Fire valve external oil boiler plumbing advice

Fire valve external oil boiler We have an external grant vortex pro and the fire valve is on the oil supply line 1.4m away from the boiler . Read somewhere should be a distance of minimum 1 metre away .

The sensor end is clipped into clip above the burner correctly . Just wondered if the fire valve should be closer or if that’s ok at 1.4m

Thanks .
