Buderus G115WS boilers can either be chimney vented or direct vented. All of the G115WS boilers that are sold on SupplyHouse.com come in a package ready for chimney venting. If you need the boiler with direct venting, please call our customer service representatives at 888-757-4774 and they can place a special order for the direct vent burner to go with the boiler that you need.
