SMITH 100304360 is a manifold door assembly designed for natural gas water heater systems configured for Low NOx operation. This assembly serves as the front-facing combustion chamber closure, housing and aligning the burner manifold components that deliver fuel to the heat exchanger. It provides a sealed interface between the gas train and the combustion chamber, maintaining proper airflow and fuel distribution during operation. Licensed plumbers and HVAC technicians typically handle replacement of this assembly during combustion system servicing or burner compartment repairs.\u003c\/p\u003e\n\u003cp\u003eThis manifold door assembly is suited for residential and light commercial natural gas water heater applications where Low NOx burner configurations are required. Low NOx designs are commonly mandated in air quality management districts that impose emissions standards on water heating equipment. This part is intended for use in units requiring the OEM manifold door configuration to maintain proper combustion geometry and emissions compliance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eConfigured for natural gas fuel supply systems\u003c\/li\u003e\n  \u003cli\u003eLow NOx design supports compliance with regional emissions requirements\u003c\/li\u003e\n  \u003cli\u003eOEM-style manifold door assembly for direct replacement\u003c\/li\u003e\n  \u003cli\u003eMaintains combustion chamber seal for proper burner operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement manifold door assembly for A.O.
