FRESH AIR PURGE

Each time the analyzer is turned on it will perform a 60 second air purge, this is to clear 

the gas sampling path (including probe, if connected), and self calibrate the CO

detection system. For these reasons it is very important that the analyzer be in 

outside 

fresh air 

when powered on.

QUICK START

Turn on the analyzer by pressing the On/Off Button for 2 seconds until the unit activates. As described the analyzer will perform a 60 

second turn on purge. Once completed simply select the reading desired by the position of the rotary dial.

MEASURING FLUE GASES

After the initial countdown is finished and the analyzer is properly setup, put its’ flue probe in the appliance’s sampling point. The tip of 

the probe should be at the center of the flue. Use the flue probes depth stop cone to set the position.

With balanced flues, make sure the probe is positioned into the flue so no air can “back flush” into the probe.

NOTE: 

Ensure the flue probe handle does not get hot!
