Lochinvar & A.O. Smith 100111336 Burner Assembly
The Lochinvar & A.O. Smith 100111336 Burner Assembly is a critical OEM replacement part engineered for high-recovery natural gas water heaters. This NAT 16-inch burner assembly features a precision-drilled #37 orifice, ensuring calibrated gas flow and optimal BTU output for consistent combustion. Designed specifically for Series 200 and 201 units, it integrates seamlessly with Hot Surface Ignition (HSI) control valves, providing a reliable spark for efficient ignition cycles. Professional contractors utilize this assembly to resolve common "no heat" calls or unstable pilot symptoms in residential and light commercial applications. The robust construction and exact manifold alignment facilitate a direct-fit installation, reducing bench time and ensuring the unit meets factory performance benchmarks. This replacement burner assembly is the primary solution for 40-gallon high-efficiency models, maintaining the manifold pressure and combustion integrity required for safe, long-term operation in demanding environments.
Key Benefits- Precision Gas Regulation: The integrated #37 orifice provides the exact fuel-to-air ratio required for clean, efficient natural gas combustion.
- Enhanced Compatibility: Engineered as a direct replacement for A.O. Smith GCV-40, XCV-40, and GCVH-40L models, ensuring a perfect seal and venturi alignment.
- Reduced Labor Time: The 16-inch final burner assembly comes pre-configured for HSI systems, streamlining the swap-out process for field technicians.
- Industrial-Grade Build: Constructed with heavy-duty materials to resist thermal stress and corrosion within the combustion chamber.
Which water heater models are compatible with the 100111336 burner?
This 16-inch assembly is specifically designed for A.O. Smith and Lochinvar Series 200/201 natural gas water heaters, including popular 40-gallon models like the GCV, XCV, and GVR series.
Does this assembly work with Propane (LP) systems?
No, this is a natural gas burner assembly. Using a #37 orifice on an LP system will cause dangerous over-firing; always verify fuel type before installation.
When should a technician replace the entire burner assembly instead of just the orifice?
Replacement is recommended if the burner ports are clogged with scale, the manifold tube is compromised, or if the mounting plate/door assembly shows signs of heavy oxidation or warping.
