Laars Heating Systems R20047801 Burner/Pilot Assembly
For high-demand commercial and residential hydronic applications, the Laars Heating Systems R20047801 Burner/Pilot Assembly is a critical OEM replacement engineered for precise Natural Gas spark ignition. This NG Spark Ign Burner/Pilot Assy integrates the pilot burner, spark igniter, and a high-response thermocouple into a single robust unit to ensure reliable main burner light-off and flame safety. Built to withstand the thermal stress of high-output cycles, the assembly R20047801 provides the consistent ionization signal required by the ignition control module to prevent nuisance lockouts and delayed ignition timing. As a direct Laars replacement part, it maintains the precise orifice alignment and gas-to-air mixture ratios necessary for optimal combustion efficiency across a wide range of atmospheric and high-efficiency platforms. Whether you are servicing a Mighty Therm or an AP series boiler, installing this genuine pilot assembly ensures the system operates within original manufacture specifications for gas pressure and safety monitoring.
Key Benefits- OEM Compatibility: Seamlessly integrates with Laars Mighty Therm, HH, AP, and PH series models, including sizes 2000 through 5000.
- Integrated Safety: Features a high-quality thermocouple that monitors pilot flame temperature to instantly cut gas supply if the flame is extinguished.
- Efficient Ignition: The spark ignition design eliminates the need for a standing pilot, reducing fuel consumption and operational costs.
- Durable Construction: Heavy-duty mounting bracket and leads are designed to resist carbon buildup and corrosion in high-temperature environments.
Is the R20047801 compatible with Propane (LP) systems?
No, this specific assembly is calibrated and orificed exclusively for Natural Gas (NG) applications. Using this in an LP system will cause improper combustion and safety hazards.
What are the signs that my current pilot assembly needs replacement?
Common indicators for technicians include consistent sparking without pilot ignition, failure to hold a flame signal, or visible corrosion on the igniter or sensors that prevents a clean spark.
Does this assembly include the high-voltage ignition lead?
Yes, the R20047801 burner pilot assembly typically comes pre-wired with the necessary leads for a direct "plug-and-play" connection to the control board.
