It regulates the flow and pressure of LP fuel to the burners, opening and closing on command from the furnace control to provide safe ignition and consistent heat. Because propane operates at different pressures than natural gas, this LP-specific valve is calibrated accordingly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e A failing \u003cstrong\u003e14C42\u003c\/strong\u003e may present as no ignition, intermittent lighting, weak or fluctuating flames, short cycling, or repeated safety lockouts.
