10 Start-up(continued)

Check flame and combustion (continued)

4.Place the water heater into the active position by pressing the RIGHT SELECT [ON] key (FIG. 11-1, page 63).

5.Locate the pinhole button below the RESET button on the display board (FIG. 11-1). Insert a thin wire (such as a paper clip) into the hole and press the button once and hold for 5 seconds to place the water heater into Service Mode. In Service Mode the water heater will fire at ignition speed and will then modulate up to full fire.

6.Insert the probe from a combustion analyzer into the hole left by the removal of the flue temperature sensor.

7.Once the water heater has modulated up to full fire, measure the combustion. The values should be in the range listed in Table 10A below. The CO levels should be less than 150 ppm for a properly installed unit.

If the combustion is not within the specified range, reference the Troubleshooting Section of the Armor Water Heater Service Manual for possible causes and corrective actions.

8.Once the combustion analysis is complete, test the safety shutoff device by turning the manual shutoff valve to the OFF position and ensuring that the water heater shuts down and registers an alarm. Open the manual shutoff valve, reset the control, and return to Service Mode.

9.Turn the main power off to the water heater and replace the flue temperature sensor into the flue pipe connection.

10.Place the water heater back into normal operation.

￿ WARNING

You must replace the flue gas temperature

 

sensor to prevent flue gas spillage into

 

the room. Failure to comply could

 

result in severe personal injury, death, or

 

substantial property damage.

screen status.

 

The NAVIGATION dial may be used during normal operation to adjust the tank set point temperature.

1.From the Status Screen press the NAVIGATION dial.

2.Press the NAVIGATION dial then rotate the NAVIGATION dial to adjust the temperature.

3.Once the desired temperature is displayed, press the RIGHT SELECT [SAVE] key.

4.Press the RIGHT SELECT [HOME] key to upload the changes.

5.If the RIGHT SELECT [SAVE] key is not pressed, the new settings will be discarded.

Verify WHR circulator mode

When the tank thermostat or tank sensor calls for heat, the SMART SYSTEM control will turn on the water heater pump. When the DHW call for heat ends, the water heater pump will continue to run for a period of time. This pump delay is set at the factory to 60 seconds. If a shorter or longer delay is desired, the appropriate parameter in the control must be changed. See the Armor Water Heater Service Manual for a detailed explanation of this procedure.
