Used in low NOx heater models where the header must be removed or replaced, or the seal shows signs of wear or degradation.\u003c\/p\u003e\n\u003ch2\u003eInstallation \u0026amp; Compatibility Notes\u003c\/h2\u003e\n\u003cp\u003eBefore installation, shut off the heater and allow it to cool completely. Turn off any water flow and relieve system pressure. Remove the header assembly, clean the sealing surfaces thoroughly, install the new O-rings from the FDXLFOR1930 kit per the service instructions, reassemble the header and retighten to the manufacturer’s specified torque. Restart the heater and verify there are no leaks at the header connection.\u003c\/p\u003e\n\u003ch2\u003eWhy Choose This Kit?\u003c\/h2\u003e\n\u003cp\u003eSelecting the Hayward FDXLFOR1930 kit ensures you are using manufacturer-approved sealing components designed for the H-Series heaters.
