ELECTRONIC IGNITION All (I) (IS) HRDV series furnaces are equipped with a solid state design, intermittent pilot ignition system. This electronic system consists of an ignition control module, combination pilot burner/igniter-sensor (sensor or flame rod) assembly, and igniter-sensor lead. Activated by the units 24V transformer and controlled by a field installed thermostat or controller, module will first perform a safe-start check which tests its internal components for a false pilot flame condition. - Page 19 d. Remove the screws from bottom flange of the collector box. Remove the two screws from the venter motor support at the right heater leg and disconnect the three conductor cables at the junction box. Lift collector box off. (Power venter assembly will remain attached to the collector box.) e.
