Safety Information Only qualified personnel trained in service and installation of electric heaters, boilers, and furnaces shall use this combustion analyzer. This device measures and analyzes key parameters of combustion equipment including oxygen, carbon monoxide, temperature, carbon dioxide, efficiency, and draft pressure. Read and understand this operator’s manual in its entirety before using to prevent injury or damage to you or the equipment.
Description The Fieldpiece CAT85 Combustion Analyzer HC provides a hassle-free solution for technicians to get the job done quickly, easily, and safely while improving system efficiency. Accurate sensors of O2, CO, pressure, and temperature along with powerful trending, provide key insight into equipment performance. SensorVault™ technology seals to prolong sensor life. Live draft pressure measurement maintains accuracy throughout your combustion test.

Common Sampling Points SP The many types of combustion equipment vary in their design and therefore their ideal sampling points. However, there are commonalities that make forSPuseful guidelines when analyzing performance. Heed equipment manufacturer instructions SP above anything mentioned in this manual. • • • Before inserting the probe in the flue, it’s good practice to test for excessive soot which may lead to carbon buildup within the analyzer or overexpose sensors.
Operation The CAT85 workflow is streamlined to quickly get into your job, complete your testing, send your report, and get onto your next job. SensorVault™ Technology The SensorVault™ technology of the power button unseals sensors when powering on and and seals the sensors when powering off. This requires a bit more force than most other buttons so be sure to press fully. You’ll hear a “click”. Powering ON Read “Safety Information” section. 1. Push the probe cable connector into the bottom of CAT85. 2.
Job Menu The JOB MENU is the heart of CAT85. Each job has its own list of saved tests. After saving your tests, view directly in the Job Link® mobile app or send your report to a model CATPR wireless thermal printer. SAVE AND EXIT when you’re ready for your next job. Jobs are automatically numbered sequentially. Open the JOB ARCHIVE to view, continue, or delete jobs. Combustion By default, the COMBUSTION test starts automatically after startup is complete.
Ambient CO CO is a very dangerous gas and it’s critical that living spaces are clear of carbon monoxide. Read “Safety Information” section. 1. Ensure startup is complete. See “Powering On” section. 2. Select AMBIENT CO from the JOB MENU. 3. View CO measurement while walking through the living space. 4. SAVE the measurement displayed. “DELETE” temporarily deletes a single value so you can retest. “DELETE TEST” deletes the test.
Primary Air Primary air temperature is measured during startup and is used for the COMBUSTION test. This is the temperature of the air going into the combustion equipment. It’s sometimes useful to set it after startup if the ambient temperature changes. You can enter it manually or use the probe’s temperature sensor. Read “Safety Information” section. 1. Ensure startup is complete. See “Powering On” section. 2. Select PRIMARY AIR from the JOB MENU. 3.
Manometer The manometer test uses P1 and P2 ports for easy static pressure testing. Save P1-P2 simultaneously or separately. Read “Safety Information” section. 1. Ensure startup is complete. See “Powering On” section. 2. Mount the CAT85 onto a secure, cool, magnetic surface near the test point(s). 3. Connect static pressure hose (not included) to P1. Connect static pressure hose (not included) to P2. 4. Select MANOMETER from the JOB MENU. 5.
Report Each job has a report which is a collection of saved tests, your company info, reference O2, date, and time. Date and time is recorded at the time of sending the report. Edit report contents from settings. 1. 2. 3. 4. 5. Ensure startup is complete. See “Powering On” section. Select REPORT from the JOB MENU. At least one test must be saved to view the job report. Access the JOB MENU of saved jobs from JOB ARCHIVE. Scroll through the report using the scroll bar.
Settings Access SETTINGS from the top right corner of the Job Menu. Each setting button cycles through its options or to its own screen (blue arrow). The DEFAULTS button in the top right corner of the settings reverts to default settings, but jobs are not deleted. Job Link® System: OFF (default), ON Select ON to view live combustion and saved tests on the Job Link system mobile app. (Affects battery life.) Brightness: HIGH, MEDIUM (default), LOW (Affects battery life.
Maintenance General Wipe with damp cloth to clean the exterior. Do not use solvents. Dust Filter Replacement Replace the dust (particulate) filter if you notice slow response times or when it’s visually darker. Dust Filters: model RFC10 1. 2. 3. 4. 5. Ensure the probe has cooled before opening to avoid contact with hot gas and liquid that may be within the probe. Rotate the Filter Cap 1/4 turn counter-clockwise to release. Pull out the old Probe Filter and replace if needed.
Sensor Replacement SensorVault™ technology prolongs the life of sensors, but they eventually need to be replaced. When a sensor’s life drops below 5%, a notification appears during startup to inform you it’s time to replace it. You can view estimated remaining life at any time in SETTINGS. O2 sensor: model RSO2L CO sensor: model RSCOR Carbon Monoxide Sensor (RSCOR) Sensor Cover 1. 2. 3. 4. 5. 6. 7. 8. 9. 2.5mm Hex Sockets 28 Oxygen Sensor (RSO2L) Double check which sensor needs to be replaced.
