Heating
Hot water is taken from the top of the boiler and routed
to the accumulators. 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 accumulators to the
radiator circuit via a shunt valve (SV1), where the desired
temperature to the radiators is maintained by mixing the
hot accumulator water with the cooled return water from
the radiator circuit.

When the green light comes on, the flue gas thermostat’s
set temperature has been reached.
Flue gas thermostat
This thermostat starts and stops fans and any charge
pumps during lighting and extinguishing phases. The
thermostat is delivered connected for charge control by
thermal valve. i.e. the flue gas thermostat only starts and
stops the flue gas fan. To prevent stationary losses via
VEDEX 3300, reconnection to charge control without
thermal valve is recommended. The flue gas thermostat,
together with the boiler thermostat, then starts and stops
the charge pump.

Settings, instructions and maintenance
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” .
Charge and circulation pump
If a charge or circulation pump is not in operation for en
extended period of time, it should be started from time to
time so that it does not jam.
Ash can still contain glowing embers after
a long time. Therefore, always use a non-
inflammable container when emptying ash
and soot.

Settings, instructions and maintenance
General instructions
The way the wood is chopped, its type and moisture con-
tent are all determining factors that affect the function
and efficiency of the boiler.
Adjust the size of the wood to fit the hearth. Suitable
length of chopped wood for VEDEX 3300 is 0.5m.
The wood is placed on the ceramic grate.
The combustion process works by reverse combustion
where the combustion gases are forced down through the
grate by an induction fan. The fan is controlled by the flue
gas temperature. A damper ensures that a self induced
draught does not occur when the fan is off.
The fan works at two speeds which means that the high-
est speed occurs when adding wood and normal speed
during operation.
A tilting smoke stop prevents blow back.
Always use dry wood. Wood with a high moisture content
reduces the combustion temperature and causes increased
amounts of environmentally harmful emissions as well as
reducing efficiency.
Extremely dry wood can cause a large fire which can
create large amounts of gas. In addition, there is a risk
of flashover, which in turn causes irregular combustion.
Carpentry off cuts can be used but should be mixed with
other wood. All wood over 10 cm must be chopped. Only
use untreated and clean wood.
Combustible gases are created as the wood heats up.
These burn at temperatures between 300 - 900°C. The
gases make up 75% of the wood’s energy content, the
rest is in the created charcoal, which also eventually burns.
Final combustion occurs in the compartment under the
grate after the supply of secondary air.
Primary air control
The control damper on the front of the boiler is used to
distribute the air supply to the hearth.
In the left position the air supply is from the top of the
■
combustion chamber.
In the right-hand position, the air supply is from the
■
lower part just above the ceramic grate in the hearth.
In the central position the air is distributed equally from
■
both inlets.
Fluegas thermostat
This thermostat senses the flue gas tempera-
ture. When the temperature has been reached
and the filler door closed, the fan resumes
normal speed. When firing is ended and the
flue gas temperature has dropped, the fan is
stopped by the thermostat.
Max.thermostat
This thermostat stops the fan when the boiler
water temperature is too high.
Charge thermostat
This thermostat starts the charge pump at the
set boiler water temperature.
Before adding the first pieces of wood, check
that the boiler and the heating system are filled with wa-
ter, and that the flue gas thermometer is installed in the
flue pipe. Then make settings as follows.
Set the flue gas thermostat to position:
■
Set the max. thermostat to 90 °C.■
Set the charge thermostat to 70 °C.■
Adjust the primary air damper as follows.■
1 Hard and mixed wood
Adjust the damper to the right.
2 Softwood
Adjust the damper to the left.
For a newly installed boiler, new adjustments should be
made if combustion is not efficient and poor or if another
type of wood is used. Also see section “Wood firing”.

Wood firing
Lighting instructions
It is important that initial firing is carried out carefully in a
new boiler so that any remaining crystallisation water in
the ceramics is condensed slowly to prevent cracking.
Add approximately 4 kg of finely chopped kindling
■
wood and then tightly screwed up newspapers on top.
Light the newspaper and leave the filler door ajar.
Wait until the wood has caught fire properly (flue gas
■
temperature approximately 130 – 150°C) and the
green light comes on.
Close the door and let the fire burn to a bed of em-
■
bers, approximately 30 – 45 minutes depending on the
amount of wood.
Once a bed of embers has been created, more wood
■
can be added.
Check that the flue gas temperature rises, this is a sign
■
that combustion has started.
The boiler is now in normal operating mode.
Add more wood when a bed of embers remains at the
■
bottom of the hearth.
Adding wood
Add wood via the filler door. When this door is opened, a
microswitch is affected, which, in, turn increases the speed
of the fan.
It is important that the amount of fuel is adjusted accord-
ing to the temperature levels in the accumulator system so
that it does not become overcharged.
Even out the embers before adding more wood. Then
close the filler door. The speed of the fan is now slowed
and normal operation resumed.
VEDEX 3300 is designed for 0.5
m long pieces of wood. Stack
the wood well when adding.
Start by laying three logs as
marked in the image. Position
the logs so that they do not ob-
struct the grate hole. If shorter
pieces of wood are used, stack
these over the grate hole to-
wards the rear wall.
When the wood in the boiler has been burned and the
■
flue gas temperature drops to 80 – 85 °C, and a mini-
mal bed of embers remains, the green light should go
out, if not, readjust the flue gas thermo-
stat.
It is now set and should not need further
adjustment. At the next firing procedure,
the green light automatically comes on
when the flue gas temperature has reached approxi-
mately 80 – 85°C.
Readjustment
The flame can be checked through the sight glass af-
ter about 30 minutes operation. The colour of the flame
should then be yellow with a light blue tint.
The following points should be observed for VEDEX 3300
to perform optimally:
Follow the lighting procedure by checking the flue gas
■
temperature.
The fan should never stop during the firing cycle.
■
When the accumulator is fully charged, there should■
no longer be any wood in the wood magazine.
Never open the combustion chamber door during op-
■
eration.
The combustion of wood can vary depending on its
■
moisture content and type as well as on the position of
the primary air damper.
If the wood is not fed downwards and the flue gas
temperature is low, this may be due to an insufficient
amount of air being drawn in through the primary air
ducts. Adjust the damper to the left.
If the wood burns as in
case (A), the air supply is
too great from the top and
too low from the middle.
If the wood burns as in
case (A), the air supply is
too great from the middle
and too low from the top.
The correct air flow as per
case (C) gives the most ef-
ficient combustion.
It is not necessary to adjust the primary air damper if
any of cases fallen (A) and (B) occur on the odd occa-
sion.

For the Installer
Assembly
VEDEX 3300 has inlets for primary air at the front and
secondary air on the sides of the boiler. Therefore, always
leave a space of at least a metre from combustible mate-
rial. In unfavourable cases “puffs” from combustion can
discharge sparks.
Turbulators
Six turbulators are supplied with boiler. These are located
in the ducts in the boiler’s convection part as illustrated.
The turbulators affect the turbulence of the flue gases,
which means that a greater amount of energy is trans-
ferred 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.
Remove the turbulators in number order until the flue gas
temperature in the chimney is correct.

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 3300 has a vertical flue pipe connection with an
external diameter of 133 mm. Angled flue pipe supplied as
standard.
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 firing is 15 Pa.
The following table showing several different versions of
chimney is a recommendation, however, the aforemen-
tioned factors must also be taken into consideration.
Material Area Minimum

Steel pipe Ø 125 mm 5.0 m
Brick 140 x 140 mm 5.0 m
Many older boilers have the flue duct located down below
and will have been connected to the chimney near to the
floor. If the new boiler is to be connected higher up on the
chimney the lower non-active part of the chimney pipe
should be filled with sand or similar.

For the Installer
Pipe installation
Connection
The pipe installation must be carried out in accordance
with current norms. Internal support bushes should be fit-
ted 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.
Min 2,5 m
The pipe work must be flushed before the
boiler is connected, so that any contami-
nants do not damage the component parts.
Note!
Flue gas thermometer
VEDEX 3300 is supplied with an enclosed flue gas ther-
mometer which must be installed in the flue gas door
outlet.
Filling
Fill the boiler with water using a fixed filler line to one of
the expansion connections or a hose in the drain valve.
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!
!
Draining
The drain valve is installed next to connection (84). Drain
by connecting a hose to the drain valve.
Cooling coil
VEDEX 3300 is supplied with cooling coil (22) for connec-
tion to a temperature limiting valve. Refer to the manufac-
turer’s instructions when installing.
Environmentally friendly approved
To meet the environmentally approved requirements dur-
ing wood firing an accumulator tank of at least 1000 litres
must be installed with the boiler.

Docking to several tanks with thermal or electronic charge control and open expansion tank
When the boiler’s temperature exceeds the set charge
temperature (for example, 75°C) the charge pump starts,
which then transfers heat from the boiler to the accumula-
tor. The electronic charge control ensures that the water
temperature to the bottom of the boiler does not drop so
much that there is a risk of condensation.
Charger pack 2 is recommended for this connection.
Docking to thermal outlet with several tanks and open expansion tank
Note! Reconnection is required in the electrical panel for this type of docking. See ”Electrical installation” – ”Reconnection”.
When the boiler’s temperature and flue gas temperature
exceeds the set temperature on the relevant thermostat,
the charge pump starts, which then transfers heat from
the boiler to the accumulator tanks. Once all the wood
has been burned and the flue gas temperature drops, the
charge pump stops automatically.
The return line that is connected to the special thermal
outlet distributes the return temperature in the boiler in
such a way as to eliminate the risk of condensation.
Charger pack 1 is recommended for this connection.

Reconnection
The thermostat is delivered connected for charge control
by thermal valve. i.e. the flue gas thermostat only starts
and stops the flue gas fan.
To prevent stationary losses via VEDEX 3300, reconnection
to charge control without thermal valve is recommended.
The flue gas thermostat, together with the boiler thermo-
stat, then starts and stops the charge pump.
Reconnection must be carried out when docking to ther-
mal outlet. Carry out reconnection by moving cable 09
from terminal 12 to terminal 11 on terminal block -X9.
