I completely finished my Pacific Insert install, its replacing my the Lopi Freedom I had installed in my family room. I have had a few fires with it now and could not be happier with its performance. I did make one small modification, I made a block that can open and close the air boost and reused the damper in my appliance damper. so far 8 to 8.5 hour burns I think 9 to 10 may be possible. The window stays very clean just wish it was bigger. LOL
