PLEASE NOTE: This Noritz tankless water heater has a model number designation which is similar to that of another model. As a result, they may appear to be the same units, but they are not the same. The parts are different and are not interchangeable between the units. To help ensure you order the correct parts, you must be sure that you select the model number which is a 100% exact match to your unit. A difference of 1 letter or 1 number in the model number will result in you ordering the incorrect parts for your unit.
