BASO J641DHA-4712 Pilot Burner

The BASO J641DHA-4712 Pilot Burner is a heavy-duty dual orifice pilot burner engineered for precise ignition in high-demand Liquid Petroleum (LP) heating applications. This specific model features a .012 orifice size, ensuring optimal fuel-to-air ratios for a stable, wind-resistant flame pattern. Designed as a direct replacement for the J641DHA-4712C, this intermittent pilot ignition component is built with a vertical mounting configuration and a bracket that allows for secure positioning within the combustion chamber. The dual-port design facilitates reliable pilot flame rectification, providing consistent signals to the flame sensor or thermocouple. For technicians servicing boilers, furnaces, or commercial water heaters, this OEM BASO pilot burner offers the tolerances required for accurate millivolt system troubleshooting and long-term HVAC gas valve compatibility. Its robust construction resists thermal degradation, maintaining the integrity of the ignition sequence under high-cycle operations.

• Precision LP Performance: Features a factory-calibrated .012 dual orifice optimized for Liquid Propane gas flow and stability.
• Direct Technical Interchange: Completely identical to the J641DHA-4712C, ensuring seamless mechanical and electrical integration.
• Professional Grade Durability: Constructed with high-grade alloys to prevent warping and carbon buildup at the pilot tip.
• Optimized Ignition Sequence: Engineered for high-efficiency furnaces and boilers requiring consistent pilot-to-main-burner flame transfer.

What is the difference between the J641DHA-4712 and the 'C' suffix version?
There is no functional or physical difference; the J641DHA-4712 is identical to the J641DHA-4712C and serves as a direct drop-in replacement.

Can this pilot burner be used with Natural Gas (NG)?
No, this unit is specifically configured with a .012 orifice for LP gas. Using it with NG would cause improper combustion and safety hazards.

Is the mounting bracket adjustable for different burner housings?
This model uses a standard vertical mounting bracket designed for specific HVACR appliance footprints. Always verify the bracket profile before field installation.
