Product description VEDEX 1000 is an induced-draught boiler with efficient smoulder combustion. Max. wood length is 0.4 m. The boiler is designed to be connected to accumulator tanks with integrated water heater for heating domestic hot water. When lighting, the boiler water is partially heated by the fire and partly by the flue gas ducts. Max. output during wood burning operation is approx. 25 kw. Average output during wood burning operation is approx. 18 kw. Area of use VEDEX 1000 is intended for heating houses and other smaller buildings. Heating Hot water is taken from the top of the boiler and routed to the accumulator tanks. Return water from the accumulator tanks is lead via a charger pack to the bottom of the boiler. The hot water is led from the accumulator tanks to the radiator circuit via a shunt valve(sv1), where the desired temperature to the radiators is maintained by mixing the hot boiler water with the cold water that returns from the radiator circuit.

It shows the temperature of the boiler water level with the flow line connection. Boiler pressure gauge (42) The boiler s pressure is displayed here. The gauge is graded 0 4 bar with a red mark at 1.5 bar. Max. permitted pressure is 1.5 bar at 100 C. For a closed system, the operating pressure varies during operation depending on the installation s varying temperature. Direct damper (5) Controlling smoulder combustion. Pressed in position causes over combustion (start position). Pulled out position causes smoulder combustion (normal operating position). 4 VEDEX 1000

7 For Home Owners Wood firing Wood firing General instructions The wood is placed on the ceramic grate. Suitable wood size is m. To facilitate starting the boiler open the direct damper (5) (pressed in position), this gives a shorter smoke by-pass. The combustion process works by reverse combustion. The air in the boiler enters through the damper (61) and is pushed down to the lower part of the fire where combustion is concentrated. The combustion gases are drawn through the ceramic grate down into the secondary chamber. The ceramic inserts cause the temperature to increase to almost 900 C. More oxygen is supplied through the secondary damper and is mixed well, thanks to the turbulent flow, with the hot gases in the secondary combustion chamber where full combustion is achieved. Then these pass into the generously sized heat retaining surfaces. The convection part is equipped with removable turbulators. Type of wood, quality and moisture content are determining factors regarding lighting and fuel consumption. Dry wood can have a moisture content of 15 25%. If the moisture content increases to 30%, wood consumption becomes 10% greater. The heating value for softwood is about kwh/ m 3. The heating value for hardwood is about kwh/m 3 Extremely dry wood usually produces a large fire where unusually large amounts of gases are created, resulting in uneven combustion. To prevent this type of problem, it is recommended to use hard wood or a mixture of woods with a moisture content of about 18 20%. Carpentry off cuts should not be used. When the wood starts to burn it breaks up, whereupon combustible gases are created. These burn at temperatures between C. The gases make up 3/4 of the wood s energy content, the rest is in the created charcoal, which also eventually burns. Adjusting the draught regulator Remove the front panel between the doors by pulling it straight out. The regulator is installed so that the lever presses the damper. The door should be closed at the desired boiler temperature. If, for example, 85 C is desired, the boiler is fired to that temperature, whereupon the lever is adjusted so that the damper is closed when the knob is set to position 4. If a lower or greater temperature is required, turn the knob to the relevant setting. Moving between each marking on the knob changes the temperature by about 7 C. LEK LEK It is important that sufficient secondary air is supplied so that the gases burn off completely. Lighting for the first time It is important that lighting is carried out carefully in a new boiler so that any remaining crystallisation water in the ceramics is condensed slowly to prevent cracking. Before inserting wood Check that the boiler and other heating systems are filled with water. Flue gas thermometer (accessory) should be installed in the flue pipe. The turbulators should not be installed during the first few lightings. This is to increase the flue gas temperature and produce a better chimney draught until the boiler is lit and going. VEDEX

8 For Home Owners Wood firing Charge and circulation pump If a charge or circulation pump is not in operation for an extended period of time, it should be started anyway so that it does not jam. Commissioning Open the direct damper (5), pressed in position. Open the combustion chamber door (68) fully. Open the filler door (65). When starting with a cold smoke duct, first light a few pieces of screwed up newspaper to increase the chimney draught. Insert the screwed up newspaper and then finely chopped kindling wood. Light and close the filler door (65). Allow the fire to catch for about 5 minutes and then check that the flue gas temperature rises to a max. of 350 C. Starting smoulder combustion Open the damper door (61). Close the combustion chamber door (68). Add wood and pull out the direct damper (5) fully to the smoulder combustion position. Adjust the draught regulator (85). (see Adjusting the draught regulator) Note! To achieve a good start with a good bed of embers, the boiler temperature should increase approximately 20 C from the start temperature VEDEX 1000

9 For Home Owners Wood firing Rules of thumb when lighting wood The draught in the chimney is of extreme importance. It must be controlled to a minimum of 20 Pa, hot chimney. Light using hard or mixed wood (stored indoors). See lighting wood General instructions. The size of the logs must correspond to the size of the fireplace. Stack the wood as well as possible. There must be a sufficient supply of air. Secondary air must be supplied in sufficient amounts. Corresponding to the amount of fuel. Ensure that the fire temperature increases quickly. Ensure that the grate is not blocked. Poke and stir the fire before adding more wood. Open the direct damper before opening the filler door. Open the direct door in stages. Do not throw the wood in (this can damage the ceramics). Sweeping The sweeping carried out by a chimney sweep includes all flue gas routes from the hearth to the top of the chimney. You can check the boiler s fire-affected surfaces and flue gas ducts yourself to determine how often the boiler should be swept. Gas, which contains tar substances, builds up in the wood magazine. These substances condense on the walls of the wood magazine and are later burned off. This means that the walls of the wood magazine do not usually have to be cleaned. The convection part is cleaned by removing the top soot door (66), pulling up the turbulator and brushing clean. This should be done a few times between chimney sweep visits. For optimum combustion and efficiency the boiler s secondary combustion chamber should be cleaned after about 15 additions of wood. The compartment is cleaned from the front via the lower door by pulling out the flame trough and brushing. Take care to remove any burnt on ash remains in the trough. Also see For the chimney sweep, under Sweeping. Note! Ash can still contain glowing embers after a long time. Therefore, always use a noninflammable container when emptying ash and soot. VEDEX

10 For Home Owners Causes and corrective action in the event of malfunctions Causes and corrective actions Low room temperature Incorrectly set shunt valve (during manual shunting). Air in boiler or radiator system. Closed valve in the radiator circuit. Switched off or jammed external circulation pump, see section Helping the circulation pump to start". High room temperature Incorrectly set shunt valve (during manual shunting). Helping the circulation pump to start Switching off the circulation pump. Remove the protective hood and slacken off the venting screw. Hold a cloth around the screwdriver blade as a certain amount of water may run out. Insert a screwdriver and turn the pump rotor. Screw in the venting screw. Start the circulation pump and check its function. Secure the protective hood in place. It is usually easier to aid the circulation pump to start if it is off. If helping the circulation pump to start when off, be prepared for the screwdriver to jerk when the pump starts. Low hot water capacity Too small external water heater. Abnormally large hot water outlet in relation to the external water heater s volume. Mixer valve set too low (if applicable). Closed or throttled shut-off valves for the water heater. Protective Skyddshuv hood Venting Luftningsskruv screw LEK 16 If the cause of the operating disturbance cannot be localised and remedied by means of the above, an installation engineer should be called. 8 VEDEX 1000

11 For the Installer General information for the installer General information for the installer Boiler room The boiler room must be built in accordance with applicable building regulations. Provision for good air supply. The boiler room s air intake must be as large as the smoke pipe duct. Note! Ensure that sweeping can be carried out in accordance with the applicable regulations. If in doubt, contact a chimney sweep. Chimney VEDEX 1000 has a vertical flue pipe connection with an external diameter of 133 mm. Different chimney heights are required depending on version. In addition, a number of other factors, for example, wind and terrain conditions, nearby buildings etc, can affect the draught conditions of the chimney. Minimum chimney draught for satisfactory wood lighting is 20 Pa. If the draught is less than 15 Pa a flue gas fan should be installed. The following table showing several different versions of chimney is a recommendation, however, the aforementioned factors must also be taken into consideration. Draught regulator VEDEX 1000 is supplied with a draught regulator, which is installed to the left between the soot door and the filler door. Set according to the instructions. (see Adjusting the draught regulator). The regulator does not usually have to be inspected thereafter. The sensor is easy to replace without having to remove the draught regulator from the boiler.

12 For the Installer General information for the installer Assembly VEDEX 1000 has inlets for primary and secondary air on the front of the boiler. Therefore, always leave a space of at least a metre from combustible material. In unfavourable cases puffs from combustion can discharge sparks. Turbulators Four turbulators supplied with boiler. These are located in the ducts in the boiler s convection part as illustrated. The turbulators effect the turbulence of the flue gases, which means that a greater amount of energy is transferred to the boiler water. The temperature in certain chimneys may become so low that there may be a risk of condensation build-up in the smoke duct. To increase the temperature in the chimney the turbulators can be removed, one at a time as illustrated. For each turbulator that is removed, the flue gas temperature rises from the boiler by C. Note! The flue gas temperature must not drop below 65 C 0.5 m below chimney opening. LEK Remove the turbulators in number order until the flue gas temperature in the chimney is correct. 10 VEDEX 1000

13 For the Installer Pipe installation Pipe installation Connection The pipe installation must be carried out in accordance with applicable heating and hot water norms. Internal support bushes should be fitted when a steel pipe or annealed copper pipe is used. The overflow pipe from any of the safety valves must be routed to a floor drain to prevent hot water splashes when checking the valves or when bleeding the boiler. The outlet of the overflow pipe should be visible. If the heating installation has an open expansion tank, the distance between the highest radiator and the expansion tank must not be less than 2.5 m.! WARNING! If filling via the radiator circuit, the shunt valve must be in a central position. Otherwise there is a risk of cracking one of the radiators. Filling Fill the boiler using a fixed filler line to one of the expansion connections or a hose in the drain valve. Draining Drain by connecting a hose to the drain valve. The connection dimension of the valve is R 15 (1/2 ) ext. and is recommended to be installed on an accumulator tank or a T-pipe on the return to the boiler. The drain valve is supplied. Min 2,5 m Cooling coil VEDEX 1000 is equipped with a cooling coil (22) for connection to a temperature limiting valve. Refer to the manufacturer s instructions when installing. Note! The pipe work must be flushed before the boiler is connected, so that any contaminants do not damage the component parts. VEDEX

14 For the Installer Docking Docking General When docking the accumulator tank to VEDEX 1000 it can be useful to use one of the material kits available on the market for accumulator docking. For optimum function, the accumulator s charger pack must produce 65 C in return temperature to the bottom of the boiler. The following section describes the principle of such a connection.
