The 37E73A series INTELLI-VENTTM control is a combination gas valve, ignition control, and thermostat for use on Power Vented water heaters. The microcomputer in the control supervises the ignition sequence and timings for the water heater, and provides diagnostic codes in case of system malfunction. The control provides direct burner ignition using the White-Rodgers’ Silicon Nitride Ignitor (the 21D64-2). The control uses the INTELLI-VENTTM technology to greatly extend the ignitor’s life.
