Velocity Boiler Works (Crown) 3514081 Pilot Assembly

The Velocity Boiler Works (Crown) 3514081 Natural Gas Pilot Assembly is the direct OEM replacement for the discontinued 3504080 pilot set. As an EI pilot assembly designed for high-efficiency application, it features a KF24 3/16-inch orifice and includes the necessary pilot tubing and spark wire for a complete field swap. This assembly is specifically engineered for Crown boilers, including the Aruba (AWR) series, ensuring your gas valve receives the correct flame rectification signal for safe burner ignition.

When performing a boiler repair or seasonal HVAC maintenance, replacing the entire pilot burner assembly is often more effective than attempting to clean fouled sensors. The 3514081 provides a stable natural gas pilot flame, critical for preventing nuisance lockouts and ensuring the ignition module operates within standard microamp parameters. Built with high-quality materials to withstand the high-temperature environment of a cast iron boiler combustion chamber, this genuine Velocity Boiler Works part maintains the original equipment specifications required for residential heating systems.

• Universal Direct Fit: Replaces 3504080 without cabinet modifications, utilizing standard Crown pilot mounting brackets.
• Complete Kit: Factory-integrated spark electrode and pilot tubing reduce installation time and potential leak points.
• Optimized Ignition: Specifically calibrated for natural gas boilers, providing a consistent ignition source for reliable startup.
• High Durability: Engineered to resist carbon buildup and electrode degradation in cast iron boiler environments.

Is the 3514081 compatible with LP (Propane) systems?
No, this specific assembly is calibrated for Natural Gas only. For LP conversions, a different orifice and pilot assembly are required.

Does this include the orange grommet for the burner door?
Most OEM replacement kits include the required mounting hardware and leads; verify your current pilot tube clip and grommet condition during the teardown.

Will this fix a "no flame" signal error on my Crown boiler?
If the pilot burner is lit but the boiler fails to stay on, this assembly provides the flame sensing needed to satisfy the control board's safety check.
