31 CLEANING OF THE BOILER
The boiler should be cleaned at least once a year to remove carbon deposits from the heat transfer
surfaces
Open the door, open the cleaning door and take the turbolators out (you need to disassemble the upper part
of the real panel).
Clean the smoke pipes using a steel brush and remove the soot from and the rear cleaning door.
32 CHECKS AFTER THE BOILER CLEANING
After performing the maintenance and cleaning operations, repeat the preliminary operations prior
to switching on for the first time (see page 22),
check the burner setting and perform combustion analysis.
Check the fuel supply system seal: this check is particularly important when
using gaseous fuels.
Check that the combustion circuit is perfectly sealed and replace any worn gaskets.
Check the system hydraulic seal to avoid unnecessary exchange of water and topping up which will increase
the risk of scaling.
Should the boiler water ways be scaled, a chemical washing is needed to remove scale.
This operation must be performed by qualified companies.
The specifications of the plant water should be examined and, if needed, a treatment system should be
installed.
Never leave highly inflammable substance containers in the premises where the boiler has been installed.
