Laars Heating Systems 2400-040 Flame Holder Assembly
The Laars Heating Systems 2400-040 Flame Holder Assembly is a critical OEM combustion component engineered for high-efficiency thermal performance in H, HW, and HP series boilers. Designed to stabilize the burner flame and ensure uniform heat distribution across the heat exchanger, this assembly is vital for maintaining the combustion efficiency required in commercial and residential hydronic applications. The 2400-040 features a robust flame holder design that withstands high-temperature cycles, preventing premature degradation and ensuring a clean burn. This genuine Laars replacement part includes a burner gasket set to provide an airtight seal, preventing lethal flue gas leakage and maintaining the specific manifold pressure required for safe appliance operation. For technicians servicing Laars EBP or Endurance models, replacing a warped or clogged flame holder assembly is essential to resolving "no-light" conditions or inconsistent flame rectification signals often caused by carbon buildup or structural fatigue. Utilizing OEM Laars parts ensures the burner maintains its original factory specifications for NOx emissions and BTU output.
Key Benefits
- Precise Flame Stabilization: Engineered to hold the flame at the correct distance from the burner ports, preventing flame lifting or flashback.
- Complete Installation Kit: Includes high-grade gaskets to restore the critical seal between the blower assembly and the combustion chamber.
- Optimized Combustion: Improves fuel-to-air mixing, which maximizes AFUE ratings and reduces the risk of soot accumulation within the venting system.
- Direct OEM Compatibility: Specifically designed for Laars Heating Systems H, HW, and HP series to ensure manifold alignment and proper direct spark ignition.
Common Questions
How do I know if the flame holder assembly needs replacement?
Technicians should inspect the flame holder for warping, cracks, or excessive carbon deposits during annual maintenance. Signs of failure include uneven flame patterns, booming on ignition, or localized overheating on the burner tube.
Is this part compatible with natural gas and propane units?
Yes, the Laars 2400-040 assembly is designed for use in both natural gas and liquid propane (LP) configurations, provided the gas valve and orifices are correctly set to the manufacturer's specified manifold pressure.
Can I reuse the old gaskets when installing the 2400-040?
No. Reusing old gaskets increases the risk of combustion air leaks or flue gas bypass. This assembly includes the necessary gaskets to ensure a gas-tight seal during the combustion system overhaul.
