BASO J992DXA-7221 Pilot Burner

As an experienced HVAC technician, you know that a stable pilot flame is the foundation of any reliable heating system. The BASO J992DXA-7221 Pilot Burner is a heavy-duty J Series replacement pilot burner engineered for consistency in both Intermittent Pilot Ignition (IPI) and Standing Pilot Ignition (SPI) applications. This assembly features a precision-machined .021" orifice optimized for natural gas pilot burner systems, ensuring a controlled fuel flow that meets ANSI Z21.20 standards. Constructed with a 430 stainless steel pilot tip and a plated steel body, this unit is designed to withstand high-temperature environments, with the tip rated for up to 1500°F. The factory-assembled Y90 series inlet fitting simplifies field installation, providing a secure, leak-free connection. Whether you are servicing a residential furnace or a commercial boiler, the BASO J992DXA-7221 provides the dependable flame rectification and ignition performance required by modern HVAC gas ignition parts specifications, ensuring the main burner ignites within the critical four-second window.

• Universal Compatibility: Optimized for use with both IPI and SPI systems, making it a versatile addition to any service truck.
• High-Temperature Durability: The 430 stainless steel tip and plated steel mounting bracket resist oxidation and thermal degradation in intense heat.
• Precision Performance: Features a .021" natural gas orifice that provides a stable flame for reliable thermocouple or flame sensor response.
• Standardized Fit: Pre-assembled with an inlet fitting to reduce labor time during HVAC pilot burner assembly replacements.

• Can this pilot burner be converted for use with Liquid Propane (LP) gas? While this model is factory-configured for natural gas with a .021" orifice, it is compatible with Y90AA-42xx series LP inlet fittings if the application requires a fuel conversion.
• What mounting configuration does the J992DXA-7221 use? It utilizes a robust mounting bracket designed for flexible positioning, though the ignition port should typically be mounted 1/4 inch above the nearest burner port for optimal ignition.
• Is this assembly compatible with standard thermocouples? Yes, this assembly is designed to work seamlessly with BASO lead-type thermocouples or flame sensors for proper safety shutoff functionality.
