SENKO cookers SG – Instruction manual 6
1.1. FUEL
The use of moist and low-calorie wood is not recommended. The wood
moisture must be lesser than 17%. The energy content of moist wood is
low, at approx. 2,3 kWh/kg and it greatly pollutes the door glass, as well as
the chimney and the cooker.
Use only recommended
fuel:
wood: common beech,
common hornbeam, oak,
black locust
air dried for a minimum
of 2 years
relative humidity 15-17%,
energy content at approx.
4,2 kWh/kg
wood briquettes: energy
content at approx. 4,4
kWh/kg
1.2. FEEDING
manually when necessary
we recommend the logs to be of 50 x 50 mm vertical cut, up to 2/3 of
the firebox length
use smaller logs for a more intensive fire, and more massive logs to
maintain fire
the minimum distance between the logs must be 1 cm, the same
distance of 1 cm applies for the briquettes
to maintain constant oven temperature, add smaller quantities of fuel
occasionally approx. 0,5 kg
it is necessary to use protective heat insulated gloves when adding
fuel to the firebox
protective heat insulated gloves must also be used when opening and
closing the oven and firebox door and removing the tray from the oven
and ash box.

SENKO cookers SG – Instruction manual 7
1.3. CHIMNEY
The cooker is connected to the chimney via 120 mm diameter sliding
rosette. It is necessary to execute the connection of the rosette and the
chimney tightly and impermeably. If the cooker is separated from the
chimney opening (not recommended) the connection is made via standard
120 mm diameter smoke venting pipe –see chapter 4.3 .
We also advise to equip the chimney with solid material and possible
condensation products collection chamber and to install the chamber in
question beneath the smoke channel inlet, in a manner which allows easy
access and inspection via impermeable door.
IMPORTANT
BEFORE connecting to the chimney it is necessary always to make a
calculation (according to EN 13384 and all other standards for the
chimney dimensioning)!
The chimney has a very important function of the smoke exhaust at
solid fuel heating devices and therefore MUST BE well and properly
dimensioned!
1.3.1. CHIMNEY CAP
Chimney cap must fulfill the following prerequisites:
identical internal diameter to that of the
chimney,
operational exit cross-section no less than the
double inner diameter of the chimney –see B ≥
2×A in the Figure beside,
constructed to prevent rain, snow, leaves and
other foreign bodies from entering the
chimney,
constructed to enable expulsion of combustion products in case of
wind from any direction and incline,
installed to enable proper dispersion and dilution of combustion
products outside the reflux zone (backflow) because the counter
pressure occurs here. Therefore, it is necessary to adhere to limitations
listed in Figure 2 ,
mechanical appliances for flue gases suction are not allowed.

SENKO cookers SG – Instruction manual 8
1.3.2. CHIMNEY FUNCTION
Among all the meteorological and geographical factors that influence
the chimney function (rain, fog, snow, insolation period, etc.) the wind is
most certainly the crucial one. Apart from the pressure caused by the
temperature difference between the flue gases and the outer chimney air,
there is another type of pressure –wind dynamic pressure.

Ascending wind ALWAYS has the effect of increasing the pressure,
i.e., underpressure (flue draught), provided the chimney is properly
installed. Descending wind ALWAYS has the effect of decreasing the
draught overpressure occurs. Apart from wind direction and velocity,
chimney position in relation to the house roof and surrounding area is also
important ( Figure 3 ).
The wind also influences the chimney function indirectly by creating
areas of high (overpressure) and low (underpressure) pressure, both inside
and outside the residential area ( Figure 4 ).
Pressure that facilitates chimney function can occur in rooms directly
exposed to the wind (B), but it can also adversely affect the chimney
through external pressure if the chimney is situated on the side exposed to
wind (A). Contrary to that, underpressure can occur in lee rooms (C),
adversely affecting functions of the chimney situated on the opposite side
(D) from the wind direction.

1.4. INSULATION
Cooker is to the outer surfaces isolated with chamotte plates 20 mm
thick. The sides are chamber derived and cooled with the natural air
circulation. The depth of the chamber is 25 mm. Other parts of the cooker
interior are lined with chamotte brick, 40 mm thick.
2. WARNINGS AND SAFETY
When connecting the cooker to the chimney, adhere to national and
European norms and local regulations.
PROCEDURE IN CASE OF CHIMNEY FIRE
In case of chimney fire, close the openings for the air inlet and DON’T open
the firebox door. Extinguish the fire using appropriate fire extinguishers.
NEVER EXTINGUISH A FIRE WITH WATER! In case of fire also call the local
fire department. Comply with local regulations for fire protection!
Prior to use, verify with the local authorized chimney-sweeper whether
the cooker is properly connected to the chimney (the chimney-sweeper
must complete the installation report at the end of this Manual ).
Special attention must be paid that there is enough air for combustion
being supplied to the room cooker is installed in.

3. TECHNICAL FEATURES
SENKO cookers SG are intended for cooking, baking and household
heating. They are equipped with an oven just like the traditional kitchen
cooker. Cookers are suitable for installation between other kitchen
appliances (with ensuring minimum safety distances –see chapter 4.1. )
without heating risks.
They are made of stainless steel plates and castings of quality grey
casts. The cooking plate (1) is made of 8 mm thick steel plate. Cooker
interior is lined with chamotte.
The fuel box (12) is on the frontal side, at the bottom, just above the
manual primary air regulator (10) and the ash box (11). Above them is a
firebox (6) with a grate (16) and the oven (7) with door and thermometer
(18).
Also, the cooker is on the front equipped with two handles, one serves
as a flue gas deflector (14) and is located on the side where is the chimney
connection point, while the other (15) serves as a lever for moving the
firebox grate (16) – only at cookers SG-75 and SG-90 .

4. INSTALLATION
Once you have removed packaging from the cooker, it is necessary to
make a detailed inspection in order to determine any potential damages
that might have occurred during transport. Nay detected damages must
instantly be reported to the manufacturer.
In places of any connection points on the cooker (chimney, air inlet),
inspection hatches must be installed for system maintenance and
servicing purposes.
4.1. POSITIONING
A spirit level must be used to place the cooker in a horizontal
position with no incline. It is necessary to ensure the minimum distance of
the cooker from any flammable objects; such as wood, chipboard, cork
and similar. If the materials are easily combustible such as PVC,
polyurethane and similar, the necessary safety distances need to be
doubled.
The minimum distance from any flammable surfaces above is 1000 mm
and in front of the cooker is 800 mm, and 200 mm in all other directions.
When mounting the cooker on the floor made from easily combustible
material (wooden floors), the cooker must be mounted on an insulating
non-combustible surface.
A cooker should not be placed in rooms where there are gas stoves
or cookers, and in the bathroom, in buildings intended as laundries or

similar. The same applies for rooms or flats with air circulation or hot air
circulation with ventilation systems (air condition, extractor or kitchen
hoods), EXCEPT if such ventilation systems have safety mechanisms, which
sustain the air pressure above 4 Pa in a room, where the cooker is mounted
or in rooms which are in direct contact with exterior air.
It is recommended to place the cooker as close as possible to the
chimney hole, i.e. next to the chimney hole itself in order to avoid using
an additional smoke uptake pipe ( Figure 6a )!
If you want to set the cooker between the kitchen units, it is necessary
to ensure the minimum distances shown in the figure below.
The distance between the cooker and kitchen element is intended for
air circulation (cooling) –see the Figure above.
Here also you should take care on how to ensure access to a cooker for
maintenance and servicing.

SENKO cookers SG – Instruction manual 16
4.2. CHIMNEY PREPARATION AND CONTROL
Prior to cooker mounting, it is necessary to check the chimney –the
diameter, height, possible clogging or damages. The chimney must be
certified by an authorized local chimney-sweeper. The effective chimney
height must be at least 5 meters from the point of flue gases outlet
( Figure 6b ).
Flue draught must be within parameters 12 ± 2 Pa.
The chimney must be at least 0,5 meters above the roof ridge (see
Figure 2 ). The minimum distance between the two connections on the
same chimney must be 60 cm ( Figure 6d ).
Chimney diameter is chosen according to information provided by the
chimney manufacturer –e.g., for flue draught of 12 Pa, the diameter is
usually 130 mm.
The chimney must be smooth on the inside, well insulated and well
fastened. All cleaning hatches must be well fastened. All gaskets must be
regularly inspected and replaced when necessary.
4.3. CONNECTING TO CHIMNEY
When connecting the cooker to the chimney it is necessary to adhere to
local, national and European regulations (norms) –DIN 4705.
It is necessary to ensure that the connection between the cooker and
the chimney is executed tightly and impermeably. Smoke outlet pipe
must have a suitable incline (minimum 3°) in cases where the cooker is
removed from the chimney opening.
Smoke outlet pipe must not penetrate into the chimney clear
opening ( Figure 6c ).
Differences between the proper and improper connection of the cooker
to the chimney are displayed in the following figure.

by gently pressing remove the
following lid,
in place of the external lid attach the
sliding rosette with the same screws.
In doing so, you have remain the
external sheet metal of the rosette and
external lid (which are at the beginning
removed from the cooker), as excess.
Connect the cooker to the chimney using a sliding rosette, 120 mm in
diameter. Specially designed sliding rosette enables the adjustment of the
chimney opening in tolerance of 1,5 cm upwards, i.e. downwards.
In case it is necessary to connect the cooker to the chimney with
vertical uninsulated pipe, use the smoke outlet pipe, up to 125 cm
maximum length.
It is not allowed to reduce the prescribed pipe diameters!
If the cooker is further removed from the chimney opening, it is
connected via extension tube and an elbow. The extension smoke inlet
pipe must have an appropriate incline (see Figure 6 )and must not exceed
100 cm in length. The connection of the chimney and the smoke inlet pipe
must be completely fastened!
