Safety Notes OWNERS MANUAL & MAINTENANCE Before using this meter, read all safety information carefully. In this manual the word “WARNING” is used to indicate conditions or actions that may pose physical hazards to the user. The word “CAUTION” is used to indicate conditions or actions that may damage this instrument. WARNING! This analyzer extracts combustion gases that may be toxic in relatively low concentrations. These gases are exhausted from the back of the instrument.
Finishing Up • Remove the probe from the flue and allow the analyzer to purge with fresh air until readings return to zero. - CO2 to 0.0%, CO to Zero (Be careful as the probe tip will be HOT) • Drain water trap • Check particle filter • Rotate selector to “OFF” NOTE: To protect the sensor “HIGH” will be displayed and the zero countdown will repeat until CO measured is less than 20 ppm.
General Maintenance • Check calibration of your instrument annually to ensure it meets original performance specifications • Keep your instrument dry. If it gets wet, wipe dry immediately. Liquids can degrade electronic circuits • Whenever practical, keep the instrument away from dust and dirt that can cause premature wear • Although your instrument is built to withstand the rigors of daily use, it can be damaged by severe impacts. Use reasonable caution when using and storing the meter.
Batteries Replacement This meter has been designed for use with alkaline batteries. No other types of batteries are recommended. The analyzer is supplied with 4 “AA” size alkaline batteries. These should be installed into the instrument as shown in the diagram to the right and indicated on the back of the unit. Note: Follow battery directions on back of housing Back of Instrument CAUTION! Battery Compartment Take great care when installing the batteries to observe correct polarity.
WHY TEST WITH THE C20 Verify Proper Operation Of Combustion Equipment • To verify that equipment is operating as the manufacturer designed it to work. This includes installation tests for CO2 and CO. - A properly tuned combustion appliance will perform better, and reduce the likelihood of call-backs for no-heat. • To verify that the maintenance work performed has corrected the problem. • To detect any defects early – possibly at installation.
WHAT RESULTS ARE GENERALLY ACCEPTABLE Atmospheric Gas Fired Burners • • • • CO2 .................................................................................... 7.0 to 8.0% CO2 Stack Temperature .......................................................... 325 to 500°F Draft (Water Column Inches)........................................... -.02 to -.04wc” Carbon Monoxide (parts per million) ............................. <100ppm Gas Fired Power Burners • • • • • CO2 .......................................
METER PROBLEM SOLVING If any problems are not solved with these solutions, contact us or an authorized repair center. Fault symptom Causes / Solutions CO or CO2 too low • Air leaking into probe, tubing, water trap or connectors. CO or CO2 reading (- - - -) • Meter was stored in a cold environment and is not at normal working temperature. Batteries not holding charge • Batteries exhausted. Meter does not respond to flue gas • Particle filter blocked. • Probe or tubing blocked.
GLOSSARY Selector and Display Parameters “ZeRO” Followed by decreasing numbers in the display during set-up CO (Carbon Monoxide) – Direct reading of the carbon dioxide sensor displayed in parts per million (ppm) COMAX Highest measured value of Carbon Monoxide since the instrument was powered on CO2 (Carbon Dioxide) – Direct reading of the carbon dioxide sensor displayed in percentage (%) BAT Displays the Battery power available. HIGH Displays at standby/power off if CO levels are greater than 20ppm.
