The unique concentric venting system by Rinnai and Ubbink provides ease of installation as well as maximum performance and safety.
This vent is concentric which means that it has a pipe within a pipe. You only need to drill a single hole through the wall to install this vent. Fresh air comes into the heater through the outside pipe while used air is exhausted through the inside pipe. It lets you install an indoor Rinnai heater virtually anywhere in your home.
