Overview:
- The Flex 42SS widens the opening to 1265mm on the XL700 burner, the same burner used in the wider Flex 60SS, giving a genuinely cinematic flame band without the largest sizes’ weight or price.
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 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, comfortably ahead of the 32SS's 80m³. Sharing its burner with the wider 60SS means the same flame intensity, just spread across a narrower 1265mm opening rather than the 60SS's 1725mm.
Trade-off worth knowing:
- At 60kg it’s a genuine two-person install, and 1265mm still won’t fill a wide feature wall the way the 50SS or 68SS do. If the wall is wide enough to take it, the 50SS gives noticeably more glass for a comparatively modest price step up.
