I don't know about other techs on this website but your question is certainly not pertinent to any knowledge I would have. We don't do work on fireplaces and so am totally ignorant of any questions along those lines. Sorry. In our area, we'd suggest you contact a chimney sweep or company that installs gas logs.
If YOU want change, YOU have to first change.
If you are waiting for the 'other guy' to change first, just remember, you're the 'other guy's' other guy. To continue to expect real change when you keep acting the same way as always, is folly. Won't happen. Real change will only happen when a majority of the people change the way they vote!
