Critical Factors to Consider Before Using a Flue Gas Analyser

All heating professionals are much as the part of the process of combustion analysis – from setting up the digital flue gas analyser, using it and interpreting combustion results for safety and maximum efficiency of a heating appliance. However, heating professionals must always consider other critical factors affecting the analysis equipment regardless of whether or not it is in use.

Listed below are some of those critical factors:

• Get to know the flue gas analyser. Study the product manual to thoroughly familiarise yourself with the flue gas analyser functions and any peripherals (printers etc.) before using it.
• Ensure any rechargeable batteries within the equipment are fully charged before arriving at the service site.
• Ensure that any mains power supply is undamaged and ready for use before arriving at the service site.
• Check to see if any printer has sufficient paper before arriving at the service site.
• Never expose the equipment to moisture, fuel oils and chemicals as this may seriously affect the operation of the flue gas analyser.
• Ensure that the correct fuel type is selected on the flue gas analyser for the type of fuel used.
• Avoid using the flue gas flue analyser for long periods or during freezing temperatures, as this may limit the life of the internal sensors.
• Use the equipments backlit display facility during poor lighting conditions to avoid inaccurate readouts.
• Ensure that any condensation (water) trap is frequently emptied to maintain optimum performance and to help prevent equipment damage.
• Try to avoid leaving the flue gas analyser unattended when in use to help prevent any external interference.
• Clean the heating appliance, its components and the immediate service area first before using the flue gas analyser.
• Always perform a smoke test on oil-fired heating appliances before using a flue gas analyser to prevent damage to the equipment’s internal sensors.
• Avoid kinking or damaging sensor tubes, probes and thermocouples, as this will severely compromise the operation of the flue gas analyser.
• If fitted, always leave the flue gas analyser within its protective boot jacket when in use.
• Never use the analysis equipment and/or its probes on or near live electrical components.
• The flue gas analyser should be stored securely in its carry case when transporting to and from the service site and when not in use.
• When in use, attach the flue gas analyser to the heating appliance casing using its magnetic boot jacket to keep it out of harms way when making adjustments to burners etc.
• Always follow manufacturers instructions and recommendations for servicing and maintenance of the flue gas analyser.
