IMPORTANT INFORMATION

The installation and operation information given here is of general nature. National and European standards, local and building regulations as well as fire prevention laws must be observed during the operation of the stove.

General safety instructions for the operation of your stove

• =Thoroughly read the entire manual before starting up your stove and observe the caution notices.
• Your heating unit must not be moved without approved means of transport with sufficient load-bearing capacity.
• Your heating unit is not suitable to be used as a stand or as a ladder.
• Please keep in mind that your stove’s surface  heats  up  considerably during operation. We therefore recommend wearing a safety mitten when operating your stove.
• Make your children aware of this particular danger and keep them at a distance from the heating unit whenever it is in operation.
• Attention – stove varnish is no rust prevention!
• Only burn approved fuels and materials listed in the chapter “Clean Burning”.
• The burning or placing of flammable or explosive materials, such as empty spray cans, etc. into the firebox as well as the storage of such materials in the immediate vicinity of your heating unit is strictly forbidden due the danger of explosion.
• Do not wear loose or flammable clothing when adding fuel to the fire.
• Placing non-heat-resistant objects on the heating unit or in the vicinity of the heating unit is forbidden.
• Do not lay laundry onto the stove for drying. Laundry hung up to dry must be kept at a safe distance from the stove because of the danger of fire.
• This stove is tested as a “Zeitbrand- Feuerstätte” (intermittent burning device), which means that a continual operation can only be achieved by a constant putting more wood on fire.
• During the operation of your heating unit it is forbidden to use flammable or explosive materials in the same or an adjacent room to the one in which your heating unit is located.
• The appliance must be operated with the stove door closed.
• The stove door and all fittings for adjusting the stove must be closed, if the appliance is out of use.

Setting up your stove

Required safety distances (Minimum distances –see name plate – in Fig. 2) – towards flammable materials

a – toward the front in the radiated area > 1000 mm b – to the side > 610 mm
c – to the back > 120 mm

Corner installation:
a – toward the front in the radiated area >800 mm b – to the side > 120 mm
d – ceiling > 700 mm

Make sure that the room in which the stove is set up has at least one door or window into the outside or is directly adjacent to such a room. Other fireplaces and extractor hoods must not be operated in the same room as the stove.

Floor load capacity
Make sure that the load capacity of the supporting construction is sufficient to carry the weight of the entire unit, before the heating unit is installed.

Combustion air
Being the user of the stove you must take care of a sufficient combustion air supply. Sealed-up windows and doors may not allow a sufficient combustion air supply or disturb the draught behavior of your stove. Please ensure the additional supply of fresh combustion air if necessary. For details please consult your specialist retailer.
Make sure that the combustion air intakes are not blocked!

Stove pipe connection
For your own safety stringent laws apply for connecting the stove pipes to the chimney. Your professional dealer or distributor knows these laws. Please have your certified retailer carry out the connection of your stove.

CORRECT OPERATION OF YOUR STOVE

Approved fuels
Dry, well cured and natural wood (hardwood preferred), wood briquettes.
Maximum amount of fuel
Maximum amount of fuel to be added: 1,5 kg wood or briquettes. Larger amounts of fuel can lead to overheating and thus damage the stove.

Clean burning
The wood must be dry (relative wood moisture < 15%) and untreated and the right amount of wood must be burned in order to ensure a clean fire that releases only small amounts of emissions.

Startup procedures
During the first 3-4 operations – at nominal heat output – there may be some odour development and the varnish has not yet hardened.

Making a fire
For the correct and safe operation of your stove please pay attention of the chimney developing the necessary feed pressure. This must especially be considered before the initial operation (or e.g. after the summer heating break) and during the mid-season heating periods (e.g. at strong wind, etc.).
If there is not enough feed pressure, please light only some paper or small kindling first, in order to “warm up” the stove and the chimney.

The air inlet must not be covered or closed.

Clean grate, empty ash drawer if necessary (watch out for ambers!)!

Position the lever for the combustion air to the open (“AUF”) position (see fig. 2 and 4).

Place 2-3 logs (approx. 1,0 kg in total) crossways in the combustion chamber (1) with sufficient distance from each other (min. 2 cm), on top of that place some softwood chippings (0,5 kg) (2) and some ignition aid and light (3).
(see fig. 3)

Close the door!
We recommend to let the first load burn down without changing the air lever position.

As soon as no visible flames are left (only embers in the combustion chamber), you can put another load of logs (max. 1,5 kg) in the combustion chamber if desired.

When reloading the stove please repeat the procedure as mentioned under “first lighting”: air lever position on “AUF” (= open), open door carefully, place logs, close door.

After a few minutes, when the logs burn well on all sides (bright, high flames – see fig. 5), you can adjust the heat output with the air lever (lever on max. position “AUF” = maximum heat output), the flames should be yellow and never look blueish or have black tips (otherwise add more air) – see fig. 4. Never close air supply completely during operation. (danger of flash-fire!)

The stove door may be opened only for refuelling or disposing of ashes and is to be closed again afterwards.

Heating in-between seasons
If you heat the stove in between seasons, when the outside temperatures are higher, the flue gases may not be able to escape completely and this may lead to disturbances in the chimney draught, especially if the temperatures are rising suddenly. The stove has to be charged with less wood then and the primary air has to be increased so that the wood can burn down faster (with visible flames) and thus the chimney draught can stabilize.

Chimney fire
A chimney fire may occur, due to scooting and deposits in the chimney, if wrong or humid fuel is used. In case of a chimney fire close all air inlets on the fireplace/chimney immediately and call the fire brigade. Please have an expert inspect your chimney for cracks and air-tightness after the burning out of the chimney.

Keramott numbering = installation instructions

Accessories

You can obtain floor plates of glass or steel or care products from your certified dealer.

IMPORTANT: Have defective parts replaced by your certified dealer. This will guarantee that your stove functions properly and safely.

The fireplace must not be altered. Any alteration to the stove or improper use will lead to a loss of the warranty title!

Maintenance

To clean the glass, please use a specialized product such as Thermohit glass cleaner. Lacquered surfaces are to be cleaned only with a cloth (may be damp). Special cleaning agents should also be used for stainless steel surfaces.
Only gaskets in good order ensure the proper function of your stove!

Cleaning

The stove, flue outlets and smoke pipes should be cleaned and inspected for deposits every year – if necessary more often,
e.g. after the cleaning of the chimney. The chimney also has to be cleaned regularly by the chimneysweeper. Your chimneysweeper will inform you of the necessary inspection intervals. An expert should inspect the stove annually.

SPECIAL FEATURES STILA

Operation with external air supply

The German institute for constructional engineering (DIBT) has given the Stila the general technical approval for operation with exteranl air supply. If the combustion air is being supplied directly to the furnace by an air-tight pipe including closing mechanism from the outside, then the stove may be used in residential property with mechanical ventilation.
If the stove in being used like that, a multiple stove installation on the same chimney is forbidden.
This stove has been approved by the German DIBT.

must be cleaned with Austroflamm glass cleaner from time to time (depending on the frequency of use)
contact your chimney sweep (elongate chimney/draught metering)
incorrect use of the combustion air supply lever| please operate air lever according to user’s instructions (if secondary air is closed, the door glass soots rather fast)
wood logs are too large| keep to the max. fuel quantity according to user’s instruction
operating temperature was not reached| more fuel, use dry wood (< 15 % residual moisture), attend air regulation
stove does not get enough combustion air| chimney draught not sufficient| contact your chimney sweep (elongate chimney/draught metering)
stove is sooted inside| more fuel, use dry wood (< 15 % residual moisture), attend air regulation
stove smells strongly and there is smoke on the outside surface| baking phase of the varnish| there may be some odour development during the first operations
stove is dusty/dirty| cleaning before the heating season starts!
exhaust gas emission while putting more wood on the fire and during operation| chimney draught no sufficient, flue pipe connection leaky| inspect joints and seal up again if necessary
check chimney draught, examine operating – for info video follow: http://www.austroflamm.com/de/Video/index.html
the stove door was opened before the wood has burnt down to embers| put more fuel wood into the combustion chamber only if there are only embers left (no more visible flame)
