This low-capacity 710-series control generates its own power from the pilot, so it operates the main burner from a millivolt thermostat without house power. When the valve fails, the pilot may burn but the main burner will not open, or the heater will not respond to the thermostat. It is rated 250-750 mV with 1\/2-inch inlet and outlet, nominal 70,000 BTU capacity, and 3.5-inch water-column natural-gas regulation. Match the full equipment model, gas type, and control configuration before ordering.\u003c\/p\u003e\u003ch3\u003eProduct Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSKU:\u003c\/strong\u003e ER710-502\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of origin:\u003c\/strong\u003e China\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Millivolt, 250-750 mV\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnections:\u003c\/strong\u003e 1\/2-inch inlet and outlet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCapacity:\u003c\/strong\u003e Nominal 70,000 BTU\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRegulation:\u003c\/strong\u003e 3.5-inch water column, natural gas\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCompatible Part Numbers\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e710-502\u003c\/li\u003e\n\u003cli\u003e7000MVRLC\u003c\/li\u003e\n\u003cli\u003e731701424\u003c\/li\u003e\n\u003cli\u003e740701401\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect replacement:\u003c\/strong\u003e Replaces the listed millivolt gas valve part numbers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSelf-powered control:\u003c\/strong\u003e Millivolt design runs the burner from the pilot generator without house power.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorrect gas regulation:\u003c\/strong\u003e 70,000 BTU capacity with 3.5-inch water-column natural-gas regulation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard connections:\u003c\/strong\u003e 1\/2-inch inlet and outlet match the original control.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFixes These Symptoms\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePilot burns but the main burner will not light\u003c\/li\u003e\n\u003cli\u003eHeater will not respond to the millivolt thermostat\u003c\/li\u003e\n\u003cli\u003eHeater shuts off or produces no heat with a gas-control fault\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCompatible Brands\u003c\/h3\u003e\u003cp\u003eEmpire, Williams\u003c\/p\u003e\u003ch3\u003eCompatible Models\u003c\/h3\u003e\u003cp\u003eFits various models.
