M&G DuraVent Obtains Approval for Bosch Thermotechnology’s Greentherm Series, Models C 950 ES and C 1050 ES, and Therm C1210 ES and C1210 ESC for use with Concentric PolyPro


April 1, 2013


Vacaville, CA – M&G DuraVent announced today that it has obtained a key approval for PolyPro Venting Systems. Bosch Thermotechnology has now approved PolyPro Concentric for their new gas tankless water heater Greentherm Series, Models C 950 ES and C 1050 ES and for Therm C 1210 ES and C 1210 ESC. Polypropylene venting provides the simplest and quickest venting option possible for a condensing tankless unit.


The Greentherm Series is approved for three new Polypropylene (PP) venting systems: concentric up and out, twin pipe, and common venting of up to four appliances. Bosch provides complete venting kits for each approved venting systems.


In addition to Greentherm C 950 ES and C 1050 ES, Bosch has also approved PP venting for condensing cascades for models Therm C 1210 ES and C 1210 ESC. Bosch’s common venting kits are offered either side by side or back to back configurations, allowing for a single vent pipe for all units.


PolyPro is an engineered system specifically designed for venting heating appliances. Gasketed joints require no primers or adhesives and easily assemble in seconds with just a splash of water. Terminations are designed for superior performance in poor environmental conditions. PolyPro is tested and listed to the ULC S636 standard in Canada and rated as a Class IIA, IIB, and IIC vent system. PolyPro offers the only double-wall polypropylene flex in the U.S., making it durable for relining masonry chimneys, factory-built chimneys, and useful for relining B-vent pipe when retrofitting it to use as a chase. PolyPro is superior in performance and easier to install than PVC or CPVC pipe, which were designed for irrigation, not venting. PolyPro has been successfully venting appliances in Europe for over 15 years.
