The Heil Quaker ICP 1149522 Pilot Orifice is a high-precision component engineered for reliable ignition in natural gas systems. Manufactured by International Comfort Products, this 10-pack of pilot orifices is a critical maintenance item for contractors servicing furnaces, boilers, and water heaters. The 1149522 is the direct OEM replacement for pilot orifice 503211, ensuring exact physical dimensions and gas flow rates required to maintain a stable blue cone pilot flame. These orifices are essential for keeping the thermocouple or flame sensor properly engaged, preventing nuisance lockouts and intermittent heating cycles. Designed to meet the stringent requirements of ICP replacement parts, this kit allows technicians to address clogs caused by soot, debris, or moisture without having to replace the entire pilot burner assembly. Whether you are performing routine maintenance or troubleshooting natural gas furnace ignition issues, having this bulk pack on hand ensures you have the 1149522 gas orifice needed for a professional, code-compliant repair across various Heil, Tempstar, and Comfortmaker models.

• Precise Gas Regulation: Specifically calibrated for natural gas to ensure optimal flow and a steady ignition source.
• Broad Compatibility: Serves as the official replacement for legacy part number 503211 across multiple ICP brand families.

• What causes a natural gas pilot orifice to fail or require replacement? Over time, dust, airborne debris, or residue from the gas supply can clog the small opening of the pilot orifice, leading to a yellow, weak flame that fails to activate the thermocouple.
• Is the ICP 1149522 compatible with LP (liquid propane) systems? No, this specific part is designed for natural gas applications only. Using it with LP gas can result in improper combustion and safety hazards.
• Will this part fit other HVAC brands besides Heil? Yes, as an ICP 1149522 OEM part, it is compatible with several sister brands under the International Comfort Products umbrella, including Tempstar, Arcoaire, and Comfortmaker.
