Description
Weil McLain 510-300-013 210°F Spill Switch — Manual Reset
The Weil McLain 510-300-013 is an OEM manual reset spill switch designed to protect boiler systems from the hazards of flue gas spillage. Calibrated to trip at 210°F, this safety device monitors the draft hood or flue outlet area and interrupts the burner circuit the moment it detects abnormally high temperatures caused by combustion gas rollout or backdrafting. Once tripped, the switch requires a manual reset, ensuring a qualified technician inspects and resolves the root cause before the appliance is returned to service.

Why Manual Reset Matters
Unlike automatic reset switches, a manual reset spill switch requires a deliberate action to restore operation after a fault. This design philosophy prioritizes safety — if the switch has tripped, it signals a potentially dangerous condition such as a blocked flue, inadequate combustion air, or heat exchanger failure. A technician must identify and correct the underlying issue before manually resetting the switch and restoring burner operation.
