Size: 8" x 36"
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 inch thick, yet provides 17 times the insulating valve of brick
This optimum density of insulation stops expansion noises and resists and contains surges of heat
This allows the system to be enclosed with only 2 inch clearance to combustibles
The "solid pack" density comprises about 85 percent air
The mixture of extremely fine fibers trap this air in the pores of the insulation and also blocks radiation heat transfer
Tested to 2100 degrees F
