Category IV PVC venting is now available for Raypak’s new XTherm™ Condensing Boiler. The company has vaulted the optional selection of stainless-steel, CPVC or PVC venting to the 2000 MBtu level, even for its 98% efficiency rated boilers. The PVC adaptor is factory installed inside the boiler jacket. For single- and multiple-boiler systems, this can reduce installation cost 30-50% while retaining all the energy saving benefits of condensing boilers.
