Laars Heating Systems Co. (Laars) is pleased to announce that their NeoTherm boiler and volume water heater models 80-500 are now certified to be common vented (up to 8 units) with each other, using Centrotherm InnoFlue polypropylene piping products.
Common vent systems
These common vent systems require Centrotherm InnoFlue components, as well as non-return valve kits that are now available from Laars. Each Laars kit contains one appliance adapter, one connector ring, one non-return valve, and centric increasers as needed.
Kit instructions show the manufacturer's part numbers for the required Centrotherm items and more detailed information about the common vent systems. The instructions are available on the Laars website.
