Armstrong Furnace R41948-002 Inshot Burner

The Armstrong Furnace R41948-002 Inshot Burner is a combustion unit that delivers a controlled air-fuel mixture into the heat exchanger section for ignition and sustained flame production. It uses a high velocity injection design to introduce gas into the burner throat, where it mixes with combustion air before ignition occurs. The burner body is shaped to maintain stable flame formation and consistent heat release during operation. In HVAC systems such as furnaces and gas fired heating units it contributes to combustion within the heating chamber. Positioned along the burner rack, it supports flame generation and heat production across the connected heat exchange pathway.
