Lochinvar & A.O. Smith 100112348 Burner Assembly
The Lochinvar & A.O. Smith 100112348 Burner Assembly is a direct OEM replacement engineered for high-efficiency natural gas water heaters and commercial boilers. This 18-inch natural gas burner assembly features a precision-machined #37 orifice, designed to maintain the exact BTU output and flame stability required for optimal combustion. As a critical firing component, it replaces obsolete part number 9007905005, ensuring a seamless fit and restoration of factory-spec thermal performance. Constructed with a heavy-duty cast iron body and corrosion-resistant stainless steel components, this OEM burner kit provides the durability needed for high-cycle commercial applications. For technicians performing routine maintenance or emergency repairs, verifying the #37 drill size orifice is essential to match the manifold pressure and gas flow requirements of the specific appliance. This genuine water heater burner assembly ensures clean ignition and reduces carbon buildup in the combustion chamber, protecting the heat exchanger from premature fouling.
Key Benefits- Precise Gas Flow: Integrated #37 orifice ensures consistent natural gas delivery and efficient flame propagation.
- Direct OEM Match: Designed specifically as a replacement for Lochinvar burner and A.O. Smith 9007905005 configurations.
- Commercial Grade Build: Features stainless steel and cast iron construction for maximum thermal resistance and service life.
- Optimized Combustion: Restores factory fuel-to-air ratios to improve efficiency and reduce emissions.
What unit models are compatible with this burner?
This 18-inch assembly is primarily utilized in Lochinvar and A.O. Smith commercial gas water heaters. Because fitment depends on the specific serial number and generation of the unit, always cross-reference your data plate before installation.
Can this assembly be used for Propane (LP) conversions?
No, the 100112348 is calibrated specifically for natural gas with a #37 orifice. Using this assembly with liquid propane requires a different orifice sizing to prevent hazardous over-firing.
Does this include the pilot assembly or igniter?
This SKU focuses on the main 18-inch burner tray and orifice. Depending on the model, secondary ignition components may need to be sourced separately or transferred from the existing manifold.
This item is not eligible for free shipping.
