7. 7 Advanced Control System Intelligent Electronic Control Panel Provides precise temperature control and unit operating information Large backlit LCD display gives current operation mode, temperature and operating set point Self-diagnostics with plain English display –Easy to navigate menu

8. 8 Advanced Control System How it makes service and repair easier: Control monitors the powered anodes and automatically adjusts the anode protection depending on the water conditions If the control senses an anode system malfunction, it alerts the user of the situation, allowing them to have the tank inspected and avoiding an emergency leak Provides detailed heater status information: blower, igniter, igniter current, gas valve, flame detection, air inlet restrictions, exhaust vent restrictions, acceptable gas supply pressure Precise temperature setting with actual tank temperature at upper and lower probes

9. 9 Advanced Control System How it makes service and repair easier: Maintains a constant log of the number of cycles and burner operating time Monitors and reports on 32 different potential operating faults Communicates the details of the fault and gives diagnostic information Maintains a log of any fault occurrence and the time a fault occurred If service is ever required, the control alerts the user of the fault and provides plain English diagnostics to assist in correcting the issue

10. 10 High Efficiency Combustion System The HCG Series burner and blower system provides dual benefits: –Added efficiency –Ultra quiet operation

11. 11 Powered Anode System Provides longer-lasting tank protection Titanium Electrodes Connecting Wires Anode Control Perforated Sleeves Perforated Plastic Sleeve Titanium Electrode

12. 12 Powered Anode System What benefits does it offer? The American powered anode system provides reliable tank protection. Traditional sacrificial anodes are designed to be consumed over time, eventually leaving the tank unprotected and leading to tank failure. However, the reliable American powered anodes uses the most modern technology available to provide long lasting tank protection. No Anode Maintenance or Inspection = Years of reliable operation Powered anodes eliminate the potential for smelly water. Proven Reliability – Powered anodes have been used for years in Europe and on a limited basis in the United States with excellent results.

13. 13 Powered Anode System How does it work? The powered anode system consists of two main components: –Potentiostat built into the intelligent control –Titanium anode probe

14. 14 Powered Anode System The potentiostat measures conditions in the tank. Based on this information, the control calculates the precise current required to meet the reference potential. This exact amount of current is then fed to the titanium anode located in the tank in order to achieve the optimum protection level. These measurements and supply cycles alternate at millisecond intervals. Over time (or as water conditions change), the amount of power needed to protect the tank is adjusted. In the event of a powered anode malfunction or failure, the intelligent control will flash an alert or explanation.

15. 15 Flexible Venting Power-vent and power direct-vent provides uncontaminated air to be pulled directly into the unit with the flue gas products being expelled directly through the wall to the outside. Sealed Direct-vent Vertical Sealed Direct-vent Sidewall Indoor Conventional Vertical Indoor Conventional Sidewall 4” Vent 120’ Intake 120’ Exhaust 3” Vent 50’ Intake 50’ Exhaust 3” Vent 50’ Intake 50’ Exhaust 4” Vent 120’ Intake 120’ Exhaust 4” Vent 120’ Exhaust 3” Vent 50’ Exhaust 4” Vent 120’ Exhaust 3” Vent 50’ Exhaust
