Why Buy From Us
Every quote personally reviewed. Direct sourcing from top manufacturers.
Optimizing combustion performance in commercial heating systems, the 381-800-446 vent damper assembly is engineered specifically for Weil-McLain EGH-95 and EGH-105 boilers. This precision-fitted accessory integrates directly into the flue path to regulate exhaust flow, preventing the escape of heated air during standby intervals.
The unit operates by automatically closing the vent when the burners are inactive, effectively sealing the heat within the boiler cabinet. By retaining thermal energy between heating cycles, the assembly mitigates energy waste and lowers overall operating expenses for high-capacity hydronic systems.
Key System Performance Baselines:
- Energy Retention: Reduces standby heat loss by sealing the flue during idle phases.
- Model Compatibility: Engineered for precise fitment on EGH-95 and EGH-105 series boilers.
- Flow Regulation: Automatically cycles to balance chimney draft with burner ignition requirements.
- System Efficiency: Improves annual fuel utilization efficiency by curbing passive convection losses.
⚠️ Application Profile: Designed exclusively for commercial hydronic boiler installations including EGH-95 and EGH-105 models requiring automated flue management and energy conservation upgrades.
