Again, I would like to thank those on this board for all of the excellent advice I received. I purchased this harman insert in August and was going to have it installed with a direct connect due to ignorance. My home was built in 1848 and after "speaking" with several members of this board I leanred that my 1848 home could be no longer if I did not install the unit properly. As a result, I had a full liner put in and am very pleased with the results. I have yet to burn, but plan on doing it this week as the nights are starting to get cool. Anyway, here are the pictures.
