DuraTech chimney pipe is designed for appliances that are tested and listed for use with a 2100° F HT chimney system, such as woodstoves, fireplaces, furnaces, boilers, stoves, ranges, water heaters, or other appliances fueled by wood, oil, coal, or gas. The DuraTech chimney System is designed to stay cool on the outside and provide a hot draft on the inside. A fire-safe design protects both the chimney and the building. To calculate installed length of 5", 6", 7", or 8" DuraTech Chimney, subtract 1 +" from each joint overlap of chimney pipe. DuraTech's Light-weight insulation and sleek 1" wall design, combined with twist-lock fittings, provides for easy installation. No locking bands or mechanical fasteners required.
Product Note:Allow a 2" clearance to combustibles when installing a DuraTech Chimney.
DuraTech is a double-wall, all-fuel chimney system for use with wood stoves, fireplaces, furnaces, boilers, ranges, water heaters, or other appliances fueled by wood, oil, coal, or gas, and zero-clearance fireplaces that are factory-built.

With a Thermal Tech blanket insulation encased between duel walls, DuraTech offers superior safety and performance. It keeps the outer wall cool while ensuring high flue gas temperatures for optimum draft performance. The inner wall is 25% thicker than competitive chimneys, for an extra margin of safety. Designed for normal, continuous operation at 1000°F flue gas temperatures, DuraTech is subjected to rigorous and stringent HT requirements of the UL standard, including one hour at 1400°F, plus three ten minute chimney fire tests at 2100°F.
