SG SERIES - ENERGY CLASS A
4 / 5
Layers of soot (ash) in the chimney, which reduce its diameter.
Cracks in the walls of the chimney.
Loose pipes or pipes that have been placed too deep reduce beneficial section of the chimney.
Common chimney for many heaters.
In case of strong wind on the chimney which results to high pressure.
In case there are open windows on the last floor apartment or the chimney isn't air-locked the result is
reversed traction.
In case of rapid increase of temperature.
5. CLEANING AND MAINTENANCE
Regular cleaning allows the proper function and long life of the heater. The cleaning of the internal or external
surfaces must, always, be done when the heater is cold.
Cleaning of the external surfaces
should be done with a soft cloth which will not ruin the surfaces of the heater.
Chemical cleaning products can be used without ruining the heater. Do not clean the painted or enamel surfaces with
abrasive products.
Cleaning of the internal surfaces
should be done when the surfaces are cold and with the use of protective gloves.
Clean the interior walls of the combustion area from soot and remains of unburned substances, clean the ash
receptacle, as well as the remaining ash in the heater.
Cleaning of glass surfaces.
The glass door of the heater gets dirty during the function of the appliance because of
soot. For its cleaning use mild cleaning products. Do not use abrasive products which may ruin the glass surface.
Clean the glass surface when it is cold.
Cleaning and maintenance of the chimney
must be done at least once every year, as well as after a long period of
non-use. Regular maintenance and check of the chimney prevent the possibility of fire and weak function of the
appliance.
6. COMBUSTIBLE MATERIALS ALLOWED
As mentioned above, the use of solid fuels, only, is required for the combustion, such as briquette and wood. The
important factors that affect the thermal efficiency of wood are humidity, storage manner and type of wood.
The wood needs to have dried out within a period of, at least, two years before the burning. The ideal moisture content
in wood ranges between 12%-15% and not higher.
The wood storage should be achieved in the following way:
The storage should be achieved in such way, that it allows air circulation among the woods, for understandable
reasons. Protection from rain and snow should be insured. The lower layer of the woods shouldn’t be in direct contact
with the ground. If the woods are storaged in a closed room, make sure that there is no humidity in the room and
refresh the air in the room regularly.
