Introduction

emission levels in the stack gas and then display measured and calculated values on its LCD. Values are listed in Section 2 Specifications.

During a test, the COLow sensor is protected from high CO levels by being automatically flushed with fresh air when the detected CO level exceeds 4,000 ppm. The analyzer will automatically start using its optional CO- High sensor, if installed, at CO levels starting at 4,001 ppm, thus providing continuous CO readings up to 20,000 ppm.

A backlight enables a user to read the display in dimly-lit areas. Turn the backlight ON and OFF by briefly pressing the I/O button.

The analyzer is turned OFF by pressing and holding down the I/O button for at least 2 seconds. Note that there is a 5-second delay before the analyz- er actually turns OFF, during which time the analyzer can be turned back ON by pressing the run/hold button. In addition, there is a gas-purge feature that keeps the analyzer’s pump running if the gas level inside the sensor chambers is abnormally high at shutdown. With the probe removed from the stack and sampling fresh air, the analyzer purges itself until the detected gas concentrations drop below predetermined levels.

1.5 Connector Descriptions

1.5.1 Probe Connections (Gas, Pressure, T-Stack)

Attach the probe and hose assembly to the analyzer by connecting its . . .

•stack-gas thermocouple to the analyzer's T-STACK connector,

•stack-gas hose to the analyzer's GAS connector,

•draft hose to the analyzer's +∆P connector.

Observe that the probe connectors are of different sizes and shapes, which prevent incorrect connection to their associated connectors on the analyzer.

1.5.2 T-AIR (Primary Air Thermocouple)

If thermocouple P/N 104-1797 (10 feet long) or Utility Wand P/N 104-1799 (12 inch ridged probe with handle and 5 foot coiled cable) is to be used to measure the burner’s primary air temperature, then connect either of these thermocouples to the analyzer’s T-AIR connector.
