5 Commissioning and operation
5.1 Safety notes on initial commissioning
The initial commissioning must only be carried out by the
supplier, manufacturer or their appointed agent. At this
time, all the control and safety equipment must be
checked to ensure correct operation and, if it can be
adjusted, it should be checked that it has been set
correctly.
Furthermore the correct fusing of the circuits and the
measures for contact protection of electrical equipment
and of all wiring must be checked.
5.2 Preparations for initial commissioning
Venting the suction line
The suction line must be fully filled with oil and
vented prior to the initial commissioning. Oth-
erwise, the pump can become seized as a re-
sult of running dry.
☞
Vent by hand using a suction pump.
Connect
➀
manometer
For measuring the fan pressure into the mixing head whilst
the burner is being adjusted.
Connect ammeter
➁
To measure sensor current during setting (use test adaptor
No. 13; order No. 240 050 12 04/2).
Response limit for extraneous light: _____________ <15µA
Response limit for operation: __________________ >30µA
Recommended sensor current range: _______ 40 - 100µA
Max. achievable sensor current: _____________ ca. 120µA
Connect a pressure gauge to the oil pump
1. Connect pressure gauge (see Ch. 3.2).
2. Connect vacuum gauge (see Ch. 3.2).
ATTENTION
Connect instruments

Checklist for initial commissioning
❏
The heating appliance must be assembled ready for
operation.
❏
The operating instructions of the heat exchanger must
be followed.
❏
The whole plant must be wired correctly.
❏
The heating appliance and the heating system must
be sufficiently filled with heating medium.
❏
Flues must be free from obstructions.
❏
The ventilators on air heaters must work correctly.
❏
Sufficient fresh air must be available.
❏
The required test points for combustion analysis must
be available.
❏
Ensure soundness of the heat exchanger and the flue
gas section up to the test point to avoid extraneous air
from falsifying the test results.
❏
Water level controls must be set correctly.
❏
Thermostat, pressure switch and other safety devices
must be in operating position.
❏
There must be a heat demand.
❏
Fuel lines must be purged of air.
❑
The correct nozzle must be selected and fitted
correctly (see Ch. 4.7)
❑
The distance between the diffuser and nozzle must be
set correctly (see Ch. 7.5).
❑
Ignition electrodes must be set correctly (see Ch.
7.4).
Note
Dependent on site requirements, further
checks may be necessary. Note the
instructions for the individual items of plant
equipment.
Pressure gauge on the oil pump (for commissioning)
Refit closing plug
once measurement
has been taken.
