 litre fill burns for 8-13 hours. We sell e-NRG bioethanol at £65 for a 20 litre carton, so a full fill is about £59 and a three-hour evening works out at roughly £14 to £22. There is no standing cost, since it only uses fuel while it is alight.
Which Flex size should I choose?
The 86SS is the first size in the launch wide enough to need two burners for its full-width All Flame configuration, doubling the room coverage of the single-burner 68SS All Flame. If 86SS is more scale than the room needs, the 68SS delivers a similar look with a lighter, single-burner build.
Which fuel does the Flex 86SS burn, and do you sell it?
It runs on e-NRG bioethanol, which we stock in 20 litre cartons. Bioethanol produces no smoke, embers or ash, so there is nothing to clean out after use.
Are there any accessories that fit the Flex 86SS?
Yes. Its twin XL900 burner takes the XL Baffles and Black Glass Charcoal, sold separately.
Is the Flex 86SS certified for indoor use?
Yes. This model is certified to EN 16647, the UK and EU safety standard for indoor bioethanol fireplaces.
Who the Flex 86SS is for
It is a good fit if:
- You are building a genuine architectural centrepiece, not a single-room feature: All Flame is rated for a 220m³ room, double the 68SS.
- Even its most reduced configuration still matches the smaller 68SS's full-width output.
Consider something else if:
- This is more scale than the room needs: the Flex 68SS delivers a similar look with a lighter, single-burner build.
- A multi-person installation into a large wall is not practical: at up to 122kg this is not a retrofit into an existing standard opening.
