A method delivers fuel gas to a furnace combustion chamber from a premix burner having a reaction zone with an outlet to the furnace combustion chamber. This includes the steps of injecting a premix of primary fuel gas and combustion air into the reaction zone, and combusting the premix to provide combustion products including vitiated combustion air in the reaction zone. Further steps include injecting staged fuel gas into the reaction zone separately from the premix, discharging the staged fuel gas and vitiated combustion air from the reaction zone through the outlet to the furnace combustion chamber, and combusting the staged fuel gas and vitiated combustion air in the furnace combustion chamber. This enables low NO
