6.6 Taking Measurements - Buderus Logano GB125/22 BE Installation And Service Instructions Manual

6.6 Taking measurements
Allow burner to operate for 15 to 20 minutes before a
combustion test. Earlier combustion tests can lead to
incorrect readings as a result of burning off the sealant
rope. We recommend checking the burner after a few
weeks of operation.
Incorrect burner adjustment can cause con-
tamination of the boiler (e.g. soot). Faults may
occur more often than normal.
V Always check combustion with the follow-
ing instruments.
V Never adjust burner visually.
Required instruments:
– CO measuring equipment
2
– Draft measuring equipment
– Oil pressure gauge
– Stack thermometer
– Smoke tester
V Check the combustion chamber pressure at the pres-
sure testing port [1].
V Check the breeching draft at a test port in the vent con-
nector.
