     Your chimney venting system has a big responsibility. It carries toxic gases out of your home, and while doing its job, it must withstand constant attack by acid, creosote and extreme temperature changes for years on end!

With the real risks of carbon monoxide poisoning and chimney fires becoming house fires, venting is a serious responsibility.

     The Ventis Class-A, All-Fuel Chimney System is built to handle the big and serious responsibility of safely venting your heating appliance. This system is manufactured in America, at our factory in Scranton, Pennsylvania. Ventis Class-A is made from 100% stainless steel on the inside and outside casing of each insulated pipe section. Each section is joined together by stainless steel hardware to ensure a secure, long-lasting venting system.

     The most respected and recognized testing laboratory in the world, Underwriters Laboratories, has tested and certified the Ventis Class-A system to exceed its standard for chimney safety (UL103HT). Ventis has been tested to withstand multiple chimney fires and still maintain structural integrity. Underwriters Laboratories testing and ongoing factory inspections is your assurance of safety and product quality for each and every Ventis system produced!

     Ventis is built to last and built to look good as well. Our mirror finish 430 stainless steel outer casing has a clean, attractive appearance. No Class-A system has as many rain cap options to meet your venting requirements as well as your personal taste. Our roof flashings, exterior wall support brackets and telescoping roof braces are available in optional all stainless steel to enhance its long-lasting beauty.

      A quality product is the foundation of an unsurpassed warranty. Ventis Class-A carries the exclusive Forever Warranty, the first Class-A warranty that is transferable to the next homeowner. No fine print in this warranty- just peace of mind.
