Therefore, we ask you to CAREFULLY READ THESE INSTRUCTIONS, which will help you to achieve the best possible results already during the initial use.
These SENKO cookers are intended for cooking, baking, space heating and central heating! The cooker is packaged in a EURO pallet. During transport, the cooker must be properly fastened in order to prevent tumbling or damages. The standard delivered cooker set consists from: cooker, instruction manual, chimney terminal extension (23), firing regime adjustment – grate lifting spanner (24), cooker cleaning tool (25), CF agent for removal of soot and grease from glass surfaces (26).
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 1.2. wood briquettes: energy content at approx.
1.3. CHIMNEY The cooker is connected to the chimney via 150 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 150 mm diameter smoke venting pipe.

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).

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 (water, thermal protection, chimney, air inlet), inspection hatches must be installed for system maintenance and servicing purposes. 4.1.
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 7b). Flue draught must be within parameters: for C-20 2P 12 ± 2 Pa, for C-30 2P 15 ± 2 Pa. The chimney must be at least 0,5 meters above the roof ridge.
PROPER IMPROPER figure 7 Differences between the proper and improper connection of the cooker to the chimney SENKO cookers 2P extra rustik and glass – Instruction manual 15
Connect the cooker to the chimney using a sliding rosette, 150 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 keep the cooker removed from the chimney opening, use the standard smoke outlet pipe, 150 mm in diameter. 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 fresh air vent must be situated near the room floor and allow the inflow of fresh air into the room. The minimum dimension of the vent must be 6 cm per kW of nominal power (e.g. for 30 kW 180 cm 2 2 10 x 18 cm vent). A pipe can also be installed on the existing opening 150 x 80 mm (30) on the rear side of the cooker for the purpose of entering fresh outside air. 4.5. OVEN THERMOMETER Thermometer (32) indicates the oven temperature; this value is informative.
Prior to connecting the boiler to the heating installation, the pipelines are to be thoroughly cleansed from potential filth sediments. This prevents boiler overheating, system noise, pump malfunctions and mixing valve malfunctions. The connection to the heating system is executed via union flat joint, with or without the mixing valve onto an open or closed system.
Installation of an approved safety valve with opening overpressure set to 2,5 bar is mandatory in closed systems. Safety and expansion conduits must not have any kind of block elements. It is necessary to install the deaerating valve. When filling the boiler and the radiator system it is necessary to open the mixing valve, if one had been installed; adequately deaerate the boiler and the heating system.

4.6.2. INSTALLATION TESTING Prior to initial firing it is necessary to check if the boiler and the entire heating system are filled with water and well deaerated. Also check if the smoke uptake pipe is properly fastened. After initiation make sure: there is no leakage of any kind, that the entire installation is deaerated, that the water temperature in the boiler is increasing, that boiler operations do not result in condensation (“sweating”) in the chimney.
5. HANDLING THE PRODUCT holding the cooker frame is not allowed while handling the appliance ! 5.1. DIRECTING THE FLUE GAS Flue gas deflector (17) accelerates the expulsion of flue gas from the cooker when this is necessary. It is primarily used during initial stages of extra rustik cooker firing or when larger quantities of fuel are added into the firebox.
5.2. AIR ADJUSTMENT AND REGULATION CHIMNEY If the chimney is equipped with a vent damper, it must be adjusted to keep the chimney flue draught within the limitations: for C-20 2P 12 ± 2 Pa, for C-30 2P 15 ± 2 Pa. PRIMARY AIR Primary air is the air that flows directly through the firebox grate. There is an automatic max primary air regulator (12) between the fuel box (15) and ash box (14).
There is a rectangular connection point for the intake of external primary air on the cooker rear side, onto which a rectangular pipe (30), dimensions 150 x 80 mm, can be connected. If necessary, the rectangular cross-section may be reduced and turned into a round opening (minimum diameter 100 mm). The connecting pipe or the reduction must be made out of non-flammable material (in accordance with DIN 4102-B1).
5.3. FIREBOX GRATE Cooker firing regimes differ during summer and winter (winter and summer regime) – figure 5. The regimes are determined by the position of the lower firebox grate. In C-30 2P cooker : summer regime – the grate is used in the upper firebox position, winter regime – the grate is manually placed into the lower firebox position.
5.4. FIRING 5.4.1.
Adding fuel in regular intervals, in quantities of 2 to 4 kg, is recommended. When using the oven for baking, it is recommended (to maintain constant temperature in the oven) to add 0,5 kg of fuel in regular intervals. It is also recommended to rotate the tray from 180 halfway through the baking process to ensure uniform baking ! Cooker optimum values may be achieved only if the cooker nominal power was chosen in accordance with the rules of profession and object energetic efficiency. 5.4.3.
WARNING! New fuel quantities should be added only on top of embers, i.e., not on the flames, but only on top of embers (approx. 1 cm thick). Primary air automatic regulator (12) must be completely closed at least ten seconds before opening the firebox door (8) to prevent the breach of flue gases into the residential area. The door must be opened slowly. After adding the fuel, close the door slowly. Open the primary air automatic regulator (12) to decrease the time of fuel combustion.
5.5. OVEN DOOR Oven door are removed as shown in the following figure : figure 19 open the oven door all the way move the safety all the way back on the left and right oven hinges close the door halfway ensuring that the safeties lean against the door slits lift the ajar door upwards for approx.
6. CLEANING The cooker and the chimney must be regularly cleaned (at least once a month). The ash box (14) and the box area must be cleaned on daily basis. Ash disposal is to be executed in environmentally acceptable manner and in accordance with safety procedures. The glass (28) on the upper firebox door (8) should be cleaned as necessary using the soot and grease cleaning agent (26). The agent is delivered with the cooker ! The oven (9) should be cleaned after every instance of use. 6.1.
7. MAINTENANCE Following years of use, the chamotte insulation (consumable material) suffers damage that must be repaired with chamotte putty or refractory concrete. After several first hours of feeding, smear the fireproof paint on the upper plate with a cloth imbued with edible oil. Stainless material on the cookers is susceptible to slight colour change due to high temperatures.
straighten the capillary that contains the probe and pull the capillary downwards through the opening above the automatic regulator on the inside of the cooker.
7.2. FIRING REGIME SWITCH MECHANISM Mechanism may become jammed during use due to solid ash debris, metal parts (i.e. nails), feeding with inappropriate fuels, exceeding the cooker nominal power. It is necessary to remove and clean the mechanism in those instances. It is first necessary to check if only the grate is jammed. Remove the grate from the boiler and test the mechanism. If the mechanism cannot figure 22 be launched at that point, it is necessary to remove and clean it.
