INITIAL START-UP

19. Press the CHANGE key. SET Valve Position

will begin to flash.

20. Press the ▲ arrow key until the SET Valve

Position

reads 80%. Press the ENTER key.

21. Next, press the

down (▼) arrow key until

CAL Voltage 80%

is displayed.

22. Press the CHANGE key and observe that

CAL Voltage 80%

is flashing.

23. The oxygen level at the 80% valve position

should be as shown below. Also, ensure that
the carbon monoxide (CO) and nitrogen
oxide (NOx) readings do not exceed the
values shown.

Combustion Oxygen Level at

80% Valve Position

Oxygen %

<30 ppm

24. If the oxygen level is not within the specified

range, adjust the level using the ▲ and ▼
arrow keys. This will adjust the output
voltage to the blower motor as indicated on
the display. Pressing the ▲ arrow key
increases the oxygen level and pressing the
down ▼ arrow key decreases the oxygen
level.

25. Once the oxygen level is within the specified

range at 80%, press the ENTER key to store
the selected blower output voltage for the
80% valve position.

NOTE

The remaining steps basically repeat the
procedures in steps 18 through 25 for
valve positions of 60%, 45%, 30% and
16%. However, since oxygen levels vary,
these steps are repeated in their entirety.
When performing these steps, also
ensure that the carbon monoxide (CO)
and nitrogen oxide (NOx) readings do not
exceed the values shown for each valve
position.

26. Press the ▲ arrow key until SET Valve

Position

appears on the C-MORE display.

27. Press the CHANGE key. SET Valve Position

will begin to flash.

28. Press the ▼ arrow key until the SET Valve

Position

reads 60% and press the ENTER

key.

29. Press the

down ▼ arrow key until CAL

Voltage 60%

is displayed.

30. Press the CHANGE key. CAL Voltage 60%

will begin to flash.

31. The oxygen level at the 60% valve position

should be as shown below. Also, ensure that
the carbon monoxide (CO) and nitrogen
oxide (NOx) readings do not exceed the
values shown.

32. If the oxygen level is not within the specified

range, adjust the level using the ▲ and ▼
arrow keys. This will adjust the output
voltage to the blower motor as indicated on
the display. Pressing the ▲ arrow key
increases the oxygen level and pressing the
▼ arrow key decreases the oxygen level.

33. Once the oxygen level is within the specified

range at 60%, press the ENTER key to store
the selected blower output voltage for the
60% valve position.

34. Press the ▲ arrow key until SET Valve

Position

appears on the C-MORE display.

35. Press the CHANGE key. SET Valve Position

will begin to flash.

36. Press the ▼ arrow key until the SET Valve

Position

reads 45%, then press the ENTER

key.

37. Press the

▼ arrow key until CAL Voltage

45%

is displayed.

38. Press the CHANGE key. CAL Voltage 45%

will begin to flash.

39. The oxygen level at the 45% valve position

should be as shown below. Also, ensure that
the carbon monoxide (CO) and nitrogen
oxide (NOx) readings do not exceed the
values shown.
