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.
▪
C
heck 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.

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 burner 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 a burning cycle 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
boiler walls, it means that the pump operation starts at a low temperature. Make sure you set
the pump according to the indications and you install a return temperature protection system
as indicated.
