Stainless Steel Class A Chimney for Wood stoves and fireplaces
For over 50 years, Security Chimneys International has been an innovator in the venting field and a market leader. Instrumental in the company's growth has been an ongoing focus on product improvement and the introduction of new, innovative products. This drive for excellence has given rise to the Secure Temp ASHT+, Stainless Steel Class A Chimney, one of the most popular lines of venting products in North America. This high-quality product ensures that end-users benefit from maximum safety and proven corrosion protection.
The arrival of controlled-combustion stoves led to the development of Security's Secure Temp™ asht+ high-temperature chimney. The asht+ was the first Stainless steel clas A chimney listed to standards established for temperatures of 2100°F when used with this type of appliance. Creosote buildup in a chimney can cause fires capable of reaching temperatures of up to 2100°F. The asht+, with its double-wall all-stainless steel chimney and exclusive Secure Plus insulation, minimizes heat loss through the chimney walls, and can withstand that intense heat. The free-floating inner lining is attached only to the male coupler at the top, expanding and contracting freely with temperature fluctuations. The external casing of the Secure Temp ASHT+ carries the structural load.
The use of stainless steel, selected for its resistance to high temperatures and corrosion, lends outstanding durability to the Secure Temp™ asht+ high temperature chimney. It is also available with an aluminum-zinc coated steel casing in 6-, 7-, and 8-inch inner diameters (I.D.). Chimneys in diameters of 5 to 10 inches feature 1 inch of superior-quality, high-density Secure Plus insulation. This exclusive insulation keeps the temperature of the outer casing relatively low, keeping safety features as simple as possible.
All Secure Temp asht+ high-temperature stainless steel chimneys, regardless of diameter, can be installed as close as 2 inches from combustible materials. The ASHT+ (5- to 10-inch diameters) also features fast and easy Twist-Lock assembly. Lengths and universal fittings fit together and lock into place by twisting one-eighth of a turn. No other part is needed to ensure the chimney's structural stability, keeping installation time to a minimum.
Security Chimneys International Ltd.™ warrants the factory-built Secure Temp asht+ stainless steel chimney for an unlimited time from the date of purchase. This warranty is limited to the replacement of chimney components provided they have been properly installed and used as intended.
