it prevents heat exchanger damage and hazardous conditions by interrupting the burner circuit if the plenum temperature exceeds specified tolerances

Stainless Steel Power Element: Enhances durability and corrosion resistance in harsh mechanical environments

Unlike ice cube relays that require separate bases

This VT3417 model ensures quiet operation even at high flow rates and is a direct replacement for existing PopTop applications

Precision Control: High-leverage valve linkage ensures stable regulation from maximum individual loads down to tiny pilot flows

Fenwal 35-605601-201 Control Refrigerant it prevents heat exchanger damageThe Fenwal 35 605601 201 is a high performance 24V Direct Spark Ignition (DSI) control module engineered for precise burner sequencing in gas fired heating systems. This microprocessor based unit utilizes standard 24 VAC input and features a fixed 30 second pre purge period followed by a 4 second trial for ignition (TFI) to ensure safe and efficient combustion. Designed for reliability in the field, it includes on board LED diagnostics for rapid
