Weil McLain 382-200-411 Gas Valve Kit

The Weil-McLain 382-200-411 Gas Valve Kit is a field-proven solution for technicians servicing GV Series 4 high-efficiency cast iron boilers. This critical fuel delivery component ensures precise manifold pressure regulation and stable combustion across varying firing rates. Engineered for seamless integration, the kit features a high-performance direct spark ignition gas valve designed to maintain consistent BTU output while ensuring safety shut-off protocols are met. When diagnosing boiler ignition failure or erratic flame signals on a Weil-McLain GV boiler, replacing the entire valve assembly with OEM-spec components eliminates the risk of mismatched flow rates. This gas valve replacement restores the heating system to factory-standard performance levels, optimizing the air-to-gas ratio for maximum efficiency. The 382-200-411 is built to withstand the thermal stress of high-cycle residential and light commercial applications, providing reliable Honeywell gas valve technology tailored for the specific hydraulic and pneumatic demands of the Weil-McLain heat exchanger design.

• Broad Compatibility: Specifically calibrated for Weil-McLain GV Series 4 units, ensuring proper fitment and electrical connector alignment.
• Precise Pressure Control: Facilities accurate gas pressure regulation essential for maintaining stable combustion and preventing soot buildup.
• Direct OEM Replacement: Eliminates the need for field modifications, reducing labor time and ensuring the integrity of the safety string.

Common Installation & Troubleshooting Questions:

Does this gas valve kit fit all Weil-McLain GV boilers?
This kit is specifically designed for Series 4 models. While earlier or later series may use similar components, the specific O-ring and mounting hardware included here are tailored for the Series-4 configuration.

What are the symptoms of a failing Weil-McLain gas valve?
Common indicators include persistent "no ignition" lockout codes, audible clicking without flame production, or inconsistent manifold pressure that leads to poor combustion cycles.

How do I adjust the manifold pressure on this unit?
Adjustment should only be performed using a calibrated manometer. The pressure regulator is typically located under the cap screw on the valve body, and settings must align with the nameplate data for the specific altitude and gas type.
