Rinnai equipment includes boilers and combi systems, and the parts only fit when the model match is exact. The quickest way to avoid ordering the wrong gasket, sensor, ignitor, or control is to start with the full model number from the manufacturer label.

SupplyHouse carries Rinnai replacement parts for supported models, including service items like heat exchanger gaskets, condensate components, safety valves, and installation kits.

Enter the model number exactly as printed on the label. Matching the complete model number is the fastest way to land on the correct gasket, sensor, ignitor, or kit.
