Additional Features:
The Roberts-Gordon 90439500K Direct Spark Heater Ignition Control Module, manufactured by Fenwal, is an automatic ignition system designed to provide safe and reliable burner control for select Roberts-Gordon heating equipment, including BH The Economical Unitary Infrared Heaters, HED / CTH2D Gas-Fired Low Intensity Unitary Heaters, and Blackheat NP1 Negative Pressure Unitary or Multiburner Infrared Heaters. The module is housed in a compact gray rectangular enclosure. Functionally, the control executes a 45-second pre-purge, a 15-second ignition trial, and a 45-second interpurge, operating on a 24 VAC, 50/60 Hz input at 300 mA and driving a 24 VAC gas valve up to 2.0 A, ensuring proper combustion sequencing and safety shutdowns across a wide ambient range from -40°F to 160°F. The included ignition lead and the robust, clearly labeled design underscore its intended use as a durable, service-friendly control module that integrates seamlessly into the specified Roberts-Gordon heater platforms to manage ignition and flame safety with precision.
