Resideo Q345A1313 Pilot Burner

For service technicians and contractors maintaining intermittent pilot systems, the Resideo Q345A1313 Pilot Burner serves as a critical OEM replacement for ensuring reliable ignition and flame sensing. This non-primary aerated combination pilot burner and ignitior is specifically engineered for use with natural gas systems, featuring a factory-installed BCR-18 (0.018") orifice. It is a drop-in direct replacement for 411-857-000 and 390686-25, providing a seamless retrofit for older furnace and boiler configurations. Designed for compatibility with Resideo/Honeywell S86, S860, S8610, and S8670 ignition modules, this assembly utilizes a single tip style with a left-facing front tip direction. The unit includes a ceramic-insulated Kanthal flame rod and spark igniter for high-temperature durability, a 1/4" compression fitting (0.78" length), and a B-style mounting bracket that can be converted to an A-style using the included hardware. Use this HVAC pilot assembly to restore precise flame pattern control via its adjustable 3-position hood.

Key Technical Benefits

• Broad Module Compatibility: Fully compatible with Honeywell S86 series intermittent pilot ignition modules for stable flame rectification.
• Field Conversion Ready: includes a special mounting bracket and screws to convert from a "B" bracket to an "A" bracket in the field.
• Engineered Sensing Performance: Equipped with a Kanthal flame rod and grounded strap to ensure consistent flame signal detection at the controller.
• Integrated Application Versatility: While optimized for natural gas with the BCR-18 orifice, the target style hood supports precise flame positioning across forced air furnaces and boilers.

Common Questions

Is this a direct replacement for my older Honeywell pilot assembly?
Yes, the Resideo Q345A1313 is the direct OEM replacement for model 411-857-000. It is specifically designed to work with the Honeywell S8610U and related intermittent pilot controls.

Does this unit support LP gas conversion?
This model is shipped as a natural gas pilot burner. While it supports LP applications, a specific LP orifice (sold separately) must be installed to maintain the correct BTU input and flame stability.

What is the orientation of the pilot tip?
This specific model features a single target-style tip with a left-facing front tip direction. For right-facing or front-facing applications, verify your specific bracket requirements before installation.
