Utica-Dunkirk PB-001.02 Pilot

The Utica-Dunkirk PB-001.02 is a precision-engineered Natural Gas Spark Pilot assembly designed for reliable ignition in high-efficiency gas-fired boilers and furnaces. This genuine OEM replacement part, often cross-referenced as the Honeywell Q345A or Q345A-1818, is a critical component for technicians maintaining commercial and residential hydronic systems. Built for the rigorous demands of the trade, the PB-001.02 spark pilot ensures consistent flame rectification and burner sequencing, preventing the intermittent ignition failures that lead to nuisance lockouts. As a boiler pilot assembly optimized for natural gas, it features a durable electrode and porcelain insulator designed to withstand high-combustion temperatures while protecting signal integrity to the ignition control module. For contractors performing a furnace pilot replacement or seasonal tune-up, this unit provides the exact fit and technical alignment required to restore factory-spec performance. Precise electrode positioning and robust construction make this Utica-Dunkirk pilot the professional choice for maintaining safe and efficient burner operation during the peak heating season.

• OEM Compatibility: Specifically engineered to match the technical requirements of Utica and Dunkirk boiler systems, ensuring seamless integration with existing gas valves.
• Optimized Ignition: High-grade electrode construction provides a stable spark for rapid gas ignition, reducing wear on the ignition transformer.
• Flame Sense Reliability: Designed for accurate flame sensing to keep the burner control energized and prevent unnecessary system shutdowns.
• Durable Construction: Features heavy-duty materials that resist carbon buildup and thermal stress, maintaining boiler ignition efficiency over long-term operation.
• Technical Accuracy: Eliminates the guesswork associated with universal parts by providing a direct factory-spec fit for natural gas applications.

Is the PB-001.02 compatible with Propane (LP) systems?
No, this specific assembly is optimized for natural gas spark pilot applications. Using it with propane may cause improper ignition and safety issues. Always verify the fuel type before installation.

What is the primary cause of clicking but no ignition with this pilot?
Usually, this indicates a cracked electrode or a dirty pilot orifice. If the spark is jumping to ground rather than the gas stream, or if the gas flow is restricted, the burner will fail to light.

Does this assembly include the ignition cable?
This is the pilot assembly itself. When performing a replacement pilot light install, it is standard practice to inspect the high-voltage lead for wear or grounding issues and replace it if the insulation is compromised.
