BOILER START-UP
6.1.
Initial lighting checks
Before you start the boiler, make the following checks:
Check that all the hydraulic connections and make sure they are tight. Make sure there is
no leakage or moisture on the pipes or other equipment.
Make sure that the connection with the chimney is air-tight and the chimney installation is
properly made.
Check that the controller bulbs are well inserted and secured in the boiler’s case.
Make sure that the pressure in the network is correct.
Check that the boiler pump and the central heating pumps function properly.
Make sure that the connection with the expansion vessel is correct and the expansion
volume is sufficient for the boiler. No valves should be installed between the boiler and the
expansion vessel.
Make sure the boiler’s separation valves are open.
Make sure that there is sufficient air supply and natural ventilation in the boiler room.
Do not store inflammable materials or fuel close to the boiler! Before you light
the boiler make sure the boiler room is clear and safe.

Start-up
To correctly start up the BIOPLEX boiler follow the next steps:
Make sure the silo is full with fuel.
Make sure the chimney damper is positioned in horizontal position (completely open).
Open the middle door (feeding door) to have visual supervision of the feeding procedure.
Turn the control panel on from the general switch and activate only the motor from the
corresponding switch. Keep the fan deactivated during this step.
Set the first timer T1 to maximum and the second T2 to zero, in order to fill the furnace
with fuel. Fill it until the fuel level reaches the cast iron plate and covers a small part of it.
Stop the motor function from the motor switch.
Using sheets of thin paper or other ignition material, light the fuel placed in the furnace.
Wait several minutes until the flame stabilizes and covers the entire plate surface.
Close the middle door of the boiler. Turn on the fan by the corresponding switch. During this
step the motor must remain deactivated.
When the flame is fully developed, activate both the motor and the fan. Set the furnace
thermostat to the required temperature.
Follow the instructions given in the chapter Combustion Regulation to correctly regulate the
combustion.
It is prohibited to light the boiler with inflammable or explosive liquids.

Checks to carry after initial start-up
During the first start-up you need to carefully check the air-tightness of all the connections,
especially the doors and the connection with the chimney.
Check that the thermostats function properly and devices operate accordingly. Wait for the
boiler to reach the preset temperature and make sure the fan stops properly and the flame
falls down.
Check the temperature and pressure rise in the network. Make sure it is according to the
indications. Check if there is any water leakage in the network.
After burning of the fuel is completed, check the situation inside the boiler. If the walls are too
black, it means that there is insufficient air supply. If there is condensation forming on the
