4.6 DRAFT / PRESSURE MEASUREMENT IN
FLUE GAS MEASUREMENT
The BluFlame can be used to measure the draft in the flue pipe at the probe
tip’s location. This draft measurement is independent of the actual upstream
or downstream flue gas measurement.
• Tap the context menu button.
• Tap “Draft/Press.”
During this measurement, the measuring gas pump will not suck in any gas,
and the gas value measurement will stop.
The “Draft/Press.” reading screen will show the current pressure reading.
This value can be used for the draft or pressure measurement. The difference
between these two parameters is simply their name and their sign. Within
this context, a vacuum in the flue will be stored as a positive reading.
The pressure sensor used for the draft measurement must be
zeroed while in the measuring position.
• Tap the Back button.
✔ The BluFlame will switch to the flue gas measurement, and the transferred
