Last week a part fell from the top inside of my wood stove. I think it fell because it has become warped. I put it back in place and it is fine for now. Don't know if it is necessary to replace it. I would like to find a used part if possible as I don't believe parts are made anymore for this stove. I am not sure the name of the part - maybe a baffle protector? It spans the top inside of stove to protect chimney from direct heat. Thank you for any direction given for my search. I believe the model number of stove is L 902320 Pt9 203? Trying to read with a mirror off back of stove - not so easy.
