Overview:
- The Flex 78SS is a 2186mm-wide single-sided insert that ships with log-storage boxes built into both sides of the opening as standard — the only configuration MAD sells at this size, unlike the neighbouring 68SS and 86SS which both offer a choice.
Design & Build:
- Zinc-sealed mild steel surround and toughened glass, built around a Grade 304 stainless XL700 burner delivering 13,650 BTU/h (14.4 MJ/h) from a 7-litre tank, the same burner as the narrower 42SS and 60SS. 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:
- Runs 9 to 12 hours per fill and is rated for a 90m³ room, identical figures to the 42SS and 60SS despite the much wider 2186mm frame, since all three share the same XL700 burner. The built-in log boxes on both sides give genuine display storage without needing to choose a side.
Trade-off worth knowing:
- At 108kg it needs a proper multi-person install, and because the log boxes are fixed rather than optional, you can’t get a wider unbroken flame band at this size — the 68SS All Flame or 86SS All Flame configurations deliver that instead, at their own widths and burner outputs.
