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.
