BASO J993MDA-2 Pilot Burner

The BASO J993MDA-2 Pilot Burner is a high-performance, multi-mount solution designed for standing pilot applications in residential and light commercial gas-fired equipment. This specialized #3 tip pilot assembly is engineered to provide a stable, consistent flame pattern that ensures reliable main burner ignition. Fabricated with a 430 stainless steel pilot tip capable of withstanding temperatures up to 1500°F and a durable plated steel mounting bracket, it is built for long-term survival in high-heat environments. The J993MDA-2 serves as a direct, universal replacement pilot burner for J10_DDA and J11_DDA (D10 and D11) series models and is functionally identical to the J993MDA-2H. Each unit includes a pre-installed natural gas inlet fitting (Y90AA-3223) and an LP gas inlet fitting (Y90AA-4213), allowing for seamless field conversion. The multi-mount bracket features three tapped holes on four sides, providing HVAC contractors with maximum vertical and horizontal adjustment flexibility during installation.

• Universal Compatibility: Serves as a versatile replacement for several J-series models, reducing the need to carry multiple SKUs on the service truck.
• Dual Fuel Ready: Packaged with both natural gas and propane (LP) orifices to accommodate various site requirements.
• Extreme Durability: The 430SS pilot tip resists oxidation and thermal fatigue, maintaining tip geometry over extended duty cycles.
• Flexible Mounting: Four-sided bracket design with multiple tapping points allows for precise pilot-to-main-burner alignment.

Is the J993MDA-2 compatible with LP gas systems?
Yes. While it comes with the natural gas fitting installed, a liquid propane (LP) inlet fitting is included in the package for field conversion.

How does this model differ from the J993MDA-2H?
The J993MDA-2 and the J993MDA-2H are identical in form, fit, and function; the "H" designation typically refers to specific packaging or internal manufacturer codes but does not affect technical performance or installation.

What are the mounting requirements for proper ignition?
For optimal performance, the pilot ignition port should be mounted approximately 1/4 inch above and 1/4 inch away from the center of the nearest main burner port to ensure a reliable thermocouple millivoltage output.
