UL 103 HT System
DuraPlus
DuraPlus is designed to stay cool on the outside, to provide a hot
draft on the inside, to boost stove eciency, and to provide for a
re-safe design that protects both the chimney and the building.
This triple-wall chimney features two insulating layers (ceramic
blanket, plus air space). The ceramic blanket insulation is held
securely in position, eliminating hot spots common with loose-ll
type insulations. In the event of a creosote re, the compressible
blanket insulation permits the chimney liner to expand outwardly
in a radial direction.
Designed for normal, continuous operation at 1000° F ue gas
temperatures, DuraPlus is subjected to rigorous and stringent HT
requirements of the UL standard, including one hour at 1400° F,
plus three ten minute chimney re tests at 2100° F.
