Weil McLain 381355515 - 381355515 Jacket Panel Kit, Left and Bottom, WTGO-4 S3, UL726

Maintaining the structural integrity and thermal efficiency of your heating unit is simplified with the 381355515 jacket panel. This kit is specifically engineered for WTGO-4 and WGO-4 series boilers to provide a robust housing that preserves internal heat energy and prevents exterior damage to critical cabinet surfaces.

This assembly fits securely onto the boiler cabinet, creating a protective barrier that seals the combustion chamber environment. By replacing damaged or missing panels, you prevent heat loss and ensure the unit maintains compliance with original thermal insulation standards during operation.

Key System Performance Baselines:

• Thermal Retention: Minimizes radiant heat loss from the boiler chassis to the ambient environment.
• Structural Alignment: Engineered to provide a precise fit for WTGO-4 series cabinet frames.
• Component Protection: Shields internal electrical and hydronic components from dust and environmental debris.
• Operational Safety: Ensures proper cabinet ventilation and isolation of hot internal surfaces.

⚠️ Application Profile: Specifically designed for maintenance and restoration of Weil-McLain WTGO-4 and WGO-4 series hydronic boilers requiring jacket component replacement.
