Testing for Carbon Monoxide in Flues & Appliances
Note: It is recommended you perform routine general maintenance on your
analyzer to ensure proper function. Please refer to Appendix A for general
maintenance schedule and function tests.
1. Turn the 707 on in fresh air as outlined on page 8. After the initial purge
cycle the 707 will display the screen below.

Carbon Monoxide Display (Real Time)
• Displays Carbon Monoxide (CO) reading in parts per million
(ppm)
2. Connect the Mini Pump Protection Filter assembly and Flue Probe to the
Gas Sample Port. (See below & page 7)
IMPORTANT:
Prior to taking a sample, the device under test should be on and
at operating temperature.
Putting the flue probe in the sample area prior to
starting the device may cause saturation of the sensors due to the higher
initial concentration of carbon monoxide that may be encountered upon
start up.
If this happens, allow your analyzer to purge in fresh air until the
carbon monoxide level returns to 0 ppm. This may take more than an hour
depending on how saturated the sensors are.
