MAINTENANCE AND BOILER CLEANING
Regular maintenance is required by expert teams according to the manufacturer's instructions for
the efficient operation of your system.
Regular checks:
The water level should always be checked. Hydrometer (water level indicator) should be marked after
open filling system and pressure gauge shall be marked after the first filling of the system. The water
pressure level indicated when the water is cold in the manometer should be checked when the water
is cold, as the water pressure will increase as the water heats up. If the water level or pressure has
fallen below the static pressure or system setting, water should be added to the system (when the
boiler is cold). To protect the system and the boiler from corrosion, the water to be fed into the
system must be softened according to the local settings.
Check that the front doors are closed properly, if necessary, the door seals should be replaced.
Check for gas leaks from the flue connection. If there is a leak, it should be repaired.
The boiler heating surfaces must be checked. The establishment of the institution depends on 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 are generally in the usual conditions, the boiler surfaces are processed,
the heat transfer surfaces of the boiler should be cleaned.
Check that the fan is working properly. Unbalanced, balanced fan makes periodic noises. If there are
dust or ash collected between the fins of the fan, it is necessary to clean it by blowing it without
disturbing the blade structure or holding the dryer.
Cleaning the boiler:
The boiler should be done when it is cold. Before cleaning the boiler, the pump and electrical devices
connected to the system must be switched off.
To clean the boiler:
Smoke pipes of the boiler should be cleaned with cleaning brush supplied with the boiler. When the
brush is inserted into the pipes, it must be fully pushed and retracted. Otherwise, the wire brush's
wires will not return in the pipe and will not allow you to retract the brush.
The pitch of the boiler will form a layer and it will prevent the energy released in the boiler from
passing into the water and will cause a decrease in productivity. To prevent this situation, all heating
surfaces of the boiler should be cleaned at regular intervals or as required by the aid of squeegee.
The ashes accumulated in the smoke hood under the chimney and in the front of the furnace ash
cleaning door in the front of the casting hob should be cleaned periodically or as needed.
The control panel must be protected from dust and moisture. The terminals behind the panel must
remain dust-free.
The boiler can be cleaned as necessary.
Maintenance:
The contracted service of the system before each working season; boiler, installation, electrical connections,
chimneys, we strongly recommend that you call our authorized service. Do not do any maintenance work
without the help of an expert.
