Baso J974EKW-7218 Pilot Burner

The Baso J974EKW-7218 Pilot Burner is a reliable aerated pilot burner assembly specifically engineered for high-efficiency natural gas HVAC systems. Featuring an internal fitting design and a factory-calibrated .018" orifice, this component ensures a stable, clean sapphire-blue flame for consistent thermocouple or thermopile immersion. The J974 series is recognized by field technicians for its robust bracket construction and precise secondary air entrainment, which prevents carbon soot buildup and premature pilot outage. This OEM replacement pilot is essential for maintaining flame rectification standards in residential and commercial heating equipment. When replacing a clogged pilot orifice or a corroded burner head, the J974EKW-7218 provides the exact BTU output required for safe and reliable main burner ignition. Its compatibility with standard Baso gas valves makes it a staple for contractors performing seasonal maintenance and emergency repairs on gas-fired furnaces and boilers.

• Precision .018" Orifice: Pre-installed and optimized for natural gas flow rates to maintain a stable pilot flame.
• Advanced Aeration Design: Prevents linting and ensures proper air-to-fuel ratios for clean combustion.
• Integrated Mounting Bracket: Designed for universal compatibility and secure positioning near the main burner ports.
• Industrial Durability: Built to withstand high-temperature environments without warping or losing alignment.

Is this pilot burner compatible with LP gas systems?
No, the J974EKW-7218 is specifically configured with an .018" orifice for natural gas applications. A specific conversions kit or an LP-rated burner is required for propane use.

What is the primary cause of flame instability on this model?
Most issues stem from a dirty pilot orifice or obstructed primary air inlets. Ensure the area is clear of debris to maintain the correct flame signal.

Does this assembly include the thermocouple?
This is the pilot burner assembly only. It is designed to accept standard thermocouples or thermopiles but does not include the sensing element itself.
