Highlights:

• Size: 8" x 9"
• No. 8T-9
• Type A chimney
• Low-K insulation density: 23 lb./cu. ft. average
• Model SS-II Type HT sizes 6" & 8" use the letter "T" in the part number
• Type HT chimney pipe special augured in mineral wool insulation filling the space between stainless steel walls is only 1 in thick yet provides 17 times the insulating value of brick
