US - For high temperatures in negative pressure operation
Integrated balanced flue solution for modern interiors
The Schiedel US system is a modular concentric stainless steel system designed specifically for gas-fired heating stoves. Operating under negative pressure in dry conditions, it provides a safe exhaust path while drawing combustion air directly from outside.
Engineered with lightweight stainless steel inner and outer walls, the system ensures simple assembly and low structural loads. Available in standard stainless steel as well as specialized architectural color finishes, it allows seamless aesthetic integration into visible living areas.
