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 and reset the control.
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.
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.

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.
Please note that the brackets ([]) denote
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.
