Laars Heating Systems 2400-286 Hot Surface Ignitor
The Laars Heating Systems 2400-286 Hot Surface Ignitor with Gasket is a critical OEM replacement component engineered for high-performance ignition in Laars Pennant, HWG, and CB series boilers. This hot surface ignitor (HSI) serves a dual purpose in the combustion cycle: it provides a reliable heat source to initiate the burner and subsequently functions as a flame sensor for the integrated boiler control. Designed as a "new style" upgrade, the Laars 2400-286 is optimized for models ranging from 500 to 2000 MBH, including PNCH, PNCV, and MT2 series equipment. The inclusion of a high-temperature gasket ensures an airtight seal at the mounting flange, preventing combustion gas leakage and maintaining proper manifold pressure. For a successful service call, verify the 5-inch wire leads and Molex plug configuration matches the existing harness before securing the assembly with the provided porcelain wire nuts.
Key Benefits:
- Precise OEM Compatibility: Direct replacement for Teledyne Laars 2400-286, ensuring exact electrical resistance and physical fit for Pennant and Mascot systems.
- Dual-Function Technology: Operates as both an ignition source and a flame sensor, streamlining the combustion sequence and reducing part count within the cabinet.
- Enhanced Sealing: Comes with a dedicated replacement gasket to maintain the integrity of the combustion chamber and prevent air intrusion in hydronic loops.
- Rugged Construction: Built with high-grade silicon carbide to withstand rapid thermal cycling and high-velocity gas streams without premature fracturing.
- Simplified Installation: Features 5-inch leads with a pre-terminated Molex connector for quick "plug-and-play" integration into the control board.
Common Questions:
Which Laars boiler models use the 2400-286 ignitor?
This part is the standard ignition solution for several commercial and domestic lines, specifically the Laars Pennant (PNCH, PNCV, PNCP) 500-2000 models, as well as MT2H, MT2V, and MT2P series. It is also found in HWG and CB high-efficiency boilers.
Can I touch the ignitor element during installation?
No. Professional technicians should avoid touching the carbide element with bare hands. Skin oils can create "hot spots" that lead to localized stress and premature failure during the ignition trial. Always handle the part by the ceramic base.
What are the signs that my Laars ignitor has failed?
A failed 2400-286 usually presents as a "no flame" lockout. If the inducer motor runs but the ignitor fails to glow or shows a visible crack or white "hot spot" on the element, the circuit is likely open and requires immediate replacement.
