General
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 ap-
prox. 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 accumula-
tor 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.

Wood firing
General instructions
The wood is placed on the ceramic grate. Suitable wood
size is 0.3-0.4 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 sec-
ondary chamber. The ceramic inserts cause the tempera-
ture 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 determin-
ing 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 1000–1300 kWh/
m3. The heating value for hardwood is about 1100-1500
kWh/m3
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 tempera-
tures between 300–900°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 de-
sired, 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 tempera-
ture by about 7 °C.

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 ce-
ramics 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.

”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 ce-■
ramics).
Wood firing
Sweeping
The sweeping carried out by a chimney sweep includes
all flue gas routes from the hearth to the top of the chim-
ney. 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 sec-
ondary 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” .
Ash can still contain glowing embers after
a long time. Therefore, always use a non-
inflammable container when emptying ash
and soot.
Note!

For the Installer
General information for the installer
Boiler room
The boiler room must be built in accordance with applica-
ble building regulations.
Provision for good air supply. The boiler room’s air intake
must be as large as the smoke pipe duct.
Chimney
VEDEX 1000 has a vertical flue pipe connection with an
external diameter of 133 mm.
Different chimney heights are required depending on ver-
sion. 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 aforemen-
tioned 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.

For the Installer
General information for the installer
Remove the turbulators in number order until the flue gas
temperature in the chimney is correct.
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 unfavour-
able 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 15–25°C.

LEK
The flue gas temperature must not drop
below 65 °C 0.5 m below chimney opening.
Note!

11VEDEX 1000
For the Installer
Pipe installation
Connection
The pipe installation must be carried out in accordance
with applicable heating and hot water norms. Internal sup-
port 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.
Filling
Fill the boiler using a fixed filler line to one of the expan-
sion connections or a hose in the drain valve.
Draining
Drain by connecting a hose to the drain valve. The con-
nection 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 sup-
plied.
Cooling coil
VEDEX 1000 is equipped with a cooling coil (22) for con-
nection to a temperature limiting valve. Refer to the manu-
facturer’s instructions when installing.
Min 2,5 m
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.
WARNING!
!
The pipe work must be flushed before the
boiler is connected, so that any contami-
nants do not damage the component parts.

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.

When the boiler’s temperature exceeds the set charge
temperature on the control unit (at, for example, 65 °C)
the charge pump starts, which then transfers heat from
the boiler to the accumulator. The electronic charge con-
trol ensures that the water temperature to the bottom of
the boiler does not drop too much that there is a risk of
condensation.
Charger pack 2 is recommended for this connection.
