Designed for Efficiency & Reliability

• Detailed heater status– Heater status information– Includes run history and diagnostics

• Power from the top down– A precise mixture of gas and forced

air for optimal combustion– Spiral shape of the coils keeps hot

gases swirling along the walls of the tank, using centrifugal force to achieve an extremely high rate of heat transfer and thermal efficiency of up to 95%

– Quiet operation

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

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

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

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

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

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

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.
