Hot Surface Igniter products from Fenwal are carefully designed to safely control and deliver natural gas and LP in all types of commercial gas-fired appliances. Our Hot Surface Igniter has applications from rooftop heaters, water heaters, infrared burners and any other type of gas-fired appliance. When using our Hot Surface Igniter, flame sensing is achieved through the patented technique of using the hot surface element as the sensor or, if required a separate sensing probe may be employed. All models of the Fenwal Hot Surface Igniter utilize the principle of flame rectification to monitor the burner flame.

Our Hot Surface Igniter controls are available for 24VAC and 120VAC applications. CSA certified microprocessor circuit designs provide precise, repeatable timing sequences for ignition times and purge times (pre-, inter- and post-) as well as multiple tries for ignition. On-board diagnostics with LED output provides assistance with troubleshooting and ensures safe and efficient burner operation. Optional 120/240 VAC field selectable line voltage capability provides additional field-service efficiency and lowers inventory cost. Fenwal’s Hot Surface Igniter controls are not position sensitive and can be mounted vertically or horizontally using standard hardware. Three enclosure configurations available: Case and cover - dust and foreign object protection, Open board with stand-off's - saves space and cost, Potted - protection for washdown and extreme vibration.
