120VAC Gas Ignition Controls
Reliable Ignition Control for Safe, Consistent System Operation
120VAC Gas Ignition Controls provide dependable ignition sequencing, flame monitoring, and safety shutdown for a wide range of gas-fired equipment. Designed to ensure safe startup and continuous operation, these controls manage the critical processes required to ignite and maintain a stable flame.
As part of the Fenwal Controls portfolio within the KiddeFenwal family of brands, 120VAC ignition controls are engineered for consistent performance, system safety, and long-term reliability across commercial and industrial applications.
The 120VAC Ignition Control Advantage
Integrated Safety and Control for Gas-Fired Systems
120VAC ignition controls manage the full ignition cycle, from initial spark generation to flame verification and system shutdown if unsafe conditions are detected. By continuously monitoring flame presence and system performance, these controls help prevent fuel buildup, misfires, and unsafe operation.
This integrated approach ensures that gas-fired equipment operates safely, efficiently, and in compliance with system requirements.
