Resideo Q345U1005 Pilot Burner

The Resideo Q345U1005 Universal Pilot Burner is a versatile intermittent pilot assembly designed for high-efficiency Honeywell pilot ignition systems. This single tip style burner serves as a direct drop-in for the 100110208 pilot assembly, streamlining truck stock for technicians servicing diverse residential gas appliances. Engineered for compatibility with both Natural Gas and Liquid Propane (LP) systems, it includes an adjustable front tip and features a robust U-style mounting bracket for secure positioning within the combustion chamber. The kit comes equipped with 1/4" and 1/8" compression fittings to accommodate varying gas line dimensions found in the field. By utilizing a high-grade OEM replacement pilot, contractors ensure reliable flame rectification and consistent bridge ignition, reducing nuisance service calls caused by pilot burner carbon buildup or failed spark-to-pilot sequences. This universal HVAC igniter assembly is built to withstand high-temperature cycling while maintaining precise millivolt output or flame signal strength.

• Universal Application: Replaces numerous OEM intermittent pilot burners, reducing the need for multiple SKUs.
• Flexible Installation: Includes 36-inch lead wires and multiple orifice options for NG and LP gas conversions.
• Dual Connection Sizes: Integrated 1/8" and 1/4" compression fittings allow for immediate adaptation to existing tubing.
• Optimized Flame Geometry: The single-tip adjustable design ensures proper impingement on the flame sensor or thermocouple for reliable ignition.
• Direct Cross-Reference: Specifically engineered to replace Honeywell Q345U series and Lochinvar 100110208 models.

How do I convert the Q345U1005 from Natural Gas to LP?
The unit includes both orifices. You must swap the pre-installed NG orifice for the LP orifice provided in the kit and tighten the compression nut to the manufacturer's torque specifications to ensure a leak-free seal.

Is this pilot burner compatible with standing pilot systems?
No, the Resideo Q345U1005 is designed specifically for intermittent ignition systems (IPI) and does not include the porting required for a standard standing pilot thermocouple application.

Will the U-style bracket fit non-Honeywell furnaces?
Yes, the universal U-style mounting bracket is designed with adjustable slots to align with various burner rack configurations common in modern gas-fired equipment.
