Resideo Q3450B1112 Pilot Burner

The Resideo Q3450B1112 Pilot Burner is a critical replacement component designed for LP gas systems utilizing SmartValve technology. Specifically engineered for use with SV9500 and SV9600 series valves, this intermittent pilot assembly features a BCR-10 orifice with a 0.010-inch diameter to ensure precise fuel delivery and a steady 1,000 BTU/hr pilot flame. The Style B mounting bracket and left-hand front tip direction allow for accurate positioning within the combustion chamber, ensuring reliable ignition cycles even in demanding residential or commercial HVAC applications. This assembly includes a 30-inch ignition wire and a 1/4-inch compression fitting for a secure, leak-free connection. Technicians favor the Q3450B1112 for its intermittent pilot ignition efficiency, reducing fuel waste compared to standing pilots. When retrofitting or repairing Honeywell SmartValve systems, verifying the pilot burner orifice size and bracket configuration is essential for maintaining optimal equipment performance and safety.

Common Questions

Can I use the Q3450B1112 for Natural Gas applications?
No, this specific model is configured with a BCR-10 orifice for LP gas. Converting this assembly would require an orifice swap to meet the pressure and flow requirements of Natural Gas systems.

What is the purpose of the 3-lead ignition wire on this pilot?
The integrated 30-inch lead serves the dual purpose of high-voltage spark ignition and flame rectification, allowing the SmartValve system to monitor the pilot flame before opening the main gas valve.

How do I verify if the Style B bracket fits my furnace?
The Style B bracket is a standard mounting configuration for many Resideo and Honeywell burners. Technicians should compare the existing pilot bracket dimensions and tip direction (Left) to ensure alignment with the burner ports.
