- Head air setting (oil line)
Boiler power setting: using a No. 4 hex head wrench, turn
the setting screw reference L, one way or the other
according to the setting desired.
- Internal air flow setting (regulator)
Boiler power setting: using a No.4 hex head wrench, turn
the setting button reference V, one way or the other
according to the setting desired. Notches on the button
and casing are for locking the button in position.
- Suction air setting (intake)
Boiler power setting: unscrew the reference U screws,
adjust the intake reference O to the desired graduation,
screw up the reference U screws.
6.3 Fitting the measuring instruments
- Fit a pressure gauge (0 to 15 bar) to the pump pressure
connector (reference K).
- Fit a vacuum gauge (-1 to 0 bar) to the pump vacuum
connector (reference M).
- Fit a U shaped pipe or sloping pipe (0 to 4 mbar) to the
head air pressure connector (reference C).
- Prepare the darkening index (ST), smoke temperature,
and CO2measuring equipment as well as the smoke
sampling hole in the smoke flue.
6.4 Air presetting (burner shut down)
Burners are delivered with the following settings that correspond
to the size of nozzle delivered and at 12 bar preset pump
pressure. Settings provided for boiler power of 75 kW.
6 START UP
6.1 Preliminary checks
- Check that the burner specifications are absolutely
equivalent to the fuel and boiler specifications.
- Check type of electric current available in the boiler room
(it shall be 230V » + earth).
- Check that the plant is full of water.
- Check oil level in the tank.
- Check that valves are open.
6.2 Pump starting
- Fill the pipes between the tank and burner either by
gravity if there is a filling “Tee”, or by starting the pump.
- Unscrew the pressure connector (reference K), insert a
flexible pipe and start the burner. When the fuel reaches
the pressure connector, stop the burner and screw up
the pressure connector. Avoid running the burner too
long without fuel in order not to damage the pump.
6.5 Oil pressure setting
- Switch on the burner. The programming unit indicator light (reference D) goes on, the fan starts (immediately if the burner
is “not reheated”) 50 seconds after switch on (if the burner is “reheated”). The burner ignites after 15 seconds of preliminary fanning.
- Using the setting screw (reference Q) set the fuel pressure by reading the value on the pressure gauge installed on the
pressure intake (reference K).
