Description
The Rheem-Ruud SP21001B Complete Combustion Assembly supplies the components required to generate and sustain the combustion process for gas-fired heating equipment. Integrating the burner, ignition, and airflow-related elements into a single assembly, it supports controlled fuel combustion within compatible HVAC systems while directing heat generation through the intended operating sequence. This assembly is installed inside the combustion chamber and connected to the fuel, ignition, and venting components of the unit. Coordinated combustion operation promotes efficient heat production, stable flame characteristics, and proper exhaust gas movement during heating operation.
