Viking BIO is a forward burning pellet burner, for 8 mm
wooden pellets. A controlled mixture of fuel and air is brought
together in the burner's lined combustion pipes and this facili-
tates environmentally friendly combustion and a high level of
energy efficiency. The burner is intended for use with a con-
ventional oil or wood burning boiler.
The operation of the Viking BIO is very similar to that
of an oil burner – it is completely automatic and con-
trolled by the boiler thermostat. One feature is the
temperature sensor, which ensures that the burner
controls the boiler temperature. This function is par-
ticularly useful in boilers which generate hot water
via a heat exchanger.
In order to prevent operation
under the wrong circum-
stances such as the wrong
type of boiler, or poor
draught conditions, the burn-
er monitors back pressure con-
ditions in the boiler and closes down,
or will not start, where back pressure is
too great. The burner's safety system
also features a flame monitor and fan
control.
Different operational modes can be chosen: one step, modu-
lating, or boiler temperature control via the burner.
There is also a start delay feature, which extends
the unit's longevity and thereby raises efficiency
levels.
The cover on the burner has four indicators, which
(by flashing in different ways) provide information
regarding operational phases and alarms.
Automatic feeding of pellets to the burner is provided by
a screw feeder, which is controlled by the burner via the fuel
supply unit. Safety in this feed system is ensured by an over-
heating guard on the downpipe, a meltable pipe between the
screw feeder and burner and another safeguard which
prevents overload on the screw feeder motor.
In order to simplify installation and maintenance
procedures, the burner has quick release fas-
teners, which make assembly and dismantling
of the burner much simpler. All electrical con-
nections come with quick release devices.
The delivered unit includes a screw feeder, con-
nection cable, flue gas thermometer and an ash
rake, a temperature sensor and an expansion slot
are also provided as accessories.
The manufacturers retain the right to carry out
modifications without further notice.

General
Planning laws, or notifications, do not normally need to be
applied where the existing boiler can be heated using pellets.
Contact your local authority regarding any possible restrictions
on the use of solid fuel burning in built-up areas.
The flue
A flue, which has previously been used for oil burning, would
normally also be suitable for pellet burning; whilst a flue used
for wood burning may have too large diameter, requirements
are as follows:
Min: height 2 m, ∅100mm or equivalent.
Max: draught <20 Pa, corresponding to 8-9 m height.
The draught is measured whilst the the flue is warm and under
normal operation.
The boiler
The Viking Bio can be mounted on to most domestic boilers.
Pellet burning produces a certain amount of ash, which needs
to be accommodated. The removal of ash from the boiler
should also be relatively easy.
The boiler must be of the correct size in relation to burner out-
put, so that flue-gases are cooled to a suitable temperature.
The boiler smoke/gas ducts must not be so narrow so as to
prevent the free fall of ash residue.
If possible, the burner should be mounted onto the oil burner
hatch and preferably so that this can be opened without need-
ing to remove the burner; thus simplifying maintenance.
Wood burning boilers have larger spaces for ash and are usu-
ally easier to keep free of soot. An old wood burner is not usu-
ally a good choice as the heat absorbing surfaces are normally
too small to be able to cool down flue-gases sufficiently.
The boiler hatches and damper must be tightly sealed so that
air cannot penetrate the interior.
The flame must not be allowed to touch the walls of the boiler.
The boiler chamber's minimum measurements are 230 x 230 x
365 mm (h x b x d) see diagram below.
If the depth measurement of 150 mm cannot be obtained, it is
possible to build out the burner from the hatch; alternatively,
more packing can be used between the hatch and burner.
The distance to the bottom of the boiler should be deep
enough that there is enough space for a week's build up of ash
in winter conditions. The greatest amount of ash collects in the
deepest part of the boiler.
Assembling of burner
A. Loosen the three
screws which keep
the burner's cover
in position and re-
move it. Open the
quick release fas-
teners, release the
combustion pipe
with flanges from
the burner.
Mark out where the
burner is going to
sit and make a hole
according to the
adjoining diagram.
B. The burner flange and flange packing is mounted onto the
burner hatch and screwed
down with four times M6
screws. The burner must
be mounted horizontally, or
alternatively, sloping down
somewhat at the boiler.
C. Mount the burner on the
burner flange and close the
quick release fasteners.
Check that the burner tight-
ens against the sealant mate-
rial on the burner flange.
Assembling of downpipe
The downpipe must be screwed down onto the burner's frame.
The downpipe can be turned 22° in order to obtain a suitable
angle against the screw feeder.
1. Temperature delimiter with cable on downpipe.
2. The cable's connection tool is attached here.
3. The cable is attached using a tie band running along the burner as
shown in the picture.
Please ensure that the contact points are properly engaged.

The installation must be carried out according to current regu-
lations. It is the responsibility of the installer to be aware of
current standards.
A contraflow hatch must always be used. Where the flue
height is more than 5 m, a contraflow hatch must be used.
If necessary, a breaker (SW2/2) can be set at "high draught".
See "Contraflow hatch", page 10.
The burner hatch must be properly insulated.

Removable plates
Removable plates can be found on the sides of the burner's
cover. These are broken off when the burner is mounted on the
Värmebaronen boiler.
Assembling of screw feeder
The screw feeder's inlet should be at least 50 mm from the
bottom, but the important point is that this inlet is free from
obstruction. The distance from the opening to the nearest wall
should be at least 150 mm. Please check the position of the
screw before the supply unit fills with pellets.
H-measured at 40°:screw 1500 mm: 750 mm
screw 2500 mm: 1400 mm
The screw is connected via an attached pipe to the burner's
quick release catch on the downpipe. The pipe is secured at
both ends using pipe clips.
The screw feeder must be anchored securely as it will other-
wise work its way into the supply unit. Anchor the screw using
a chain suspended from the ceiling.
The screw feeder's electrical cable is attached to the electri-
cal terminal on the burner. Before the screw and burner are
started up, please refer to Screw Feeder on page 10.
A flexible screw feeder can be used with the burner, though an
intermediate supply unit must then also be used. Some of the
Viking Bios screws are then placed here in order to supply the
burner with fuel.
Installation
Pellet supply
The supply unit is designed so as to restrict the emergence of
too much dust and shavings in the burner room during filling.
It must be covered by a non inflammable material, perhaps
sheet metal or plasterboard.
It must be possible to remove the screw feeder without first
having to empty the supply unit.
The amount corresponding to a week's supply depends on
the heat requirements in the home. However, it is recommend-
ed that the supply unit can hold at least 300 litres.
Flue gas thermometer
The accompanying flue gas thermometer is mounted in a suit-
able position adjoining the smoke duct.
Supply air to burner room
A supply air valve must be fitted to the burner room, which
can give sufficient air to the burner. The valve's free surface
must correspond with the flue cross section area.
Safety
From a fire safety perspective, it is important that the the
burner room is clean and free of dust.
Flammable materials must not be kept in the burner room.
The burner room door must be kept shut.
Risk of snaring.
The feeder cable should be decoupled from the the burner
before any adjustments are made to the screw feeder.
In order that the correct dosage of pellets is provided, the
burner must be equipped with the appropriate screw feeder.
Setting adjustments must be carried out using the control unit
where the feed pipe is made of sheet metal or plastic.
The feed pipe slope from the horizontal plane must be 40°±5°.

The plug, 3, is pressed into the
socket part, 1, which sits on the
burner, until the catch on the push
button, 2, grips and locks the the
plug into position.
When decoupling, the current to
the burner must first be switched
off, after which the push button
is pushed in at the same time as
the plug is withdrawn from the
socket.
Safety switch
A safety switch should be mounted wherever the
boiler hatch can be opened without the need for
a special tool. Alternatively, safety regulations can be observed
by making the tube between the screw feeder and burner so
short that it has to be detached from the burner before the
hatch can be opened.
Boiler temperature control via burner
Where the burner is controlled by boiler temperature, a temper-
ature indicator must be included – accessory. The temperature
indicator is equipped with a contact which is connected to the
corresponding contact on the burner, see point 3 in the section
Connections/fittings on the burner.
Where the burner is not covered by a "normal" boiler thermo-
stat, the configuration can be set as per the diagram below.
An overheat device must always be included.
Allowing the burner to control boiler temperature is advanta-
geous when the burner is mounted on an boiler using a heat
exchanger for hot water services. The burner's temperature
regulation has a large differential, ±8°C, relative to set tem-
peratures, which reduces start and stop times and increases
operational life.
The temperature indicator for boiler temperatures should pref-
erably be placed in a pocket tube, or high up in the body of the
boiler under the isolator. In a boiler where hot water is provided
via a heat exchanger, the indicator should be placed in such
a way that it picks up the return flow, though not on the heat
exchanger's return pipe.
Where no pocket tube is available for the indicator, it can be
glued onto the body of the boiler using a double bond epoxy
resin. It is important that the indicator has good thermal con-
tact so that temperature regulation is both accurate and stable.
In the Värmebaronen Star heat exchanging boiler, the tempera-
ture indicator is placed in the pocket tube, which can be found
on the left hand side, behind the foldable automatics cabinet.
Electrical connections
This page shows how to install electrical connections for
Värmebaronen boiler.
The installation must be carried out according to current gen-
eral and local regulations, including those stipulations covering
any accessory equipment used in the electrical configuration.
The burner must be covered by a multi pole switch, 6A fuse.
The configuration chosen depends on the boiler upon which
the burner is mounted, and whether this boiler already has
electrical equipment in place. The configuration must, however,
follow the electrical diagram below.

• drier flue-gases, which reduces the risk of condensation.
The burner's haul factor is 0- 5 Pa, a higher draught gives igni-
tion problems, one or more of the following measures can be
taken:
• mount a contraflow hatch.
• set switch 2/2 in high draught position.
• mount a throttle plate at the top of the flue.
Agitators
Certain boiler types have, or can be equipped with, flue gas
agitators. Their job is to agitate the flue-gases so as to obtain
more heat and thereby raise efficiency levels. With low burner
output, flue gas temperature is low and there is a risk of con-
densation build up in the flue. Try to shorten the agitations
somewhat until a suitable flue gas temperature is obtained.
Smoke from the flue
The colour of the smoke reveals how well combustion is pro-
ceeding:
Grey brown: due to lack of air.
Invisible: heat shimmer, in temps. above freezing, or just below,
the smoke should be invisible.
White: with lower external temperatures, only a weak white
trail of steam should be seen.
Where the boiler has previously burned timber, the smoke can
be dark and have a strong smell because the tar in the boiler
and flue walls is being burned off. This can last for up to a
week.
Smoke emission
If the unit's hatches and damper are not sealed correctly,
there is a risk of smoke emission, particularly if overpressure
builds up in the boiler. If overpressure in the boiler is too great,
the burner will stop automatically. A smoke alarm can be a
great help in showing that flue-gases are leaking from the
burner room. Boiler hatches must be closed when the burner
is in operation.
The flame
The amount of air must be adjusted so that the flame is light
yellow. A few minutes after start-up, the flame should have a
yellow-white nuance. It is perfectly normal for the the colour to
vary between yellow and white.
The colour of the flame is an indicator of how well combustion
is proceeding:
Light yellow: good combustion, invisible smoke at normal tem-
perature.
Reddish: not enough air, or too much fuel, low efficiency level,
the boiler heat absorbing surfaces are blocked by
soot.
Important: short flame, due to surplus air, or lack of fuel, low ef-
ficiency level, high flue gas temperature.
Combustion values
The burner's delivery settings are not operational settings,
these must be adjusted in every single instance, using a flue
gas analysis instrument.
Correct adjustments are important so as to ensure fuel burn-
ing efficiency, a high level of energy efficiency, low discharge
of substances that may harm the environment, and also for
the longevity of those parts of the burner which come into
contact with flames. Optimum adjustments can only be
achieved using flue gas analysis instruments. The values state
how combustion should be proceeding. Please note, however,
that these values will vary somewhat in the ignition phase:
Flue gas temperature: 160°C1Efficiency level: >90 %
CO content: <300 ppm Boiler temperature: 75-80°C
CO2content, substance: 12,5 %2
1Dependent on type of flue2±2,5%
Check before first start-up
Before the burner is put into use, please check that:
• the installation has been carried out properly.
• the slope on the screw is 40°.
• all control units have been properly adjusted.
• the boiler is in proper functioning order.
• the burner is receiving sufficient air for combustion.
• pellets are being fed to the burner.
• the grate is in the proper position.
• the flue is fully intact and of the right dimensions.
Screw feeder
Before burning can commence, the screw feeder must be
filled with pellets.
1. Release the screw feeder's quick release device from the
burner. Place a collection receptacle under the tube.
2. Start the screw feeder by connecting it to an earthed wall
socket. Allow the screw to run until 25- 30 litres of pellets
have passed through the screw.
3. Remove the plug from the wall socket, reattach the quick
release device and the plug to the burner.
Flue gas temperature
Risk of injury.
Do not place your hands or objects inside the screw feeder.
The flue gas temperature after the boiler should be 160- 200
°C.
Higher temperatures may be due to soot blockage in the
boiler, or too much combustion air. High flue gas temperatures
cause poor efficiency levels and unnecessary pellet consump-
tion. An older boiler often has higher flue gas temperatures
than a modern type in similar conditions.
A low flue gas temperature may be due to poor combustion
because of a lack of air, or that the burner boiler is over dimen-
sioned, specially at low output settings on the burner. There is
then a risk of condensation in the flue with frost damage as a
result.
The flue
In order to avoid damage to the flue, flue gas temperatures
must be checked on every occasion.
During combustion, water builds up in the form of water drop-
lets, which follow the flue-gases out of the flue. Depending on
the drop in temperature, these droplets can condense to wa-
ter, which can then cause damage to the flue. Condensation
damage can be avoided if flue gas temperatures are no lower
than 70°C at one metre from the top of the flue. Low flue gas
temperatures give a higher efficiency level, which has to be
weighed against the risk of condensation. Measures to take
for raising flue gas temperatures:
• remove any agitators or baffle plates in the boiler.
• mount a contraflow hatch.
• isolate the flue in a cold environment.
• increase the burner's capacity
• mount an insert pipe.
Contraflow hatch
All pellet burning equipment should have a contraflow hatch.
For flues higher than 5 m, or with a high and/or variable
draught, this hatch is a statutory requirement.
Draught is affected by temperature, weather and wind. Given
that combustion results are affected by draught, stable
draught conditions are very much preferred. The simplest
way to stabilise conditions is to mount a contraflow hatch on
the waste gas flue. Air from the burner chamber slips into the
waste gas flue via the hatch, the advantages are:
• more stable draught and flue gas temperature.
• reduced losses when in idle mode.
• ventilation of the waste gas flue.

Operational mode – Modulating, double effect position
Modulating, automatic exchange between low and high out-
put.
Output low/high: 15/20 kW.
The burner switches to high output after being in low output
mode for 20 minutes.
Circuit breaker:
Temperature controlled
Boiler temperature regulation via the burner, with modulating
operation. The burner's temperature regulation controls the
boiler temperature with an engagement differential of ±8°C
relative to set temperature. The temperature setting is carried
out on the circuit board, point 21.
Boiler temperature indicator, accessory, must be connected to
the burner. Switches SW1/1 and SW1/2 are set to modulating
mode according to above diagram.
In idle mode, the burner detects the sudden drop in tempera-
ture, which can arise in a "heat exchange boiler" with hot
water provision. The burner then starts before the temperature
has dropped to its normal start value.
The burner switches automatically to high output mode if has
been in low output mode for 20 minutes.
Temperature control is also suitable when the burner is mount-
ed in a wood burning boiler with accumulator tanks.
The burner should be electrically engaged according to "Boiler tempera-
ture control via burner", see page 6.
Where the burner is governed by an boiler thermo-
stat, all its indicators will start to flash if it is
set at a lower temperature than the temperature
setting on the burner itself.
In the event that the boiler thermostat breaks
down whilst in operation, pellet feeding is ter-
minated, the burner switches to the cooling
phase and then closes down with all its indi-
cators flashing. Restart requires a reset
of the alarm – see Resetting the alarm
page 16. The boiler's thermostat must be
set at the highest value, the temperature
setting on the burner is set to at least 10-
15°C lower than this.
Start delay
With switch SW1/3 in the "ON" position, a start
delay of 0-135 minutes is obtained, as per
the setting at switch 25. Using this function
extends the burner's longevity, which raises
efficiency levels. This function can be used in
all operational modes, but is not suitable for
boilers where hot water is provided via a heat
exchanger.
Flue air flow
To ensure good operational economy, the flue air flow should
be <5 Pa, which is adjusted using the boilers flue gas damper.
In certain circumstances, the draught can be difficult to set
correctly. Flue air flow affects the time it takes for the burner to
ignite. The prevailing conditions are input with switch SW2/2,
see point 23 on page 9. Please see also the section – The flue
and the contraflow hatch on page 10.
Switch SW2/2: OFF: Normal position draught ±0 to -15 Pa.
ON: High draught: draught -15 to -20 Pa.
General
Because of the the screw's uneven feed ratio during the first day of use,
the adjustments should be checked after approx. a week's cycle.
Adjustments are always made in high output mode, delivery settings.
Adjustments must be carried out using a flue gas analysis instrument.
Authorised soot count on testing is 1- 3.
Adjustments
Please follow the points below in exact sequence when mak-
ing adjustments:
1. Checking settings.
Please check that the settings have the values shown in the
diagrams on page 9, points 22, 23, 24 and 26.
2. Adjustments – High output
A. Switches set according to dia-
gram:
B. Start the burner and allow it to
run for approx.
10 minutes.
Carry out a CO2measurement.
Adjust at "Fuel", nr 24. WhereCO2
value is:
Too low, increase "Fuel".
Too high, reduce "Fuel".
Due to variations, the test should be repeated several
times.
3. Adjustments Low output
A. With the burner running, the switches
are set according to diagram:
B. Allow the burner to burn for approx. 5
minutes, before carrying out a soot test.
Settings for fuel amounts
must not be changed.
Carry out a CO2measurement.
Adjust with "Air LOW Output",
nr 26.
WhereCO2value is:
Too low, reduce "Air LOW out-
put".

Operation – from start to stop
Operation – from start to stop
Viking Bio's operation procedure is very similar to an oil burn-
er. The big difference is that the start and stop phases take
much longer. Under normal conditions, it takes four to five
minutes before the flame is relit.
The burner's operational mode, from start to stop, is split into
four phases:
1. Start
2. Set flame
3. Operation
4. Cooling
Prerequisites for start:
•Overheating guard, thermostat and possibly closed safety
gates.
• Possible alarm reset.
• The burner receives pellets.
Start
•The thermostat demands heat.
If start delay has been chosen, the "RUNNING" indicator will
flash during the time that the set delay is active.
Where the burner controls the boiler thermostat, all its in-
dicators will start to flash if it is set at a lower temperature
than the temperature setting on the burner itself. The boiler's
thermostat must be set at the highest value, the temperature
setting on the burner must be set to at at least 10-15°C lower
than this.
•The fan starts and runs at top speed for twenty seconds in
order to ventilate the boiler and flue-gas channels. At the
same time, back pressure in the burner chamber is meas-
ured. If the result from five measurements shows too much
pressure, the burner stops and gives an "Overpressure –
burner chamber" alarm.
•The fan stops. A start dosage of pellets is given and the igni-
tion element begins to heat up. For a start dosage, the screw
runs about 3.5 revs.
•The fan intermittently goes into a flashing "LOW" indication.
When a flame is found, it switches to a fixed band of light.
The burner makes three attempts to start. The first try is de-
scribed above. Where a flame is not lit on the first attempt,
the fan will stop for a short time and then start again at a
low speed at the same time as the ignition element is re-
engaged. The third attempt is identical to the others.
If there is no flame after the third attempt to start, the fan
stops for a short period and then picks up speed in three
stages to a high speed.
The burner normally ignites at the first attempt and a flame
will be found after four to five minutes. Where the burner fails
to establish a flame, as described above, it will stop operat-
ing and a "Failed start" alarm will appear. The likeliest cause
for this is that the draught is too powerful, the grate is incor-
rectly placed, or the burner is not being fed with pellets.
Set flame
• Burner is running with flame.
•Fan sped increases in stages, so as to establish a stable bed
of embers on the grate.
•Pellets are fed in. The screw runs approx. a quarter turn for
each feed. Pause time depends on output setting.
If the flame disappears during this phase, the controls switch
to the start phase, but no pellets are fed in.
Operation
•Fan speed is determined by output setting. The "OUTPUT"
indicator gives a fixed or flashing light depending on the
operational mode. The "LOW" indicator lights up with a fixed
band.
•Pellets are fed in.
If the flame disappears during operation, a smaller amount
of pellets is issued and the ignition element attempts to cre-
ate a flame. "LOW" flashes and it switches to a fixed band of
light when a flame is found.
The burner then goes into "establish flame" mode in order
to gradually establish a stable bed of embers and then goes
into operational phase.
If the attempt to establish a flame fails, the burner will stop
and give a "Failed start" alarm.
The reason why a flame disappears is that the draught is too
powerful, the grate is incorrectly placed, or the burner is not
being fed with pellets properly.
Cooling
•Operational stop by thermostat.
If the burner controls the boiler temperature and is governed
by an boiler thermostat which breaks down whilst in opera-
tion, pellet feeding is terminated, the burner switches to the
cooling phase and then closes down with all its indicators
flashing. Restart requires a reset of the alarm – see Resetting
the alarm page 16. The boiler thermostat must be set at the
highest value, the temperature setting on the burner is set to
at least 10-15°C lower than this.
•Pellet feeding ceases.
•The "OUTPUT" indicator flashes – one long + two short.
•The fan runs at top speed and continues for 90 seconds af-
ter the the flame goes out. This is to ensure that all pellets on
the grate are burned. The "LOW" indicator goes out.
•If, for four cycles, the fan runs at top speed all pellets in the
grate will be burned up.
•The burner stops. Only the "RUNNING" indicator is lit.
Long running time
When heating requirements are substantial, or when burner
output is too small for the actual heating requirements, the
burner's running time is very long. In order to retain a good
combustion level and stable operation, the burner automati-
cally switches after approx. three hours in operation and goes
to its cooling/clean blowing phase, in order to blow clear any
ash residue which has built up in the grate. A reset to opera-
tional mode occurs automatically.

Lighting the pellets
Wooden pellets are an environmentally friendly fuel, which give
low discharge of materials that are harmful to the environment.
Due to the fact that each pellet is small in size, the flow of fuel
can be controlled to achieve the desired output setting. This
gives good combustion and high boiler efficiency levels.
Viking Bio is designed for an ∅8 mm wooden pellet. The ash
content for this wooden pellet is approx. 1 %. A bark pellet
gives more ash than a wooden pellet.
Combustion
The wooden pellet's energy content is approx. 4,7 kWh/kg.
Pellet burning produces a certain amount of ash, which needs
to be accommodated. The removal of ash from the boiler
should also be relatively easy. This means that it is important to
clean the boiler of soot on a regular basis, so that the cooling
of flue-gases is not adversely affected by the presence of ob-
structions on the heat absorbing surfaces.
If the combustion temperature is very high, ash particles will
fuse. If this happens, either the combustion temperature is too
high, or the pellets are of substandard quality with high ash
content. Please check the air settings. Please do not mix up
fused ash clumps with the easily removed ash cakes, which
may be present in the boiler.
Efficiency level
The aim is to achieve a high efficiency level, which means
extracting as much heat as possible from each pellet. In real-
ity, we are talking about reducing heat loss. Below we have a
description of the various loss factors which need to be mini-
mised:
Flue-gas losses: The heat contained in flue-gases which
escape via the the flue.
Losses when in When the burner is in idle mode,
idle mode.: the flue airflow sucks cold air through the
boiler so that it begins to cool.
Insulation losses: Heat loss via the boiler insulation. A small
part of this is retrieved by the fact that
combustion air is heated. Another part
may also be of overall benefit to the build-
ing.
With a lower output on the burner, flue-gases are cooled more
effectively, which gives a higher boiler efficiency level, longer
running time, and reduces losses in down time.
Hot water application in the summer-time
In the six coldest months of the year, approx 80% of annual
energy requirements are consumed. In this period, heating re-
quirements should be covered by pellet burning.
In that part of the year when heating requirements are low, and
mainly consist of hot water requirements, pellet burning is often
not advisable. In this period, the burner has short operational
periods, which leads to losses when in idle mode, efficiency
levels can be <30%.
The burner can be set for different outputs. A good rule of
thumb, is not to use the higher output option more than is nec-
essary for the prevailing heating requirements.
When heating requirements are low, it is advisable to use an
electrical element with the boiler, or alternatively, a separate
electrical hot water application. In the latter case, the boiler's
flue gas damper should be closed when burning with pellets is
not undertaken.
Be careful when closing your pellet unit as spring arrives and
do not start it up again until it is absolutely necessary.
Efficiency savings
Proper care of the unit, and regular adjustments, will ensure re-
duced fuel consumption for all those who make the effort.
Where the heating requirements on a cold winter's day go up to
145 kWh, 35 kg of pellets will be used with an boiler efficiency
level of 85- 90%. If the burner is not correctly set, this can go up
to 45 kg. This can make a difference of several tons per year.
Please check regularly that:
•the flame is light yellow.
•the smoke is invisible.
•the flue gas temperature has been adjusted.
•the boiler contains no ash or soot.
•the burner is running on the lowest output possible.
Pellet class
Some requirements regarding the pellets, as per SS 18 71 20
group 1:
Length: max 4 ggr ∅
(max 32 mm for ∅8 mm pellet)
Volume: ≥ 600 kg/m3
Fine parts < 3 mm: ≤ 0,8 weight %
Heat value: ≥ 4,7 kWh/kg
Ash content: ≤ 0,7%
Total moisture content: ≤ 10 weight %
Changing to a different pellet means that settings for the
burner must be rechecked and may also cause operational
problems.
Handling and storage of pellets
Pellet storage can be solved in different ways. The key point
is the storage area that is available and the work and cost in-
volved in setting this up.
The wooden pellet must be kept in covered storage but does
not require a heated environment, as long as the room is dry.
Installing a silo is one practical storage solution. There are
a range of options where silo design and placement is con-
cerned, or these can be bought "off the shelf".
Another alternative is to build a silo, bag silo, sheet metal silo,
plywood silo etc; a converted oil tank is also an option.
Pellets will run easily from a silo set at an angle of 40±5°.
However a problem can arise if the fuel contains a large
amount of fine particles, which can cause a damming problem
and promotes bridging at the bottom of the cone, thus pre-
venting free fuel flow.
Transportation of the pellet from the the supply unit to the
burner burner chamber is carried out using normal feeder
screws of various types, both fixed and flexible. The feeder
screw should not have too large a lift angle, nor be dimen-
sioned too narrowly.
Checking the screw feeder's capacity
1. Release the quick release device on the downpipe and
keep hold of the device, which is attached to tube.
2. Start the screw and let it run for 3. 5 – 4 revolutions.
3. The quick release device on the tube is filled with pellets.
If this does not happen, check the slope on the the screw
and the gap in the pellet supply unit.
Operation and Maintenance
Caution when handling ashes as these can be red hot.
In the event of fire or other danger, switch off the current to
the burner and carry out the necessary actions.
Clean the boiler and clear it of soot when flue gas tempera-
ture rises to approx. 50°C against a newly soot free boiler.
The unit should always have an alternative energy source in
order to reduce dependency.
Use only wooden pellets, which satisfy the requirements found
in industry standard SS 18 71 20, group 1.

container.
Placement of fire grate
The grate should be placed as per the diagrams below. Incor-
rectly positioned grates can extend ignition time, or ignition
may not work at all. The ignition element may also be liable to
damage.
1. Cross section of inner combustion pipe at front edge of grate.
2. Cross section of combustion pipes in their longitudinal direction.
3. Inner wall.
4. Grate.
5. A flip gate prevents pellets from bouncing out of the boiler, and
reduces heat spillage.
6. The grate must lie adjacent to the inner wall and there must be a
small gap at the back edge of the grate.
7. The grate must lie adjacent to the inner combustion pipe.
Safety system
The pellet unit's safety system consists of:
•an overheating guard for boiler temperature.
•temperature delimiter on downpipe.
• a meltable tube, not flammable, between screw feeder and
downpipe.
•a powerful fan with blower control and back pressure control
on boiler.
•photocell for flame monitoring.
•b locking at high ambient temperatures.
The primary functions cannot be accessed by the user and
there are, therefore, no special controls.
The photocell must be kept clean. Please also check that the
tube between the screw feeder and downpipe is intact. The
photocell can be checked in the following way:
• the burner must be live, though the boiler's thermostat
should not be demanding heat.
• remove the photocell from the burner and shine a light on it,
after approx. 15 seconds, the "LOW" indicator should go on.

Gap
Switch off the current to the burner and remove the the plug before
cleaning, servicing, or before the burner is removed from the boiler.
Risk of burn injuries.
Always show caution when handling ashes as these can be red
hot.
Please check very carefully that the grate is in the right place
when replacing.
Soot residue
The flue gas thermometer, provided, is a great help in trying to
establish if it is time to clean and de-soot the boiler.
In order to retain a good efficiency level, the boiler should be
de-sooted and cleaned when the flue gas temperature has
risen by approx. 50°C in comparison to when the pan was first
cleaned of soot.
A useful aid for emptying the boiler and burner of ash is an ash
box, which is attached to a normal vacuum cleaner.
Cleaning the burner
For optimum function, the burner should be regularly cleaned
at the same time as the boiler is de-sooted, the ash which
is inside the the burner's inner combustion pipes must be
extracted. If the burner hatch can be opened whilst the the
burner is mounted in place, this is a simple undertaking.
Otherwise, the burner has to be removed from the hatch. By
opening the quick release fasteners, the burner, and its in-
ner combustion pipes, can be separated from the outer shell.
First, release the quick release connection on the tube from
the screw feeder.
Always allow the burner to burn out before commencing
cleaning, otherwise burning pellets may still be found in the
burner
Clean the inner combustion pipes with the ash rake provided.
Then remove the grate and rake out the ashes that may be
found there.
On every second or third pass, based on the soot residue
found in the boiler, the ash and material gathered between
the burner's inner and outer combustion pipes should be re-
moved. Here, the burner, and its inner combustion pipe, has to
be separated from the outer combustion pipe.
If the the burner is running at
low output, this increases the
need to clean the inner com-
bustion pipe of ash to twice
a week.
The grate should be brushed
clean using a steel brush.
When cleaning, take care not
to push out the gills on the
grate so that airflow is re-
duced. The opening must be
at least 1 mm.
Please check when reas-
sembling the burner against
the outer combustion pipe
that the sealant material is
sitting correctly and that it
presents a seal against the outer combustion pipe. If the seal
is damaged, the inner combustion pipe may also be liable to
damage.
Dust, which collects in and upon the components inside the
the burner's cover, should be blown carefully away using pres-
sured air, or can be brushed away with a soft brush
Ash and soot
Ash and soot should be kept in a metal bin with a close
fitting lid. Ash embers can remain alive for several days, so
ash residue should therefore be placed in a non inflammable

Troubleshooting
Alarm reset
Switch off the current to the burner for approx. 10 seconds.
Current must always be switched off when addressing a fault
in the burner. When work is complete, the alarm is automati-
cally reset when the burner goes live again.
Troubleshooting
For all types of fault, the burner's basic functions must be be
checked first:
•Is the operation light on, the burner's main switch in on position?
•Is the burner's fuse intact?
•is the burner receiving a current?
•Are all control units, thermostat etc, properly set and adjusted?
•Are all safety devices, overheating guards, safety gates etc, function-
ing normally?
•Is the burner receiving pellets?
If the cause of the fault is not listed above, all of the burner's
functions must be checked. If the burner is in alarm mode, the
alarm indicator lights up and this has to be reset.
Observe the burner's behaviour. When troubleshooting, a meas-
uring instrument can be very useful.
Other reasons for faults
Common circumstances which give rise to problems:
• the screw feeder's slope from the horizontal plane is not 40°±5°.
• pellets do not comply with standard.
• draught >20Pa.
• no contraflow hatch.
• large area in waste gas flue.
• irregular fuel feed due to screw feeder not going far enough.
• incorrect placement of fire grate.

Risk of snaring.
Do not place your hands or objects inside the screw feeder.
The feeder cable should be decoupled from the the burner
before any adjustments are made to the screw feeder.
