Commercial and industrial appliances with combustion chambers in excess of 400K BTU. Applications requiring CSD-1 certification.


The Series 35-67 is a hot surface ignition system in which the ignition source is proven to be capable of ignition prior to the gas valve being opened and is suitable for appliances over 400K BTU. Models compatible to the requirements of ASME standard CSD-1 are available.

The microprocessor circuit design provides precise, repeatable timing sequences for ignition times and purge times (pre-, inter-, and post-) as well as multiple tries for ignition. The control also continuously monitors the pressure switch, thermostat and main burner flame to ensure safe system operation. On-board diagnostics with LED output provide assistance with troubleshooting to ensure safe and efficient burner operation.
