Key Benefits: Reduced Off-Cycle Heat Loss: Seals the flue when the burner is idle to retain heat within the heat exchanger

though secondary fusing remains an industry best practice for additional circuit protection

1-1/2 HP industrial-grade motor designed for heavy-duty HVAC applications

Simplified Wiring: Designed for straightforward low-voltage connection to Selectra control systems

this switch prevents operation during flue blockage or draft inducer failure
