Ambient CO Warning
Vacate the area immediatly if you see the Ambient CO warning. It
appears if the CO sensor detects a harmful level of CO. The CO warning
level can be adjusted from the warning screen.
Drafts
CAT45 does not measure draft pressure with the COMBUSTION test,
but a saved FLUE DRAFT measurement shows during COMBUSTION.
Draft pressure measurement is important for safety and performance.
Read “Safety Information” section.
1. Ensure startup is complete.
See “Powering On” section.
2. Select DRAFTS from the JOB MENU.
3. Mount the CAT45 onto a secure, cool, magnetic surface near the
sampling point.
4. ZERO PROBE to zero the probe’s pressure sensor.
Always remove the probe from the flue before using ZERO PROBE.
5. Move probe to desired sampling point- DILUTED, FLUE, or
OVERFIRE.
6. View live measurement.
7. SAVE the measurement displayed.
“DELETE” temporarily deletes a single value so you can retest.
“DELETE TEST” deletes the test.
8. Remove the probe from the sampling point when finished.
Be careful not to let the metal touch anything until it cools.
