Please help. We had a wood burner installed in the summer and it is emitting a chemical smell when lit and on high. First we thought it was the paint baking on, but it's gone on for months now. I ve recently noticed that behind the burner the fire board that was put in had discoloured/scorched. Could this be the problem? Is the wood burner to close to the back of the chimney? (We can't put the burner on high as the smell is so bad)
