CHECKS BEFORE COMMISSIONING:
• That the burner is assembled in
accordance with the instructions given
here.
• Setting the combustion components.
• All electrical connections must be correct.
• Check the burner motor for correct
direction of rotation.
• The heat generator must be ready for
operation, and the operating regulations
for the heat generator must be observed.
• The heat generator and heating system
must be filled with water and the
circulating pumps must be in operation.
• The temperature regulator, pressure
regulator, low water detectors and any
other safety or limiting devices that might
be fitted must be connected and
operational.
• The exhaust gas duct must be
unobstructed and the secondary air
system, if available, must be operational.
• An adequate supply of fresh air must be
guaranteed.
• Check tank, lines and oil pump are filled
with oil and correct oil nozzle is fitted.
• With burner in starting position check that
air damper is in “CLOSED” position.
• Check that control box is unlocked and in
its original position.
• A standard-compliant measuring point
must be available, the exhaust gas duct up
to the measuring point must be free of
leaks to prevent anomalies in the
measurement results.
OIL START-UP
Open all shut-off valves of oil supply
system.
• Set fuel selector switch to its “Oil”
position.
• Fill pump with oil.
• Mount pressure gauge in the feed line
and return line.
• Mount the pressure gauge for checking
the pump suction pressure.
• Make sure that the nozzle is size and
mounted correctly.
Bleeding of oil system
Shortly start the burner and check for
proper direction of rotation. Bleed the oil
line and oil pump.
CAUTION:
The hydraulic system has been
filled with oil by the manufacturer.
This may cause ignition trouble when
initially operating the system.
When starting the burner take care to
increase the oil pressure slowly to the
operating level.
Prior to the initial fuel feed start make
a functional test of the burner program
flow:
Oil system:
• Open all shut-off valves of the oil supply
system.
• The oil solenoid valve in the feed line
disconnect on the terminal strip (see
Circuit Diagram).
• Start burner and check program flow for
correct start-up sequence:
1. Fan starts.
2. Pre-ventilating damper.
3. Air pressure check.
4. Partial-load air damper.
5. Ignition.
6. Valves open (disconnected valve
remains closed).
7. Safety lock-out after expiry of safety
period (see control box).
• Reconnect the valve.
• Unlock the control box.
