The Grand Canyon 700-506 Millivolt Valve – NG 300K BTU (No Pilot Assembly) is a high-capacity natural gas control valve intended for use in millivolt standing-pilot systems. Rated up to 300,000 BTU, it is designed for larger Grand Canyon burners and fire features that require a robust NG valve but use a separate pilot assembly, which is not included with this part.
As an OEM replacement valve, the 700-506 is used when the original millivolt valve has failed, become damaged, or no longer regulates gas flow correctly. It should only be installed on compatible Grand Canyon systems by a qualified gas technician, following the burner and control documentation to ensure correct pressure, BTU capacity, and safe operation.
