Yes, that helps. It sounds like the main improvement will be to try the hallway fan test this fall. If it works well, I have posted in the past about ways to duct this through the basement for more even heat distribution into the bedrooms. To start though, the fan test is easy.Safety wise I am good with my setup, and easy enough for me to clean the liner once or twice a season. Behind the insert- I believe it is called a heatilator, ? Something like that anyway. The fireplace brick is shielded with a metal box on the back and sides of fireplace. There is insulation between the metal box and brick, original construction I believe and I left this in place as it is in good condition and cleaned up nicely before installing the insert. Hope my description there is understandable.
