Been there, done that, only it was with our new log burner, could not work out what the awful smell was when we first lit it up, it turned out to be the protective backing on the flu pipe which was supposed to be peeled off before lighting the fire in the fire box!!!!!!!!!!!!!!!!! Did we feel stupid, no one told us and it was invisible to the eye, we could have set the whole house on fire!!!!!!!!!!!!!!
