I looked through the q/a section, and searched the forum, but I haven't seen exactly what I am looking for. I am installing a SS liner into the chimney where my prefab/double wall flue is/was. I pulled out the prefab, removed all the wooden framing, and then had my uncle, a mason come over, and we laid one course of block, and firebrick to bring everything up to code. I have purchased a 7" liner and heat wrap(1") to go inside my existing 12"outer/8"inner double wall setup, as specified by my local chimney sweep. Question is, at the top of the chimney, i know i want to block off the space between the 7"and 8". On a masonry chimney, you would just fill it with cement or whatever they suggest. For this setup, should I just use the fire wrap and stuff it between the two pipes? I know it needs to be sealed off, I'm just not sure if I should use the high temp wrap or not. Any help would be appreciated. Thanks
