Fenwal 35-725200-505 Control

The Fenwal 35-725200-505 is a robust 120 VAC direct spark ignition control engineered for high-demand gas-fired applications, including commercial cooking equipment, infrared burners, and construction heaters. Utilizing advanced microprocessor technology, this ignition module delivers precise and repeatable timing sequences for pre-purge, inter-purge, and ignition trials. This specific model is potted to ensure maximum protection against washdown, high humidity, and extreme vibration, making it a reliable choice for harsh mechanical environments.

Featuring a Potted Single Spark & Sense configuration with a 10-second trial for ignition (10 TFI), the 35-725200-505 simplifies installation with its multi-pin connector and integrated flame sensing. The DETECT-A-FLAME® technology ensures a safe start by verifying flame presence before allowing the gas valve to remain energized. As a veteran-grade HVAC replacement part, this 120V control is compatible with natural, LP, and manufactured gases, operating effectively in temperatures ranging from -40°F to 175°F. Its line polarity insensitive design reduces the risk of miswiring, ensuring a clean and efficient install for field technicians.

Key Benefits
  • Precision Microprocessor Control: Eliminates timing drift and ensures consistent burner sequencing across all cycles.
  • Environmental Durability: The potted enclosure prevents moisture ingress and protects internal components from vibration-induced failure.
  • DETECT-A-FLAME® Safety: Integrated flame sensing provides immediate lockout if a flame is not detected, protecting the heat exchanger and burner assembly.
  • Simplified Wiring: Features a multi-pin connector for fast field replacement and reduced labor time.
  • Versatile Application: Suitable for a wide range of 120 VAC gas burner systems up to 400K BTU.
Common Questions

How do I reset the control after a lockout?
Lockout recovery is achieved by cycling the thermostat or removing 120 VAC power for at least five seconds.

What is the difference between local and remote flame sensing on this unit?
The 35-725200-505 utilizes single spark and sense (local sense), meaning the spark igniter and flame sensor are the same component, reducing the total number of electrodes needed in the burner box.

Can this module be used in washdown environments?
Yes, the potted construction is specifically designed for applications where moisture exposure or heavy vibration is expected, providing superior protection over open-board alternatives.
