Unlike 68SS, 86SS, 104SS and 122SS, which each offer four configurations, the 158SS offers only two — All Flame or log boxes on both sides — with no single-side log box option.\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003e\u003cstrong\u003eDesign \u0026amp; Build:\u003c\/strong\u003e\u003c\/span\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eZinc-sealed mild steel surround and toughened glass, built around triple Grade 304 stainless XL1200 burners in All Flame form (45,870 BTU\/h combined from a 30-litre tank), stepping down to triple XL900 burners when log boxes sit on both sides.
