CARE AND BOILER CLEANING
In order for your system to operate efficiently, regular maintenance is required by expert teams,
according to the manufacturer's instructions.
Regular checks:
The water level should always be checked. The hydrometer (water level indicator) should be
marked after the first filling of the system. If the water level has fallen below the static pressure or
system setting, water must be added to the system (when the boiler is cold). To protect the
system and the boiler against corrosion, the water to be fed to the system must be softened
according to the local settings.
It should be checked whether the front covers are closed properly and if necessary, the cover
wicks should be changed.
Check whether there is gas leakage from the flue connection. If there is a leak, it must be
repaired.
Boiler heating surfaces should be checked. Soot formation varies according to the type of fuel
used and the amount of combustion air. If it is understood that the leaving water temperature
does not rise to the values that it is usually in the usual conditions, the boiler surfaces are
processed, the heat transfer surfaces of the boiler should be cleaned.
The fan should be checked for proper operation. The fan that is not working properly and
balanced, makes periodic noises. If there are fuel dust or ash collected between the blades of the
fan, it is necessary to clean it by blowing or holding a dryer without disturbing the blades of the
fan.
Cleaning the boiler:
It should be done when the boiler is cold. Before cleaning the boiler, the pump and electrical devices
connected to the system must be turned off.
To clean the boiler:
Between the water jackets should be cleaned one by one. This cleaning should be done frequently
since the ashes and institutions remaining on the water jackets will prevent heat transmission.
Pitching that occurs on the walls of the boiler creates a layer, which will prevent the energy
released in the boiler from passing into the water, thus causing low efficiency. In order to prevent
this situation, all heating surfaces of the boiler should be cleaned at regular intervals or as
required.
The ashes that can remain on the water grill are pushed down and the ashes accumulated inside
the cleaning door at the front of the burner should be cleaned periodically or as required.
By opening the cleaning cover of the burner, the ashes accumulated in it can be cleaned in certain
periods.
The control panel should be protected from dust, moisture and water. The terminals behind the
panel must remain dust-free.
Boiler outer fairing sheets can be cleaned as required.
Maintenance:
Contracted service of the system before each working season; we strongly recommend you to call
our authorized service to check the boiler, installation, electrical connections, chimney. Never carry
out maintenance work without the help of an expert.
