OPERATING INSTRUCTIONS

PELLET STOVE

EKERUM / NEPTUNI

PELLET STOVE KMP EKERUM / NEPTUNI

Important points to note!

In order for the stove to function properly, the following rules must be followed.

• The stove needs air in order to function, never close the supply air vent to the house.

Note that there must be at least one air supply ventilator in the room where the stove is located.

• The room temperature must exceed 5˚C for the thermostat to work.

• Your installer must adjust the stove in connection with commissioning and fill in the values in the warranty/proof of installation at the end of these user instructions.

• The store should be emptied periodically and the sawdust removed using a vacuum cleaner.

Also test the safety switch by unlocking one of the filler hatches or the door during operation or start-up. The pellet feeder should then be stopped.

• 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 operation the glass in the door becomes coated with ash dust and eventually becomes opaque. It should 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.

(Wait until the glass has cooled). If the pane of glass becomes black and/or difficult to clean, see section 3.6.1.

• Vacuum under the top panel’s soot hatch once between visits by the chimney sweep, the sweep normally comes twice a year.

• Sweep your stove once a week during the firing season. Sweeping is easily done by releasing and pulling the soot rakes backwards and forwards a few times. Slide them in and secure them again.

• Vacuum the inside of the stove annually to keep the fans clean. See section 3.5.

• 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 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 the event of a power failure, the stove requires power from another power source (optional extra).

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 thermostatic operation the stove is ignited and extinguished automatically.

Pellets are filled through two hatches on the top of the stove. The filler hatches and door are equipped with safety switches. Three safety thermostats are mounted together with the switches in a safety coil to prevent overheating.

Connection to the chimney can be either upwards or to the reverse.

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 Komponenter

The top (1) lies loose on top of the stove steered by four bearings. The top is lifted to access the cleaning hatch (2). The htch is opened by removing the four screws, one can then sweep the flue (3) and the smoke tubes (4). The flue can easily be turned through 90˚, which makes it possible to connect it to the chimney vertically or horizontally.

Top (1)

The front (5) can be opened. This is how one accesses the soot scrapers (6). These (four per handle) can be slid forwards and backwards, and scrape off the soot between the smoke tubes. The door (7) is opened with the handle supplied and can be swung up on its two adjustable hinges. The burner housing (7) 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 (8) sits loose in the burner housing. The firing element (9) is located in the burner housing behind the burner. It is the firing element that gives off the heat required to ignite the pellets. The flame sensor (10) is beside the ignition unit and indicates if there is flame in the burner or not. The ash box (11) is inset in the bottom of the hearth under the burner housing. It can be removed when the door has been opened.

The combustion fan (12) is placed on the rear of the burner housing and provides the burner with air for combustion. The control circuit board (14) is placed inside the stove and contains a transformer for 12V-voltage to the electronics and control and supervision. The hot air fan

(15) is located inside the stove and sucks air from the rear of the stove, which is then heated up in the smoke tubes and expelled through the holes in the front.

The pellet hopper (16) has space for 38 litres of pellets, and is filled through the top.

The pellet feeder (17) is below the pellet hopper and consists of a rotating cylinder with a spiral spring that slowly turns at the bottom of the hopper and prevents blockages.

The patented design means that pellets cannot stick in the feeder. Safety thermostats (18) are located on the:

1. fall pipe from the pellet feeder (85˚C),

2. the pellet feeder front wall (85˚C) and

3. the flue (204˚C)

The stove must not be modified and only spare parts recommended by the manufacturer may be used.

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.

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.

To facilitate servicing and cleaning, leave space on each side of the stove.

The weight of the stove is so low that no extra demands are made on the joists etc.

Any existing chimney

2.2 Chimney

The regulations regarding chimneys can be found in the Building regulations.

Observe the following:

• 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.

The temperature 1 m below the chimney top must be at least 60˚C.

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.

2.5 Electrical connection

The back of the stove is equipped with a

1.5 m long cable with plug, which must be connected to a 230 V 50 Hz, earthed, mains supply. The internal wiring diagram is shown in fig. 8.

NOTE! If the connection cable is damaged it must be replaced by one of the same type, contact the dealer.

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 stove must be lit with wood pellets, 6 or 8 mm, class 1 according to Swedish standard.

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 them to sawdust, which can cause feed and combustion problems. Fill the hopper with pellets slowly and without too great a drop.

The store should be emptied periodically and the sawdust removed using a vacuum cleaner.

The hopper is filled by opening the hatches above the pellet magazine.

The different stove models have different types of hatches. Where there is a knob the hatch is opened by turning the knob a 1/4 turn anti-clockwise. To fully fill the magazine one has to open the other hatch. 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.

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. 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

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.

If the pane of glass becomes black and/or difficult to clean, see section 3.6.1.

When cleaning the black painted metal components only water and in certain cases washing up liquid should be used.

3.4 Sweeping

The chimney must be swept twice a year.

Remove the cleaning hatch, under the top plate / stone

(4 x Allen screws).

The flue and its connection and the area underneath the cleaning hatch must be cleaned at least once between the chimney sweep’s visits. Sweeping of the stove is carried out once a week during the firing season using the integrated soot rakes.

They are located behind the front panel and must be pulled backwards and forwards a couple of times each, starting from above.

To prevent ash falling onto the floor, move the ash box before sweeping, as follows.

Measurement hole

3. Lift the ash box up and...

Remove the soot rakes as follows:

1. The silicon seal seals against the stove body.

2. Slacken off the nut a couple of turns.

3. Press the soot rake upwards or downwards.

4. Pull the soot rakes (in pairs) straight out.

5. The soot rakes are sealed in reverse order.

The chimney must be checked for blockages if unused for a prolonged period.

4 ...slide it in as far as possible. You can now pull the soot rakes and allow the ash to drop down into the ash box.

1. Lift out the ash box and turn it with the angled panel facing inward.

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.

The side hatch is secured using two panel screws that are visible when the hatches above the pellet magazine been lifted. After the screws have been removed the upper section of the side hatch is pulled straight out and hooked onto the side member.

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!
