Laars Heating Systems 2400-138 Ignitor/Flame Sensor Assembly
The Laars Heating Systems 2400-138 Ignitor/Flame Sensor Assembly is a critical OEM replacement component designed for high-efficiency combustion control. Using a silicon carbide glow bar, this assembly provides reliable direct spark ignition and consistent flame rectification for Laars Summit SMB & SMW models, specifically sized at 200 and 250 MBH. As a veteran-grade HVAC replacement part, it integrates the igniter and sensor into a single robust housing to ensure precise flame signal monitoring—typically outputting between 5 to 30 microamps to the control board to prevent nuisance lockouts. This hot surface ignitor kit includes the necessary gasket kit to maintain a vacuum-tight seal on the burner plate, which is essential for the negative regulation gas valves found in Summit series boilers. When troubleshooting Error Code 110 or soft lockout conditions, replacing this OEM Laars igniter restores the proper ignition sequence and prevents unburned gas accumulation. Designed for the Teledyne Laars legacy, this assembly ensures your commercial or residential hydronic system meets original factory specifications for timing and safety.
Key Benefits for the Job Site- Direct OEM Compatibility: Engineered specifically for Laars Summit SMB-200, SMB-250, SMW-200, and SMW-250 boilers, ensuring a drop-in fit without field modifications.
- Durable Silicon Carbide Construction: The ignitor glow bar is built to withstand rapid thermal cycling and high-velocity premix burner environments.
- Integrated Flame Sensing: Consolidates the igniter and flame sensor to streamline the ignition control wiring and reduce potential points of failure.
- Complete Installation Kit: Includes the critical mounting gasket to ensure a proper seal and prevent combustion gas leakage at the mounting flange.
- Restores Signal Accuracy: Provides the necessary microamp feedback to the Boiler Control Board, eliminating intermittent ignition failures.
Which Laars models use the 2400-138 assembly?
This assembly is primarily utilized in the Laars Summit (SMB/SMW) series for 200 and 250 sizes. Always verify the part number in the specific unit’s service manual before installation.
What does it mean if my boiler shows Error Code 110?
An Error Code 110 typically indicates a "Failure to Light" or "Failure to Prove Flame." This often points to a cracked silicon carbide ignitor or a fouled flame sensor rod within the 2400-138 assembly.
Does this kit include the mounting gasket?
Yes, the 2400-138 kit includes the required gasket. It is professional best practice to replace the gasket whenever the ignitor assembly is pulled for inspection or replacement to maintain the combustion seal.
