ASSEMBLY AND INSTALLATION
INSTRUCTIONS
N.B. To install the stove, use only authorised and
trained personnel, or contact the dealer.
1. Check that the floor can support the total weight
of the stove (140kgs).
2. Refer to the figure that shows the dimensions
of the flue pipe, and allowing for the thickness
of the floor-protection base (if applicable), make
a hole in the chimney to accommodate the
smoke outlet pipe (diameter 80 mm).
3. Connect the stove to the chimney with a
certified steel pipe suitable for this use and seal
it. This appliance must not be connected to a
shared flue.
4. Leave adequate clearance around the stove for
cleaning and servicing. If the appliance is to be
installed in an alcove a minimum of 400mm
clearance is required all round to allow access
for cleaning and servicing. This appliance has
adjustable legs.
HEARTH DIMENSIONS
The hearth should extend 150mm to the rear of the
stove and 150mm to both sides and 30cm to the
front.

Flue Outlet
FLUE - VERTICAL EXTERNAL OR INTERNAL
CHIMNEY
The flue arrangement shown is the best solution for
evacuating smoke, even when the ventilator is off
(no power supply, or lock out flame). Any installation
must comply with current building regulations.
The minimum 2m level difference between the roof
outlet and the T fitting inside or outside the building,
ensures a minimum vacuum inside the stove, thus
preventing smoke issue into the room.
External flues must be insulated: for example by
using double-wall flue pipes.
The figure shows the recommended arrangement
for flue outlets above roof level. In all cases, there
must be a T fitting with inspection plug. The flue
duct must be suitably fastened and fitted with a
chimney pot for rain protection.
SAFETY WARNINGS
This appliance is not suitable for connection to a
shared flue.
The stove must be placed on a non combustible
hearth. If it is to be supported on a combustible floor
surface, it must be supported on a floor-protection
plate of at least the size shown in 3.1. It must be at
least 8mm thick.
The appliance must be connected to a chimney
suitable for solid fuels with a minimum diameter of
100mm and with a minimum length of 2m from the
appliance flue outlet.
For insulating and sealing the pipes, use only heatresistant materials (250° C).
The through-holes in walls or floors must always
have an insulated tube or ventilation passage, so
that it is always possible to disassemble the
chimney components for cleaning and inspection,
and to prevent contact between these components
and wall masonry or inflammable surfaces.
It is useful to have planned inspections of the pipe
bends for periodic maintenance of the flue duct.
The smoke outlet pipe must be protected against
rainwater ingress.

Where it is necessary to have a horizontal length of
pipe, there must be a minimum positive gradient of
3% along its length.
Do not run flue pipe in a totally horizontal plain or in
a reverse gradient.
Do not install the smoke outlet at pavement level,
on public streets, car-parks or anywhere that might
cause annoyance to people and/or animals.
The flue must be installed with the outlet above roof
level complying with current building regulations. A
maximum flue length of 8 metres is allowed. For
each 90° bend or T fitting, reduce the length by one
metre. A minimum flue draught of 10 Pascals is
required.
IMPORTANT: All sections of the flue pipe must be
accessible for inspection, and allow for internal
cleaning, removal or substitution.
Do not place a net or grill over the flue outlet. When
they become dirty they will obstruct the outlet and
cause poor combustion, and the stove may be
blocked with soot.
COMBUSTION AIR
The process of combustion requires oxygen, and
therefore air. When in operation, the stove draws air
from the room in which it is installed; poor
combustion may therefore result if the room is
insufficiently ventilated.
To resolve this problem, a suitable vent hole must
be provided to allow a permanent supply of fresh air
from the outside. The cross-section of the vent must
be 6cm² for each kW of energy consumed at
maximum input therefore the ventilation hole must
have a cross-sectional area of 83cm² if a flue
draught stabiliser is fitted.
If no flue draught stabiliser is fitted the ventilation
requirement is 44cm².
If the stove is located in a room containing another
appliance cooker hood or extractor fan, it is
essential to provide ventilation equivalent to the
sum of the air requirement for all appliances.
The vent must not be placed directly beside the
appliance in order to avoid drawing in air that is too
cold: at certain times of the year when the
appliance is very cold, the stove may be locked out
when you first attempt to light it. If this occurs, the
situation should be considered absolutely normal,
and you can unlock the stove using the switch #4
located on the control panel. Then switch on again.

INITIAL COMMISSIONING
It is vital that the installation of the AGA Fusion
Pellet stove is in accordance to manufacturer’s
instructions.
On commissioning the appliance it is important
that the Auger is filled with pellets prior to firing.
To do this the fire door must be closed:
a) Fill the hopper with 6mm diameter pellets
taking care to keep sawdust in the bag.
b) Turn the power ON to the appliance and press
the power switch ON (located on the back of
the unit).
c) Press and hold button 4 for 4 seconds to turn
the unit ON (this will activate the fan required
to activate the air pressure switch), then repress button 4 for 4 seconds to turn the unit
OFF. Leave the mains power onto the
appliance.
d) Press buttons 5 and 6 together, this will
activate the Auger, hold the buttons until
pellets are seen to enter the burner from the
pellet chute, the Auger should now be loaded.
e) Remove pellets from the burner pot.
The stove has sequence settings which are
factory-set by the manufacturer and these should
not be altered.
However these must be checked during initial
commissioning before firing. To do this press
button 3 a number of times until UT01 shows. If
the lower display shows OFF then you will need to
set the correct day and time (See Page 10).
Day 1 - Monday
Day 2 - Tuesday
Day 3 - Wednesday
Day 4 - Thursday
Day 5 - Friday
Day 6 - Saturday
Day 7 - Sunday
1. Press button 3 until UT04 shows on the upper
display.
2. Press buttons 1 or 2 until A9 shows on the
lower display, then press button 3.
3. The upper display should show Pr 01 and its
setting shows on the lower display. Should its
setting be incorrect, change the setting using
buttons 1 or 2. Once confirmed as correct press
button 3 to check the next setting, Pr O2 etc ...
there are 28 settings in total under A9.
Pr 01 - 18 Pr 02 - 5 Pr 03 - 30 Pr 04 - 2.5
Pr 05 - 1.5 Pr 06 - 1.5 Pr 07 - 2.0 Pr 08 - 2.5

Pr 23 - 10 Pr 24 - 12 Pr 25 - 16 Pr 26 - 22
Pr 27 - 30 Pr 28 - 250
4. It is then necessary to check the settings on C9.
This is reached in exactly the same way, by
pressing buttons 1 or 2 then button 3 when C9 is
reached.
C9 settings are all set to zero.
Pr 56 - 0 Pr 57 - 0 Pr 58 - 0 Pr 59 - 0 Pr 60 - 0
Pr 61 - 0 Pr 62 - 0 Pr 63 - 0 Pr 64 - 0 Pr 65 - 0
5. Repeat the procedure for the D9 settings.
Pr 81 - 2150 Pr 82 - 2200 Pr 83 - 2250 Pr 84 - 2350
Pr 85 - 2550
6. If you pause longer than 60 seconds when
checking these settings you will need to return to
step 1, then go to where you left off.

SAFETY AND CORRECT USE OF THE
APPLIANCE
Before switching on for the first time, read the
following safety instructions.
1. Some parts of the stove become hot (door,
glass, flue, etc.), and contact with these parts
may cause burns.
2. Do not place combustible or inflammable
material beside the stove, and never at less
than 1 metre.
3. Do not store bags of pellets close to the stove.
4. Your stove burns pellets only - it is not an
incinerator. It is forbidden to burn other
materials or household waste as fuel.
5. When loading pellets into the tank, avoid
pouring sawdust along with them. Failure to
follow this instruction may make the appliance
unsafe, and void all warranties.
6. Keep children away from the stove. Do not
open the door when the stove is lit.
7. Do not switch off the electric power supply
while the stove is on. This will cause the smoke
extractor fan to stop, and the burning fuel will
cause smoke to issue into the room if there is
no natural upward draught in the chimney.
8. When the stove is lit for the first time, the
varnish may release fumes, and these may
emit an unpleasant odour. The room must
therefore be ventilated to evacuate these
fumes. The varnish will be fully hardened after
several heating cycles (2-3). On first lighting the
stove may lockout as there is no pellet in the
feed. The display will show ALARM NO FIRE.
The stove has to be switched off and on again
to reset.
9. Periodically ensure that the gaskets between
stove and flue pipe are gas tight.
10. In case of fire switch off the stove, move any
flammable materials away, and call the fire
services.
IN CASE OF CHIMNEY FIRE
Switch off appliance and close all openings into the
stove, watch for ignition of adjacent combustibles
from hot embers or sparks from chimney.
FUEL
WHAT ARE PELLETS?
PELLETS consist of sawdust or real wood scraps
ground and pressed into small cylinders about 6
mm in diameter and 20-30 mm in length.
As fuel, pellets are completely environmentally
friendly, as they are made entirely of natural wood,
without glue or other chemical compounds. Pellets
have a high calorific value (4.7 to 5.3 kW/kg), and
low moisture content.
IMPORTANT: Pellets must be stored in a dry place.
Use only good quality pellets, without sawdust.
IMPORTANT NOTICE: The small quantities of
sawdust normally present at the bottom of the bags
should not be emptied into the tank, but should be
held inside the bag while pouring the pellets
carefully so that the sawdust remains inside.
If sawdust accumulates in the tank, it should be
removed periodically with a vacuum cleaner (with
the door open and disconnecting the power plug
from the electricity supply), to prevent it entering the
loading system and causing serious malfunctions.
IMPORTANT: If, during a loading operation, or for
any other reason, foreign matter is allowed to enter
the tank and then the pellet loader, it may cause
damage to the internal mechanisms.
Besides causing damage, this would cause the
stove to stop. In this case, the manufacturer cannot
accept any liability.
ONLY 6mm DIAMETER PELLET MUST BE USED
DO NOT USE POOR QUALITY PELLETS OR REPROCESSED PELLETS WITH HIGH SAWDUST
CONTENT. THIS TYPE OF PELLET CAN
SERIOUSLY IMPAIR THE FUNCTIONS IN YOUR
STOVE, VOID THE WARRANTY AND
THEREFORE RELEASE THE MANUFACTURER
FROM ALL LIABILITY.
PELLET LOADING
The pellet tank capacity is 25 Kg. To load, lift the
pellet tank lid, and pour in the pellets, taking care to
keep any sawdust inside the bags.
Close the lid when loading is complete.
IMPORTANT: LOADING MUST BE CARRIED
OUT ONLY WHEN THE STOVE IS OFF AND HAS
COOLED DOWN.
When pellets are used up, the stove cannot work
and is therefore locked out, the display shows
“ALARM NO FIRE”.
When refilling with pellet at this point it will take a
little while for the pellet to come through so the fire
may go to lockout again. This is normal and will light
normally once the pellet has started to feed,
probably at the second attempt.

Every 60 minutes the Fusion stove will speed its
flue fan up for 60 seconds, this is to help keep the
glass from staining during operation.
The cleaning LED illuminates on the left hand side
of the display.
The flue fan speeds vary during cleaning,
dependent upon the chosen power setting:
Power setting 1 - 2150rpm
Power setting 2 - 2200rpm
Power setting 3 - 2250rpm
Power setting 4 - 2350rpm
Power setting 5 - 2550rpm
ECO Setting
Should the unit be kept in ECO mode for 250
seconds the Fusion stove will turn itself off. Should
the temperature drop below the temperature setting
and the timer be calling for heating as set by the
user, the stove will restart, after completing its full
shut down cycle.
Operation: (Please refer to diagram on Page 12)
a) To start the stove press button 4 for 4 seconds.
The appliance will then energise the flue fan, the
glow coil LED will light and FAN CAND will show
on the panel.
b) After allowing approximately two minutes for the
glow coil to heat up the auger energises (timed)
to load the pellets and LOAD WOOD appears on
the LED display and the green LED on the right
hand side of the display flashes indicating auger
in operation. This phase will continue until 60°C
is sensed in the flue by the flue thermistor.
At any time it is possible to read what temperature
the flue thermistor is sensing by pressing and
holding button 1. The lower display shows the
temperature, the upper figure shows the fan speed.
c) Once 60°C has been sensed in the flue the stove
enters its stabilisation stage (5 minutes), FIRE
ON is displayed on the LED display, the glow coil
is de-energised and the stove will run at the
chosen power setting.
d) The circulation fan will turn on when 80°C has
been sensed at the flue thermistor, the fan speed
will run as per the chosen settings.
e) If the pellets are not lit within 15 minutes; the
stove displays the message ALARM NO FIRE.
This is normal at first start up if the auger is
empty and has not been loaded as described in
the commissioning instruction.
Switch OFF and ON again to reset, making sure
there are pellets in the hopper.

When using two event programming allow at least
30 minutes between the end of the first event to the
start of the second event.
If the stove is not required to work automatically set
UT01 to OFF. In this case the stove ignores all other
settings and will maintain the set room temperature.
If the remote thermostat is connected this will take
priority for the temperature setting.
When the stove is off, pressing and holding button
1 or 2 will show the heating setting of the stove
when lit. This will either display ECO if the room
temperature is at or above the set temperature or
the heat setting 1-5 as previously set.
If the flue gas temperature rises above 260°C, them
stove goes into economy mode and the message
ECO is displayed. This message is also displayed
when the selected room temperature has been
reached.
11
Switching OFF and shut down
The stove can be switched off in different ways:
1. Manually (putting the On/Off switch on the back
of the stove in the Off position).
2. By actuation of a room thermostat, if this is
connected.
3. By a timer program.
Press button 4 for 4 seconds. OFF will appear in the
display. During shut down the stove will de-energise
the auger which in turn will stop feeding pellets into
the burner, the flue fan and circulation fan will run at
full rate and the stove will go through its cleaning
cycle, the fans will stop when the flue thermistor
drops below 60°C.
Electrical Power Failure
If there is an electrical power failure, when power is
restored, the stove expels any remaining smoke
and resumes the working program from the point at
which it stopped. It can only do this if the electrical
power was lost for a few minutes. If the stove has
cooled down during the power failure, the control
unit puts the stove back into the ignition phase and
re-starts the program from the beginning.

MANAGING ALARMS
An alarm indication may appear in one of the
following cases (the alarm can be cleared by
pressing button 4 “ON OFF”:
- Flue gas temperature probe alarm
If there is a fault in the flue gas temperature probe,
the message “ALARM SOND FUMI” appears and
the ventilator and extractor fan are switched on at
maximum speed.
- Flue gas over-temperature alarm
If the flue gas temperature rises above 280° C, the
message “ALARM HOT TEMP” appears and
ventilator and extractor fan remain lit until the
decrease of flue temperature.
- Ignition failure alarm
- Extractor alarm (if this option is available)
This appears if the initial attempt to ignite has failed,
or if stove temperature is too low for operation,
even after the full ignition period has elapsed. The
message “ALARM NO FIRE” is displayed and the
extractor fan remains lit for a pre-set time until the
stove is completely switched off.
- Pressostat alarm
Incase the exchanger gets dirty or the chimney is
obstructed, the safety pressostat switches the
motor auger off (stops the fuel).
In certain weather conditions, the Pressostat
switch can operate even if there is no
malfunction of the stove. This can be caused by
a low flue draught. This is a normal event. There
is no problem with the stove. If the problem
persists check the flue for gas tightness and
draught.
- Safety thermostat alarm
In case of high stove temperature, the safety
thermostat operates and shows on the display the
following notice: ‘ALARM TERM SICC’. To restart
the stove, wait until cool and reset it as shown in
Fig. 10.

Fig.10
ATTENTION: the thermostat has to be reset by
hand.
The control panel is situated in the lower rear
part of the stove.
N.B. the thermostat does not unlock until the
stove has cooled completely.
If the thermostat reset has been successful, a click
can be heard immediately. Also refer to Safety
Devices Section 4 page 15. Before every new
ignition, verify that the burn pot is completely empty.
If not, clean it immediately.
The alarm signals can be cancelled by
switching off and on the stove with button No.4
situated in the frontal panel of the stove.
Ensure air inlet and flue gas outlet are clear
from obstructions before operation of the stove.
If the flue gas temperature rises above 260°C, the
stove goes into Economy mode and the message
appears on the display.
The message also appears when the
selected room temperature has been reached.
N.B.: Method 1 is used to carry out maintenance or
to switch off the stove permanently at the end of the
cold season. Never switch off the stove while it is in
operation, either by cutting off the current at the
plug or at the switch located on the back of the
stove.
This will cause the smoke extractor fan to stop
immediately, causing smoke to issue into the room
if there is no natural upward draught in the chimney.
After switching off the stove on the front panel,
or using the remote control (if this option is
present), wait for 15 minutes cooling time to
elapse before attempting to start again. The
stove may not re-light if it has not cooled
sufficiently.
During the switch-off phase, the smoke extraction
motor continues to run until the stove is cooled,
then switches off automatically. Similarly, the room
air ventilator continues running until the stove has
cooled (the ventilator may switch off and then on
again if there is still some heat in the stove).
SAFETY DEVICES
1. Flue Gas Extraction Motor Failure
If the flue gas extractor stops, a pressure switch
immediately stops the pellet supply.
2. Flue Gas Outlet Safety Device
If the flue gas outlet is obstructed, the pressure
switch prevents fuel from entering the burn pot.
3. Pellet Loading Gear Motor Failure or
Blockage
If the gear motor stops, the stove continues to
operate until it starts to cool down. The system will
attempt to start up the stove, and if the fault persists
the stove will stop completely and lock out.
4. Hot Air Distribution Ventilator Failure
When the temperature at the end of the loader
reaches 105°C, a safety thermostat stops the gear
motor, causing the stove to switch off.
If the thermostat is activated, it must be reset using
the special control (protected by a screw plug) on
the back of the stove under the main switch and
protection fuse.
If the thermostat is actuated again and causes
the stove to stop, contact your service engineer.
5. Temporary Electrical Power Failure
If there is a temporary power failure while the stove
is in operation, the appliance will come on again
automatically. If the power failure is longer lasting,
the smoke extractor stops running and the stove
may therefore emit smoke into the room.
6. Electrical Safety
The stove is protected by a main fuse located on
the rear panel.
CLEANING OF THE STOVE
IMPORTANT: before starting to clean the stove,
check that it is switched off and completely cooled
and that the electrical power supply is
disconnected.
ASHPAN AND BURN POT
WARNING: Do not vacuum hot cinders as they
may cause a fire in the cleaner.
The burn pot must be cleaned every day. Pull it out
manually by lifting, and empty the accumulated ash.
When re-inserting the burn pot, check that it is the
right way round, with the hole for the igniter plug
facing towards the inside of the stove.
Every two or three days, clear the grid at the bottom
of the combustion chamber, take out the drawer,
empty it and replace in the correct position. Finish
off cleaning the inside of the chamber using a
vacuum cleaner. We recommend emptying the
lower ashpan periodically, as described in the
following paragraphs. It may be necessary to
vacuum the small chamber beneath the burn pot.
IMPORTANT: All cleaning and maintenance
operations must be carried out when the stove is
cold. These cleaning operations ensure that the
appliance continues to work efficiently and
correctly. The required frequency of cleaning
operations depends very much on the quality of the
pellets used. We recommend using only tested,
good quality pellets.
After the cold season has ended, the exchanger
must be cleaned. This operation may be required
more often, depending on the pellet quality, but this
should not be considered a sign that the stove is not
functioning correctly.
15
We suggest you carry out this operation after the
cold season has finished.
CLEANING THE FLUE
Whenever this is found to be necessary (and at
least once a year) vacuum and clean all flue ducts
to prevent the build up of particulate matter. It is
important not to obstruct the passage of the flue
gasses.
IMPORTANT: Ensure that the flue pipe gaskets are
gas tight. Where they are not in good condition
replace them immediately. Do not use flexible flue
pipe.
FAILURE TO CLEAN THE FLUE MAY AFFECT
THE SAFE OPERATION OF THE STOVE.
END OF SEASON
We advise using up all pellets remaining in the tank
in order to prevent condensation from forming and
thus clogging and blocking the feeder motor.
Pellets and sawdust remaining at the bottom of the
tank should be removed using a vacuum cleaner. If
there are substantial amounts of sawdust, we
recommend checking the quality of the pellets used
to fuel the stove.
This operation is carried out with the stove off and
cool, and the power supply plug disconnected.
CAUTION: Do not vacuum hot cinders as they
may cause a fire in the vacuum cleaner.
GLASS
The glass will self clean when there is sufficient
heat generated by the burning fuel. If a build-up of
deposits occur on the glass it may be due to draft
conditions, poor quality fuel or very low burning for
a long time. It is best to clean the glass when it is
thoroughly cooled. A deposit of ash will usually wipe
away with a dry cloth.
PERIODIC CLEANING OF THE STOVE AND
HEAT EXCHANGER CLEANING
The stove and heat exchanger must be cleaned
periodically, and exclusively by authorised
personnel.
For seasonal stove cleaning, remove the panel
below the door by pulling it outwards. Loosen the 4
screws which fasten the access cover to the
combustion chamber and using a vacuum cleaner,
clean the inside part being careful to vacuum in the
internal corners. After cleaning, reposition the cover
(replacing the old seal with a new one), and fit the
below-the-door cover back on by simply fastening it
onto the combustion chamber.

CLEANING THE ASHPAN
Open the panel, remove the ashpan, empty it and
re-insert correctly. This operation is usually carried
out once per week, and more often if required.

ANNUAL SERVICING
When conducting the annual service it is advisable
to have the main flue and chimney system swept
and cleaned at the same time.
Isolate the electrical supply to the stove and ensure
that the unit is cold.
Remove the top access panel and essence bowl
and clean out the top airway. See Fig. 11.
Lift out the ashpan and burn pot.
Unfasten and lift out the firebox lining (3 screws).
See Fig. 13.
Thoroughly brush the heat exchanger to remove
deposits and clean out the firebox.

PROBLEMS - CAUSES - SOLUTIONS
18
PROBLEM / CAUSE SOLUTION
Problem Pellet loader blocked
Causes Poor quality pellets, sawdust included accidentally or pellet stuck and obstructing the
feeder slide to the burner, possibly causing the loading auger to become blocked.
Solutions The problem can often be resolved without calling technical support, simply by
inserting a flexible steel rod inside the pellet loading tube once the stove is off and
has cooled. In this way, the blocked pellet can be made to fall into the burn pot, thus
unblocking the auger. This operation is carried out with the stove off and the power
supply plug disconnected.
Problem While the stove is in operation, the pellet loading indicator light comes on, but no
pellets fall into the burn pot.
Cause * Air exchanger ventilator dirty
* Air exchanger ventilator broken
* Stove overheating and safety thermostat was activated
* Flue obstructed or draught diverter grill clogged
Solution * Call technical support service
* Call technical support service
* Call technical support service
* Clean the whole flue - remove draught diverter and grill
If the problem cannot be resolved, please contact the Installer.
