{"product_id":"hi-flame-alpha-inset-boiler-inner-grate","title":"Hi-Flame Alpha Inset Boiler Inner Grate","description":"\u003cp\u003eThe inner grate on the Hi-Flame Alpha Inset Boiler sits inside the grate frame and directly supports the fuel during combustion. It is the part most exposed to direct flame contact, so it degrades faster than surrounding components. Replacing a worn inner grate restores correct fuel bed support and maintains efficient burn performance.\u003c\/p\u003e\n\n\u003cp\u003e✅ \u003cstrong\u003eCompatible with:\u003c\/strong\u003e Hi-Flame Alpha Inset Boiler (AL357i)\u003c\/p\u003e\n\n\u003cp\u003e🔧 \u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eWeight: 1.27 kg\u003c\/li\u003e\n\u003cli\u003eMaterial: Cast iron\u003c\/li\u003e\n\u003cli\u003eHeat resistance: up to 650°C\u003c\/li\u003e\n\n\u003cli\u003ePart type: Boiler inner grate\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eThe inner grate allows primary air to pass through the fuel bed while supporting the load above.
