Heil Quaker ICP 605752 Pilot Assy

The Heil Quaker ICP 605752 Pilot Assy is a critical OEM replacement part designed for intermittent pilot ignition systems in residential and commercial gas furnaces. This Honeywell Q348A series pilot burner features a batwing tip style with a dual-wing 1-inch wingspan, ensuring optimal flame stability and reliable carryover to the main burner. Engineered with a durable Kanthal flame rod and a high-temperature ceramic insulator rated up to 1775°F, this assembly provides a consistent 15,000V open-circuit spark for rapid ignition cycles. It includes a Style B mounting bracket, an NE22 natural gas orifice (0.022-inch), and a 1/4-inch compression fitting, making it a drop-in solution for ICP specialty parts. As a veteran-grade HVAC pilot assembly, it is compatible with a wide range of Heil, Tempstar, and comfortmaker units utilizing Honeywell intermittent ignition control modules. Replacing a fouled or cracked Q348A1002 pilot ensures the high-tension ignition cable maintains an 1/8-inch spark gap, preventing nuisance lockouts and ensuring precise flame sensing for the control board.

Key Benefits:

• Broad Compatibility: Direct OEM replacement for ICP 605752 and Honeywell Q348A series used in Heil, Tempstar, and Arcoaire furnaces.
• Precision Engineering: Equipped with a 0.022 NE22 orifice specifically calibrated for natural gas applications.
• High-Heat Durability: Features a Kanthal electrode and ceramic insulation designed to withstand extreme combustion chamber environments without electrical leakage.
• Reliable Sensing: Integrates an igniter-sensor rod that provides immediate flame rectification signals to the ignition module to prevent gas buildup.
• Complete Kit: Includes the Style B bracket and primary aeration components for streamlined field installation.

Common Questions:

What causes a Q348A pilot assembly to fail?
Carbon buildup on the flame rod or a cracked ceramic insulator are the most common failure points. A cracked insulator allows the spark to arc to the grounded bracket instead of the pilot hood, resulting in ignition failure or erratic sensing signals.

Can this pilot assembly be used with Propane (LP)?
This specific model comes with a natural gas orifice. For LP conversions, you must swap the NE22 orifice for the manufacturer-specified LP orifice to ensure the correct BTU output and flame pattern.

How do I ensure the best flame signal after installation?
Ensure the pilot flame envelops 3/8 to 1/2 inch of the igniter-sensor tip. Also, verify that the ground strap is securely fastened to a clean metal surface to complete the rectification circuit.
