Ariterm Lilla Frö pellet stove Installation and operating instructions
The Lilla Frö pellet stove is designed to work as a primary heat source in a house. This high-efficiency stove can replace up to 80% of the heating in a normal home that uses electricity as its primary heating source. With its automatic operation, it requires an electrical power supply and during a power failure, it requires a reserve power source from an uninterruptible power supply (UPS) or a petrol driven generator. It can also be installed without a traditional chimney using KMP Draft.

Care and maintenance summary
We recommend that you follow the care and maintenance instructions in order to obtain the best possible results from your stove.
• The stove needs air in order to function, never close the supply air vent to the house.
(This is not an issue for those who chose a solution with KMP Draft; this ensures that the stove has air).
• Your engineer has adjusted the amount of fuel used in the stove’s starting dose. Use the menu system to change the starting dose and output, see section 1.6 in the manual.
• We recommend removing the ash daily during the firing season, or each time pellets are filled.
Remove ash through the door using the handle supplied. Lift out the burner from the burner housing and remove any ash from the ash box (unburned pellets must not be emptied into the ash box, there is a risk of them starting to smoulder).
• After a period of use, the glass in the door becomes coated with soot and eventually becomes opaque. Therefore, it should be cleaned on the inside using kitchen roll moistened with normal tap water. We recommend that this is done every time the pellet hopper is refilled.
Wait until the glass has cooled before you start cleaning!
• Vacuum the ash from the ash box once between visits from the chimney sweep, which is normally twice a year. The ash hatch is located behind the filler hatch and it can be lifted straight up after the plastic knob has been screwed loose.
• The stove’s tubes are swept automatically using the sweeping unit (patent pending) every time the hatch is opened, and they normally do not need any further sweeping.
• Vacuum the interior of the stove once a year to prevent the stove’ s fans from becoming jammed by the soot that gets into the stove. To access the fan first pull out the plug then remove one of the stove sides.
• If you have installed KMP Draft, ash must be removed from it at least once every firing season.
NOTE! When you start your stove for the first time there may be a slight smell of paint, this is because the paint on the stove body must cure fully before one can obtain odour free operation.

1 Product description
1.1 General
The Lilla Frö stove has been developed to work as a primary heat source. The stove’s high level of efficiency, in combination with automatic operation, means that the stove replaces up to 80 % of the heating in a normal family house with electricity as heating source. The stove is designed for firing with wood pellets and requires an electrical power supply. In event of a power cut, the stove requires a reserve power source from an uninterruptible power supply
(UPS) or a petrol driven generator in order to function.
The integrated convection fan distributes the hot air around the house, for best effect the stove should be centrally located on the lower floor of the house. The room temperature is easily set from the control panel. During thermostat operation the stove automatically ignites and extinguishes the stove when the set temperature is reached.
It is filled with pellets by opening the hatch under the stove’s top panel. The spacious hopper means that the stove only needs to be refilled a maximum of twice a day. The filler hatches and door are equipped with safety switches. Two safety thermostats are mounted together with the switches in a safety coil to prevent overheating and back-fire.
Lilla Frö can be installed without a traditional chimney if your home does not have one.
The solution that makes this possible is called KMP Drag, which is a patent-pending, fan controlled, flue gas duct that goes straight out through the wall.
The stove must not be used as an incinerator and must only be fired using wood pellets acc. to EN 14961.
NOTE! The stove’s surfaces on and around the glass become extremely hot.

1.2 Components
The top panel (1) is opened by lifting the front edge. Under this are the ash hatch (2) and the filler hatch (17) for the pellet hopper.
The front (5) is opened to reach the door (7). The door is unlocked with the enclosed handle and it opens forwards, towards the floor. The burner housing (8) is located in the hearth and is accessible when the door has been opened. It is installed with four screws on the rear of the stove body. The burner (9) sits loose in the burner housing. The firing element (10) is located in the burner housing behind the burner.
The firing element gives off the heat required to ignite the fuel. The flame sensor (11) is beside the ignition unit and indicates whether there is flame in the burner. The ash box
(12) is inserted in the bottom of the hearth, under the burner housing. It can be removed when the door has been opened.
The combustion fan (13) is placed on the rear of the burner housing and provides the burner with air for combustion. If the stove is connected to the flue Drag, the fan is replaced by a hose, which is connected to the wall lead-in. The control circuit board (15) is placed inside the stove and it is powered by an electronic transformer that supplies
12V-voltage to the electronics and control and sensors. The hot air fan (16) is located inside the stove and sucks air from the rear of the stove, which is then heated up in the combustion chamber and smoke tubes (4) and expelled through holes, partly in the back plate and partly in the front.
The pellet hopper (17) is filled through the filler hatch (18). The hatch is locked with a knob. The pellet feeder (19) sits in the bottom of the pellet hopper and it consists of a slowly rotating screw. The patented design means that pellets cannot stick in the feeder.
Safety thermostats (20) are mounted on the pellet hopper’s right side (trip at 85˚C) and the ash box (trips at 204˚C).
The stove must not be modified and only spare parts recommended by the manufacturer may be used.

1.5 Safety system
The K6 stove is equipped with five independent safety systems.
1. The feeder releases pellets into a chute, which means that the fuel cannot burn back and spread the fire into the hopper.
2. The pellet hopper is equipped with a tight fitting filler hatch. The hatch must be closed and locked during use, as soon as the hatch is opened the fuel feed is interrupted and a warning text is shown on the display.
3. Two thermostats are located as shown in section 1.2 Components (fig 1). If the maximum permitted temperature is exceeded the feeder stops, the stove switches itself off and the display shows “Operational stoppage”. The alarm must be confirmed by pressing a button.
Do not forget to rectify the cause of the operational stoppage.
4. A flame sensor is located in the burner (fig 1).If the flame goes out or pellets are fed in faster than they can be burnt and no flame is indicated for approx 3.5 minutes, the stove switches itself off, and an exclamation mark illuminates while “operational stoppage” scrolls through the display.
5. The door is equipped with a safety switch. The door must be closed during operation, if it is opened the fuel feed is interrupted.
The safety switches are tested by unlocking the filler hatch during use or start-up.
The pellet feeder should then stop.
1.6 Control system settings
The settings are made in the control panel in a menu system. Before entering the menu the panel is in display mode. Enter the menu by pressing the dial.
If the menu is inactive for a long time the panel returns to display mode. The menu system consists of a main menu and several sub-menus “Usermenu” and “Settings”.

2 Installation
2.1 Positioning
The installation must meet all applicable European standards, local and national requirements.
The stove should be located in a central position on the lower floor of the house to facilitate heat spread. Consideration must be made of how the chimney is arranged, contact the dealer. Try to avoid placing it in a corner, but if it cannot be avoided observe the minimum distances to the walls according to fig. 7.
The Building regulations contain a number of regulations to prevent fires.
Generally speaking, the regulations are applied if the following is being observed:
• The stove must be placed at least 100 mm from the wall.
• The underlay must be made of non-flammable material, and extend at least 300 mm to the front and 100 mm to the side of the stove. If the hearth surface is made of steel it must be at least 0.7 mm thick.
• Flammable material must not be exposed to temperatures exceeding 80˚C.
Otherwise the stove must have at least 1 m free space on one side in order to allow service.
The weight of the stove is so low that no extra demands are made on the joists etc.
2.2 Chimney
The regulations regarding chimneys can be found in the Building regulations.
The most important regulations are:
• The highest surface temperature of the flue including insulation and surrounding shaft may be 100˚C when the stove is running at full output. The surface temperature of adjacent building parts may not exceed 80˚C.
• Minimum diameter (round duct) or side (rectangular duct) should be 80 mm.
• The smoke ducts must be made of non-flammable material of sufficient durability and with sufficient resistance to temperature variations, climate effects, corrosive smoke gases and slag and use of sweeping tools etc.
• It must be possible to clean the flue. If fallen ash cannot be removed via the stove’s cleaning hatch another cleaning hatch must be arranged. The cleaning hatch must not be located in a room other than the one in which the stove is located.
• Connection to the chimney must be via a steel flue pipe of at least 2 mm thickness, or minimum 1 mm thickness if stainless steel. The joint is sealed with hard packed glass fibre or elastic sealing compound that can tolerate at least 250˚C.
• All parts of the chimney situated outdoors must be insulated.
• The stove must NOT be connected to divided chimneys or flue gas ducts.
The smoke gases contain water vapour that can condense to water if the temperature is sufficiently low (approx 55˚C) which can cause damage both to the chimney and stove.
If the temperature approx. 1 m below the chimney top is below 60˚C one should install an insert, speak to your engineer or chimney sweep.
In the event of a chimney fire, pull out the plug and call the emergency services.
2.3 Ventilation
There must be at least one air supply ventilator in the room where the stove is located.
If there are other exhaust fans increase the number of supply ventilators until the fans no longer affect the pressure ratio. We also recommend that a chimney fan is installed.
2.4 KMP Draft
Information about installation with KMP Draft instead of a traditional chimney is available in a separate manual. See Draft Wall fan Installation and Operation instructions.

3 Operation and maintenance
The K6 stove is designed for a long service life, motors and other moving parts are of a very high quality. All bearings are lifetime lubricated and the only preventative maintenance that is normally required is sweeping and cleaning.
3.1 Fuel
The K6 stove functions best with Ø6 or 8 mm wood pellets, max length 40 mm. The pellets are supplied in plastic sacks that can be stacked on pallets or other suitable surfaces. Avoid exposing the sacks to moisture or mechanical stresses (vibrations or blows). Careless handling of pellets can easily reduce the fuel to sawdust. The sawdust is fed into the burner with the pellets but can cause poor combustion. Fill the hopper with pellets slowly and without too great a drop. The feeder completely empties the hopper and therefore does not normally require cleaning.
The hopper is filled by opening the hatch above the pellet magazine.
Unlock by turning the locking knob a 1/4 turn clockwise.
The hopper can be filled while the stove is running, but because the feeder switches off when the hatches are opened, you only have a few minutes before the hatch must be locked again. If the hatch is open for longer, the flame is likely to get so low that the stove will switch itself off, after which it must be restarted again after the switch is set to the “OFF” position.
The stove is started by moving the switch to the “ON” or “THERMOSTAT” positions.
Take care not to start the stove with flammable objects on top of, or in the immediate vicinity of, the stove! Shut off is carried out by moving the switch to the “OFF” position.
The stove must not be covered.
3.2 Ash removal
The amount of ash that build up in the burner varies depending partially on how the stove is fired (number of starts and stops, division between full and half speed), and partially on the quality of the pellets. The ash content varies between different pellets, but can also differ between different batches from the same factory. This can only be established through trial and error, but generally the ash layer in the bottom should be a maximum of a centimetre deep. We recommend removing the ash daily during the firing season, or each time pellets are filled.
Remove ash through the door using the handle supplied. Lift out the burner from the burner housing and remove any ash from the ash box (unburned pellets must not be emptied into the ash box, there is a risk of them starting to smoulder). Certain pellets generate a hard cake of cinders, this may need to be broken up using a screwdriver or removed using one’s hands.
Ash from the stove must be stored in a container made of non-flammable material, for example a metal bucket, until it has cooled sufficiently that it can be held in one’s hand.
It can then be thrown away, bear in mind that wood ash contains nutrients that can be beneficial to gardens.
3.3 The glass
During firing the stove door can get so hot that it can cause burn injuries if touched.
After a period of operation the glass in the door becomes coated with ash dust and eventually becomes opaque. It should, therefore, be wiped off from the inside using kitchen roll moistened with normal tap water, we recommend that this is done each time the pellets store is filled. No cleaning agent is usually necessary.
When cleaning the black and stainless steel outer panels, only use water and, where necessary, washing-up liquid.

PELLET STOVE KMP LILLA FRÖ
3.4 Sweeping
The chimney must be swept twice a year. The flue and its connection and the area underneath the cleaning hatch must be cleaned at least once between the chimney sweep’s visits.
1. Open the top panel.
2. Unscrew the knob that locks the ash box.
3. Lift the ash box vertically by both knobs.
4. Vacuum clean the ash from the ash box.
5. Vacuum the horizontal flue all the way to the chimney.
The hole is 50 mm in diameter, sufficiently large for a normal vacuum cleaner hose.
If the flue Drag is installed, the sweeping can be done from the outside.
6. Make sure that the ash hatch is firmly in place after cleaning and tighten the knob properly.
The chimney must be checked for blockages if unused for a prolonged period.
3.5 Hot air fan
Vacuum cleaning of the fans with a brush nozzle should be carried out a couple of times annually after removing the side hatch.
Do not forget to pull the plug out before the side hatch is removed.
1. Open the top panel.
2. Loosen the screw on the top of the side panel.
3. Snap the back of the side panel from the stove’s back plate by prizing back the top and bottom corners of the side panel.
4. Unhook the panel, out - forwards.
NOTE! When vacuuming the hot air fan, be careful not to damage the long and vulnerable fan blades.
The fan bearings can start to whistle after operating for some time in a dusty environment.
Rectify this with a drop of oil on both bearings.
3.6 Operating stoppage
If the stove does not start, check first where the fault is located using the fault-tracing diagram below. If you consider that you have the necessary expertise, rectify the fault as suggested. If not, or if the fault cannot be located, contact your dealer.
After an unsuccessful start attempt or operating stoppage, the burner crucible must always be emptied! If there are unburned pellets in the crucible it must not be emptied into the ash box.

• The hopper is empty.
• One of the MCBs is not switched on.
• One of the safety thermostats has deployed.
• Pellets have jammed in the feeder.
• The feeder does not rotate.
F ill up the pellets.
Ensure that the filler hatch is closed and locked properly. A slight clicking noise should be heard when the safety switch is activated.
Check the fuel volume, and that the hot air fan functions. Wait until the stove has cooled. Reset by pressing the control panel.
Feel inside the chute, in case pellets have jammed there. Empty the hopper. Loosen the panel above the feeder screw and remove any blocked pellets.
Open the filler hatch, press down the safety switch to the right of the filling hole. If the feeder screw does not move (1 turn/min), check whether there is a voltage on the motor’s terminal block, on the hopper’s right side under the insulation.
Fault
Pellets do not ignite (no smoke)
Cause
• The firing element does not work.
• Bad connection.
• Starting dose too small.
Action
Replace firing element.
Check wiring and connections.
Adjust the fuel volume.
The stove stops shortly after starting (exclamation mark in the display)
Water is penetrating the chimney joints or is seen in the form of grey/white smoke.
• Starting dose too small.
• One of the safety thermostats has deployed.
Adjust the fuel volume.
Remove the burner and check that the flame sensor is in the correct position and that the lens is clean.
Clean flue, convection tubes, fans and ensure that the air intake of the stove is not blocked.
• Too low output.
• Too low smoke temperature for the chimney.
Increase the fuel volume.
The smoke temperature in the chimney 1 m below the top must be at least 60˚C.
After an unsuccessful start attempt or operating stoppage, the burner crucible must always be emptied!
