Resideo Q345A1008/B Pilot Assembly

The Resideo Q345A1008/B Pilot Assembly is a precision-engineered intermittent pilot ignition component designed for service technicians addressing ignition failures in natural gas HVAC equipment. Formerly manufactured under the Honeywell brand, this non-primary-aerated burner assembly integrates a ceramic-insulated flame rod and spark igniter to provide stable flame sensing and rapid light-offs. Engineered for high-cycle reliability, the Q345A1008/B eliminates the need for a standing pilot, reducing gas consumption while maintaining UL Listed safety compliance. This pilot burner and ignitor combination features a durable mounting bracket and ground strap, ensuring a consistent electrical circuit for the flame rectification process. It is specifically built for compatibility with the S8600 and S8610 series modules, making it a critical stock item for contractors maintaining older Resideo intermittent pilot systems. By utilizing this genuine OEM replacement part, technicians ensure proper horizontal or vertical mounting alignment and factory-spec orifice sizing for natural gas applications.

Key Benefits for HVAC Contractors

• Universal Compatibility: Seamlessly integrates with S8600F, S8600H, S8600M and S8610U ignition modules for versatile field servicing.
• Industrial Build Quality: Features a non-primary-aerated design to minimize linting and clogging, ensuring a stable flame for the flame rod.
• Complete Assembly: Includes the pilot burner, spark igniter, and necessary wiring to simplify intermittent pilot burner replacement.
• Accurate Ignition: The ceramic-insulated ignition electrode prevents voltage leakage, ensuring a high-energy spark in high-moisture or varying temperature environments.

Common Technical Questions

Is the Q345A1008/B compatible with Liquid Propane (LP) systems?
No, this specific model is factory-configured for natural gas. For propane applications, a specific LP orifice conversion or a dedicated LP pilot assembly must be used to ensure correct BTU output and flame stability.

Can I use this assembly with a 24V intermittent pilot module?
Yes, the Resideo Q345A1008/B is specifically designed to work with 24V intermittent pilot ignition controls, including the popular S8600 and S8610 series Honeywell modules.

What causes a "no spark" condition even with a new pilot assembly?
Ensure the ground strap is securely fastened to the burner chassis. Without a solid common ground, the spark will not arc, and the flame sensing circuit will fail to detect the pilot flame.
