I purchased this LUAP Associates zero clearance insert last year and have fix some of the things that were wrong with it. I just recently installed it last weekend. My question is it has these two baffles in it and I do not know which way they are supposed to be positioned. The unit was taken apart when I picked it up and the people had just bought the home and the insert came with the home, they didn’t know anything about it. I have been searching online for the last week with hours on reading and looking at pictures and have not seen anything similar to the upper sliding baffle. Worst case scenario I will take both plates out and make a new baffle out of one plate. I have not installed the firebricks yet cause I don’t want to damage them while I’m finishing up everything.
