Rheem S/S Concentric Tankless Venting
All indoor tankless gas water heaters must be vented vertically or horizontally to the outdoors using factory approved venting material (No other venting material is permitted).
When choosing an indoor location, you should consider the shortest venting distance to the outdoors. Consult your professional installer or Rheem for maximum venting distances.
Rheem offers many venting accessories to make your tankless water heater installation easy.
