Overview:
- The Flex 122SS is the first size in the Flex range to run three burners across its All Flame configuration, a 3310mm opening for a wall that needs to be the defining feature of the room.
Design & Build:
- Zinc-sealed mild steel surround and toughened glass, built around triple Grade 304 stainless XL900 burners in All Flame form (45,000 BTU/h combined from a 27-litre tank); every log-box configuration still runs twin burners rather than stepping down to one. 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 330m³ room. Even its most reduced configuration, log boxes on both sides, still runs twin XL900 burners at 30,000 BTU/h, matching the 86SS's own full-width All Flame output at a fraction of the wall space.
Trade-off worth knowing:
- At 3310mm and up to 172kg, this is a genuinely large-scale installation requiring a properly engineered wall. If 122SS is more than the space calls for, the 104SS gives most of the same architectural statement at a narrower width and lower price.
