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.

Configuration options	From 86SS upward, All Flame chains two burners (XL900 x2, 30,000 BTU/h, 18L, rated to 220m³) rather than one — the opening is too wide for a single burner to span. Log Box – Left/Right narrow to a single XL1200 (15,290 BTU/h, 10L, 115m³); Log Boxes – Both Sides narrows further to a single XL900 (15,000 BTU/h, 9L, 110m³). All four configurations are the same price.
