Combustion Oxygen Level At 45% Valve Position; Combustion Oxygen Level At 30% Valve Position; Combustion Oxygen Level At 18% Valve Position; Combustion Calibration - Aerco Benchmark 2.0 Installation, Operation & Maintenance Instructions Manual

Combustion Oxygen Level at
45% Valve Position
Oxygen % Carbon
± 0.2 Monoxide
7.2 % <50 ppm
40. 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.
41. 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.
42. Press the ▲ arrow key until SET Valve

44. Press the ▼ arrow key until the SET Valve
Position reads 30%, then press the ENTER
key.
45. Press the ▼ arrow key until CAL Voltage
30% is displayed.
46. Press the CHANGE key. CAL Voltage 30%
will begin to flash.
47. 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 % Carbon

8.0 % <50 ppm
48. 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.
49. Once the oxygen level is within the specified
range at 30%, press the ENTER key to store
the selected blower output voltage for 30%
