The Intelli-Vent 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 Silicone Nitride Ignitor. The control uses INTELL-IGNITION technology to greatly extend the ignitor's life.

Fixed Adjustment Regulator Controls: The gas regulator on this control requires no field service. The regulator automatically controls and maintains the burner gas pressure.
