Weil McLain 383-500-395 Kit

The Weil McLain 383-500-395 Cover Plate Replacement Kit is a critical OEM maintenance assembly designed specifically for Ultra Gas Boiler models, including sizes 155, 230, and 310. As technicians know, a compromised combustion chamber boundary lead to drafting issues and inefficient heat exchange. This comprehensive condensing boiler repair kit includes a heavy-duty cover plate, a high-temperature cover plate gasket, a burner gasket, and all necessary mounting hardware to ensure an airtight seal. Restoring the structural integrity of the heat exchanger housing via this kit is essential for maintaining proper electrode positioning and preventing flue gas leakage. By replacing warped or corroded plates with this genuine Weil McLain part, you ensure the unit meets factory combustion specifications and maintains peak fuel-to-air ratios. Utilizing this boiler service kit during annual maintenance prevents emergency lockouts and simplifies the cleaning process of the internal heat exchanger pins.

• OEM Precision: Guaranteed 100% compatibility with Weil McLain Ultra Series 155, 230, and 310 units.
• Complete Assembly: Includes 383-500-395 hardware and gaskets to ensure a single-visit repair without sourcing extra seals.
• Combustion Integrity: Restores factory-spec sealing to prevent CO leakage and maintain proper ignition electrode geometry.
• Thermal Protection: Durable construction resists high-cycle thermal stress typical in high-efficiency hydronic heating systems.

• When should the cover plate be replaced versus just the gasket? Technicians should replace the entire plate if there is visible warping, heavy pitting on the flange surface, or if the mounting studs have snapped during disassembly.
• Is this kit compatible with Series 1 and Series 2 Ultra boilers? Yes, this replacement burner cover is designed to fit the heat exchanger dimensions for various Ultra Gas generations within the 155-310 size range.
• Does this include the insulation board? While standard kits focus on the plate and gaskets, it is highly recommended to inspect the internal refractory insulation and replace if cracked or moisture-damaged.
