Horse Flame Windsor Grate FrameThe grate frame for the Horse Flame Windsor boiler stove is the outer cast iron carrier that supports the riddling grate assembly inside the firebox. The Windsor boiler runs at higher sustained temperatures than the room heating variants, which puts additional stress on the grate components over time. This is a direct fit replacement for the original Windsor grate frame. Compatible with: Horse Flame Windsor (boiler model, HFB317) Specifications

Fitting a new one restores the correct temperature differential inside the firebox

allowing uncontrolled air into the firebox and smoke to escape around the door

Vermiculite rear bricks insulate the back wall and reflect heat forward into the firebox

air enters around the door rather than through the primary vent

undamaged glass panel is important for monitoring combustion and ensuring the door seals correctly during operation

✅ Compatible with: Henley Blasket stove

which is important for maintaining a consistent seal and preventing smoke from escaping around the door frame

A misaligned door caused by worn hinges will not close flush against the frame

as prolonged direct flame contact can permanently damage the stove body on a boiler stove running at sustained high output

Replace when cracked
