The grate frame in the Warrior Olive is the outer cast iron carrier that forms the base structure of the firebox, holding the inner riddling grate in position and supporting the fuel bed. It takes sustained heat loads and can warp or crack after years of regular use, particularly on multi-fuel operation. Replacing it with this cast iron grate frame restores the original firebox geometry. ✅ Compatible with: Warrior Olive stove (boiler and non-boiler versions) 🔧 Specifications Material: Cast iron Heat resistance: up to 650°C Part type: Grate frame / carrier frame / outer grate frame The grate frame replacement requires removing all inner firebox components first. A warped or cracked frame can cause the inner grate to sit unevenly, which leads to poor ash riddling and inconsistent airflow beneath the fire. Fitting a replacement keeps the firebox in correct alignment and makes routine maintenance more straightforward.
