3. INSTALLATION OF THE APPLIANCE
The installation, and counterpart connections, the activation and check of proper function must be followed
faithfully, according to the rules of your country and the given instructions.
The placement of the appliance near wood, freezers, plastic parts of furniture and other flammable materials is
FORBIDDEN, because of high temperatures development. The minimum distance between the heater and any other
object should be 50cm, and between the heater and flammable materials 80cm.
In case the surface, where the heater is placed, is flammable (wood, parquet etc.), the existence of a metal plaque in
between the heater and the floor is NECESSARΥ. The plaque should me extended by 10cm on each side of the
heater and 80cm on the front side.
Air-conditioning and ventilation appliances that function in the room, where the heater is placed, may cause troubling
with its function that should be arranged.
The diameter of the pipes must be equal to the diameter of the heater's exit. The heater must be connected to the
chimney with stove pipes. The pipe shouldn’t be placed too deep into The chimney, for prevention of the reduction of
the flue outlet diameter. The horizontal pipes should have a slight upward inclination and the vertical pipes should be
upright, although horizontal arrangement should be avoided for maximum efficiency of the appliance. The last pipe on
the inside of the room, where the heater is placed, should be warm enough, for prevention of liquefaction of waste gas
that may lead to fluid leakage in the house.
The external pipes and the chimney should be tightly fixed. The pipes should have a vertical finish and be higher than
any other obstacle around. The existence of a
Η-shaped pipe at the end is necessary. The part of the pipe, which is
on the outside of the house should be insulated for the maintenance of temperature and the prevention of liquefaction
of waste gas. The temperature of the waste gas is 240° C. The waste gases contain liquid elements with different
chemical composition and density, depending on the type of the fuel. These liquid elements cause liquefaction on the
inside of the chimney. In case of wood combustion, what is formed is creosote which is non-toxic, but there is the
danger of ignition.
4. FUNCTION OF THE APPLIANCE
The proven heat power was determined after research and development in the laboratories of
Gekas Metal.
It was
relied on mathematical models and confirmed by TTC ltd (European certificate center). To be achieved important
factors are, carefully selected fuels with the necessary efficiency and humidity, constant refilling, primary and
secondary air moderation, as well as traction.
The use of SG line heaters presupposes the existence of a chimney.
Start the lighting, by placing twigs (tinder) in the combustion chamber, starting a small fire for the prevention of thermal
shock. The primary and the secondary air moderators are open. To add more fuels in the heater make sure that the
previous amount of fuels has been burned. Close the two air moderators. In case of
SG1200
, after the closing of the
two air moderators (primary and secondary) open the afterburning moderator. Do not let the rack clog with remains
and unburned substances. Clean the rack regularly. Open the door slowly, carefully and not abruptly, allowing the
equalization of pressures in the combustion area and the room, otherwise fumes may leak out. The heater is designed
for functioning with the door of the combustion area constantly closed, unless when fuels are added. Do not open the
door unnecessarily. For maximum efficiency, the wood should have 20% maximum humidity, otherwise tar and fumes
are developed, which create creosote.
Also, it should be mentioned that the appearance of large or smaller cracks on the firebricks is absolutely normal,
even after the first use of the heater. This is caused by the phase difference of the materials' expansion (metal-
firebrick) and it doesn't affect the efficiency and function of the product. The firebricks endure up to seven (7), if they
remain in their place, despite the cracks they may develop.
Traction is the basic principle for proper function of the heater. It is achieved by the difference between atmospheric
pressure and pressure of the combustion point. The better the traction of the chimney is, the bigger the dimensions of
the door can be. In cases of lower traction, such as when we have more horizontal pipes than vertical, we are facing
the problem with the burning of twigs or paper, in order to achieve the heating of the chimney, i.e. gradual increase of
atmospheric pressure. The waste gas valve should remain open during the heating of the chimney, while you can
close it after that for cost-effectiveness.
