BASO J997MDA-2 Pilot Burner

The BASO J997MDA-2 Pilot Burner is a professional-grade standing pilot burner assembly engineered for high-demand HVACR heating applications. Featuring a #7 tip arrangement, this unit is designed for a precise 1500°F 430SS pilot tip to ensure reliable flame sensing and ignition for natural gas and LP systems. As a multi-mount solution, it includes three tapped holes in each bracket to facilitate accurate vertical adjustment in J10_DDA and J11_DDA type burners. This model is technically identical to the J997MDA-2H, offering a universal fit for varied appliance configurations. Built with plated steel components and a 0.850-inch "A" dimension, it maintains structural integrity under continuous operation. The package includes both natural gas and LP inlet fittings, allowing for seamless field conversion. For optimal performance in commercial or residential furnaces, ensure proper millivolt output testing using a standard Y99AB kit to verify the thermocouple circuit maintains a stable pilot flame.

• Universal Multi-Mount Design: Features mounting brackets on all four sides, allowing for adaptation to nearly any furnace or boiler system.
• Dual Fuel Compatibility: Ships with both natural gas and liquid propane (LP) inlet fittings included for immediate field flexibility.
• High-Temperature Durability: Equipped with a 430 stainless steel tip rated for 1500°F to resist oxidation and carbon buildup.
• Precise Flame Positioning: Employs a specific #7 tip position to optimize flame impingement on the thermocouple for consistent millivolt generation.

Common Questions

Yes, the J997MDA-2 and J997MDA-2H are functionally identical and serve as direct replacements for one another in standing pilot circuits.

This assembly is dual-fuel capable. It comes with a natural gas inlet installed and a separate LP gas inlet fitting for conversion.

The integrated mounting bracket contains three tapped holes, allowing technicians to perform vertical adjustments to align the ignition port with the main burner center.
