27. Press the ▲ arrow key until SET Valve
Position appears on the C-MORE display.
28. Press the CHANGE key. SET Valve Position
will begin to flash.
29. Press the ▼ arrow key until the SET Valve
Position reads 65% and press the ENTER
key.
30. Press the down ▼ arrow key until CAL
Voltage 65% is displayed.
31. Press the CHANGE key. CAL Voltage 65%
will begin to flash.
32. The oxygen level at the 65% 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
65% Valve Position
Oxygen %
± 0.2
Carbon
Monoxide NOx
6.3 % <50 ppm <30 ppm
33. 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.
34. Once the oxygen level is within the specified
range at 65%, press the ENTER key to store
the selected blower output voltage for the
65% valve position.
35. Press the ▲ arrow key until SET Valve
Position appears on the C-MORE display.
36. Press the CHANGE key. SET Valve Position
will begin to flash.
37. Press the ▼ arrow key until the SET Valve
Position reads 45%, then press the ENTER
key.
38. Press the ▼ arrow key until CAL Voltage
45% is displayed.
39. Press the CHANGE key. CAL Voltage 45%
will begin to flash.
40. The oxygen level at the 45% valve position
should be as shown. Also, ensure that the
carbon monoxide (CO) and nitrogen oxide
(NOx) readings do not exceed the values
shown.
Combustion Oxygen Level at
45% Valve Position
Oxygen %
± 0.2
Carbon
Monoxide NOx
6.5 % <50 ppm <30 ppm
41. 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.
42. Once the oxygen level is within the specified
range at 45%, press the ENTER key to store
the selected blower output voltage for the
45% valve position.
43. Press the ▲ arrow key until SET Valve
Position appears on the C-MORE display.
44. Press the CHANGE key. SET Valve Position
will begin to flash.
45. Press the ▼ arrow key until the SET Valve
Position reads 30%, then press the ENTER
key.
46. Press the ▼ arrow key until CAL Voltage
30% is displayed.
47. Press the CHANGE key. CAL Voltage 30%
will begin to flash.
48. The oxygen level at the 30% 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
30% Valve Position
Oxygen %
± 0.2
Carbon
Monoxide NOx
6.5 % <50 ppm <30 ppm
49. 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.
50. Once the oxygen level is within the specified
range at 30%, press the ENTER key to store
the selected blower output voltage for the
30% valve position.
