Lochinvar & A.O. Smith 100110704 Swordfish Burner

The Lochinvar & A.O. Smith 100110704 Swordfish Burner is a precision-engineered combustion component designed for high-efficiency commercial boilers and water heaters. This stainless steel burner assembly is a direct OEM replacement part, primarily utilized in Lochinvar Knight and A.O. Smith Cyclone series units. Engineered to maintain tight flame patterns and optimal fuel-to-air ratios, the 100110704 ensures consistent BTU output while minimizing NOx emissions. For technicians performing heat exchanger maintenance, replacing a compromised burner is critical to preventing soot accumulation and ensuring quiet ignition cycles. The Swordfish burner design facilitates uniform heat distribution, which is essential for protecting the combustion chamber liner from hot spots. Whether you are servicing a commercial condensing water heater or a high-capacity hydronic boiler, this burner provides the structural integrity required to withstand high-temperature thermal cycling without warping or degradation.

• OEM Compatibility: Precision-fit for Lochinvar 100110704 and A.O. Smith 100110704 models, ensuring no field modifications are required.
• Durable Construction: High-grade stainless steel resists oxidation and thermal fatigue in demanding commercial environments.
• Optimized Combustion: Maintains burner flame signal stability to prevent nuisance ignition lockouts and pressure switch trips.
• Efficiency Restoration: Restores the unit to original factory thermal efficiency ratings by ensuring a clean, complete burn.

What are the signs that a Swordfish burner needs replacement?
Technicians should look for visible cracks in the burner mesh, significant discoloration, or "hot spots" on the burner surface. Additionally, if you observe unstable flame rectification signals or delayed ignition, the burner may be compromised.

Is this burner compatible with both natural gas and propane units?
Yes, the 100110704 is designed to function with both fuel types; however, you must ensure the gas valve orifice and manifold pressure are calibrated to the specific fuel source as per the manufacturer's technical manual.

Does this assembly include the mounting gasket?
While the 100110704 is the primary burner assembly, it is professional best practice to inspect and replace the burner mounting gasket during installation to ensure a gas-tight seal at the blower interface.
