I just installed a Waterford Leprechaun 90 OSA, and I'm having trouble fitting the fire fence back into place, as some deterioration of the fire brick is blocking the channel it's supposed to go in. My question is, does anyone know what this part is supposed to do on this stove? I.e. will using the stove without it make the stove run hotter/faster, slower, or just less efficiently, or is it more about keeping the glass clean? Here is a diagram of the air flow from the manual with the profile of the fire fence highlighted in pink. If anyone can shed any light on this, I'd appreciate it! Thanks.
