Weil McLain 381-354-519 - 381-354-519 Insulation Kit for CG6

Maintaining proper thermal containment is critical for boiler longevity and performance, which is why the Weil-McLain 381-354-519 insulation kit serves as an ideal solution for your CG6 series heating units. By utilizing high-quality, factory-spec materials, this kit ensures that your boiler maintains internal temperatures more effectively, which reduces standby heat loss and lowers overall fuel consumption during operation.

This insulation assembly works by creating a robust thermal barrier around the boiler heat exchanger and internal cabinet. By sealing gaps and replacing degraded material, the kit prevents convective heat transfer from escaping the unit, ensuring that the energy produced by the burners is directed exclusively into your hydronic heating loop rather than being lost to the ambient surroundings.

Key System Performance Baselines:

• Thermal Retention: Minimizes standby loss for improved seasonal energy efficiency ratios.
• Heat Containment: High-density material composition ensures durability under consistent thermal cycling.
• Precision Engineering: Manufactured to specific Weil-McLain tolerances for a secure, airtight fit within the CG6 cabinet.
• System Compatibility: Fully compatible with CG6 models, including 113-071-365 and 113-071-369 configurations.

⚠️ Application Profile: Recommended for HVAC service technicians performing routine maintenance, refurbishing aging CG6 equipment, or restoring units that have experienced damaged or loose insulation panels during internal repairs.
