Product Description P/N: G67AG-3
Description
The Johnson Controls G67AG-3 is an intermittent pilot ignition control for compatible gas-fired heating equipment. It uses high-voltage spark ignition to light the pilot and permits main burner operation after the pilot flame is detected.

Information About G67AG-3
The G67AG-3 is a self-checking model in the Johnson Controls G67 ignition control family. Its solid-state circuitry integrates spark generation, flame monitoring, and pilot and main gas valve control. It operates with a compatible thermostat, pilot burner, flame sensor, and redundant main gas valve arrangement. The control uses flame rectification to verify combustion and responds to flame loss by de-energizing the main valve and restarting the ignition sequence.
Key Features:
- Intermittent pilot operation: Energizes the pilot during a heating demand and shuts it off when the demand ends.
- Spark ignition: Uses capacitive-discharge high-voltage spark to ignite the pilot burner.
- Flame verification: Uses flame rectification before permitting main gas valve operation.
- Flame-loss response: De-energizes the main valve within a maximum of 0.8 second after loss of proven flame.
- Continuous ignition trial: Continues attempting pilot ignition while the thermostat calls for heat.
- Low-voltage supply: Operates from nominal 24 VAC power at 50/60 Hz.
- Ambient capability: Supports operating temperatures from −40 to 150°F.
- Specified spark gap: Uses a nominal electrode gap of 0.1 inch.
The G67AG-3 delivers the reliability and precision required for coordinated pilot ignition and flame supervision in compatible gas heating systems.
