Ao Smith 100191112 Final Burner Assembly Kit 18 Inches 33 Dv Ng

Product Description

The AO Smith 100191112 is a final burner assembly kit designed for direct vent natural gas water heaters. This kit fits models with an 18-inch burner configuration and is rated for 33 units, making it a precise replacement part for specific AO Smith DV NG water heater models. Final burner assemblies are critical components in gas-fired water heating systems. The burner sits at the base of the tank and ignites the natural gas fuel to heat the water stored above it. Over time, burner components can corrode, warp, or clog due to mineral deposits, sediment, or extended use. Replacing the full burner assembly kit restores proper combustion, improves heating efficiency, and extends the service life of the water heater unit. This kit is built to OEM specifications, meaning it meets the same standards as the original part installed at the factory. HVAC technicians and plumbers use direct replacements like the AO Smith 100191112 to avoid compatibility issues and reduce callback rates after service calls. The direct vent configuration means the water heater draws combustion air from outside the building and exhausts flue gases through a sealed venting system. This design improves indoor air quality and increases efficiency compared to standard atmospheric vent units. Natural gas models like this one are common in residential and light commercial applications across North America. Using the correct burner assembly for your specific model ensures safe ignition, stable flame operation, and proper BTU output. Always verify the model number on the water heater data plate before ordering replacement burner parts.
