Concentric venting utilizes an engineered pipe-inside-a-pipe design where combustion air is pulled in through an outer jacket while exhaust gases exit through the inner core in Hickory Hills, Illinois. This requires only a single hole through exterior walls or roofs. However, if inner exhaust seals fail, toxic exhaust gas recirculates directly into the fresh air intake, starving the burner and creating heavy soot. Our technicians specialize in concentric venting systems from Rinnai, Noritz, and Rheem. We inspect inner flue joints, replace silicone gaskets, and secure exterior wall caps. We keep your concentric system balanced and safe.

Our Rheem tankless system kept shutting down during showers with code 12. Two other plumbers told us we needed a new unit, but this team discovered a clogged condensate trap and an oxidized flame sensor. They cleaned the burner assembly and saved us thousands compared to a premature replacement.
