I was curious if any of you have any opinion, experiences, or heard of AcuCraft fireplaces? Acucraft website This is the exact product I was looking at: Acucraft - Series 50 Wondering if anyone had any thoughts. Also, they have a 10" insulated flu system which they utilize instead of a true masonry all the way up the stack. Any thoughts on that sort of setup? View attachment air.jpg Thanks for any advice.
