A burner system for gas-fired furnaces that includes a burner box having one or more burner heads. The burner box is linked to one or more heat exchanger tubes. A flame suppression tube extends from each of the one or more burner heads. The flame suppression tube extends in the direction of one of the one or more heat exchanger tubes. A space separates the flame suppression tube from the heat exchanger tube. A blower is configured to provide a mixture of flammable gas and air to the burner box. An air delivery means provides air in the space separating the flame suppression tube from the heat exchanger tube.
