does anyone know if the back sloped baffle plate inside the firebox for a Jotul combifire No.4 is still available for purchase? I have one of these stoves in my cabin and it’s a heating machine. However after eating cords after cords of wood the back baffle is starting to bow a bit and is letting some heat escape directly up the chimney. The rest of the stove is rock solid and I’d hate for this to be its demise.
