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
7
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
8
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

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

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.
12
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
13
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.
14
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.
