AERCO BMK 3.0 LN Dual-Fuel Series Gas Fired Low NOx Boiler System - Manual (Page 40)

INITIAL START-UP
4-8
Combustion Oxygen Level at
60% Valve Position
Oxygen %
± 0.2
Carbon
Monoxide NOx
5.5 % <150 ppm <100 ppm
26. 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.
27. Once the oxygen level is within the specified
range at 60%, press the ENTER key to store
the selected blower output voltage for 60%
valve position
NOTE
The remaining steps basically repeat the
procedures in steps 20 through 27 for
valve positions of 45%, 30% and 18%.
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.
28. Press the ▲ arrow key until SET Valve
Position appears on the C-MORE display.
29. Press the CHANGE key. SET Valve Position
will begin to flash.
30. Press the ▼ arrow key until the SET Valve
Position reads 45% and press the ENTER
key.
31. Press the down ▼ arrow key until CAL
Voltage 45% is displayed.
32. Press the CHANGE key. CAL Voltage 45%
will begin to flash.
33. 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.
Combustion Oxygen Level at
45% Valve Position
Oxygen %

Carbon
Monoxide NOx
5.2 % <100 ppm <100 ppm
34. 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.
35. 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.
36. Press the ▲ arrow key until SET Valve
Position appears on the C-MORE display.
37. Press the CHANGE key. SET Valve Position
will begin to flash.
38. Press the ▼ arrow key until the SET Valve
Position reads 30%, then press the ENTER
key.
39. Press the ▼ arrow key until CAL Voltage
30% is displayed.
40. Press the CHANGE key. CAL Voltage 30%
will begin to flash.
41. 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
6.0 % <100 ppm <100 ppm
42. 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.
43. 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.
44. Press the ▲ arrow key until SET Valve
Position appears on the C-MORE display.
45. Press the CHANGE key. SET Valve Position
will begin to flash.
46. Press the ▼ arrow key until the SET Valve
Position reads 18%, then press the ENTER
key.
