6.6 Notes on commissioning the burner
Allow burner to operate for 15 to 20 minutes before per-
forming a combustion test. Earlier combustion tests can
lead to incorrect readings as a result of burning off the
sealing rope. We recommend rechecking the burner after
a few weeks of operation.
Required instruments:
–CO
2
measuring equipment
– Draft measuring equipment
– Oil pressure gauge
– Stack thermometer
–Smoke tester
V Check the combustion chamber pressure at the test
port.
V Check the breeching draft at a test port drilled in the
vent connector (chimney vent models only).

6.7 Raising flue gas temperature
For the set flue gas temperature for the boiler see the
technical data (Æ Chapter 2.7, page 8).
You may raise the flue gas temperature if you discover
during tests that the flue gas temperature is too low for
the type of chimney used (risk of condensation) by one or
several of the following measures:
Incorrect burner adjustment can cause con-
tamination of the boiler (e.g. soot), leading to
low efficiency, high emissions, and a greater
risk of service calls.
V Always check combustion with the follow-
ing instruments.
V Never adjust burner visually.
