IMPORTANT NOTE
If the device is not installed correctly, it will not provide the excellent service for which it has been designed. Please, read these instructions in full and trust the work to a specialist.
The surface of your device is protected by a coat of special anti-heat paint that resists high temperatures. When lighting the fireplace for the first few times, the said paint may emit some fumes.
This is normal and is due to the evaporation of certain components of the paint while it adapts to the heat. We, therefore, recommend ventilating the room until this phenomenon ceases to appear.

INTRODUCTION

IMPORTANT! All local regulations, including those that refer to national or European regulations, must be applied when installing this device.
The way the STILKAMIN fireplace is installed will decisively affect safety issues and its correct operation.
It is important to install the fireplace correctly. For the correct installation of the Stilkamin and chimney, we recommend the installation be performed by a professional.
Hergom heating devices are very high level products of the greatest technical quality.
This series of products has been especially conceived with the reduction of gas values in mind, reducing at the same time fuel consumption and achieving the highest performance levels. The great easiness of use and effective fuel consumption make these  fireplaces a good heating source able to create, at the same time, a warm and homely atmosphere.
The original Hergom fireplaces feature a nameplate indicating: model, thermal capacity and Hergom registration number.
The owner or the authorized user must keep technical documentation at hand and show it to authorities or chimneysweeps, if required to do

BEFORE INSTALLATION

Before installing a fireplace it is important to carry out an inspection to decide where to place it andconsider the following aspects: • Volume to heatupin sq.m.

• Thermal insulation of the room.

• Consider the roof, thermal insulation of thehouse, double glazing, etc.

• Geographical position of the house, internal/external temperature variation.

• Check whether the flue (if it exists) is completeand straight; points of contact between fumesand inflammable material.

• The draft regulator is compulsory if the steelflue is higher than five meters.

• It is compulsory to insulate the hood.

• External air inlet dimensioning

• It is advisable to use good firewood as fuel to get the best out of the new fireplace.

• Floor capacity: please check whether the floor under the fireplace is capable of supporting the weight.

• To connect the fume outlet pipe to the flue it is advisable to call a specialized technician to avoid gas leaks or fire hazards.

• In case of bad atmospheric conditions (thermal conversion), it is very important to check smoke leakage, combustion gas and draft conditions.
  In case of combustion gas leaks, let the fire go out, check that all air inlets are free and that the flue is clean and free from obstacles. In case of any doubt, please call the chimneysweep service, since a draft problem may be related to the conditions of the  flue.

• Before adding more fuel, please gather embers to form an even layer.

• The use of wet fuel or an excessively low gas operation may lead to inflammable materials building-up in the flue, e.g. soot and tar, that after a certain time may lead to the risk of fire.
  In this case close all air inlets and covers.
  Immediately call the fire brigade and make sure all neighbours are safe.

• When adding fuel with high flames, avoid opening the door too fast in order to prevent the flames coming out.

FUEL

Importance of the fuel
Firewood (oak, beech, ash-tree) is the recommend fuel; it is also possible to use compressed wood logs or lignite blocks. The use of waste fuels, rubbish or plastic is forbidden. The use of resinous wood (firtree and pine-tree) is not recommended, since it requires  a more frequent mechanical cleaning of the flue.
Dry wood with less than 20% humidity should be used, since the combustion of wet wood could lead to a soot build-up in the flue and negatively affect the draft of the compact fireplace. Alternative fuels to firewood: lignite blocks, compressed wood logs.

Lignite blocks produce a lot of ashes; therefore the fireplace needs cleaning more frequently. Logs are very good, but do not guarantee endurance. Use only dry material. Burning waste of any kind (especially plastic) damages the compact fireplace and the flue,  and furthermore it is prohibited by the law on toxic substance emissions.

Quantity of fuel
Avoid introducing an excessive quantity of fuel and reaching overheating values that exceed those indicated for the design. The fireplace may be damaged.

• Use small pieces of firewood
• Create a bed of embers
• To avoid the accumulation of dirt on the glass, leave the door a bit open during the first few minutes. This allows any condensation that forms at the beginning to evaporate without accumulating on the glass.

Control of the power of the fireplace is achieved through air inlets. Since fireplace performance also depends on flue draft, openings have to be controlled according to your personal experience.

• Responding to modern demands also implies assuming a number of responsibilities.
  Respecting nature is one of the most important of these requirements. Our products are always the most up-to-date solutions in terms of technological development. This is the fundamental premise for a clean, efficient and irreproachable operation of our  fireplaces.

OMBUSTION

CLEAN COMBUSTION
The fundamental premises for clean combustioninclude:
Wood has to be dry and non-treated – indicativevalue: 15% relative humidity, wood stored in a dry and well ventilated place for at least 2-3 years. Afireplace is not a “waste disposal installation”.
Combustion of waste and unsuitable material, suchas plastic, treated wood, etc. leads to poorcombustion and cancellation of the warranty!Further consequences include damaging anddirtying the device, the flue and the environment.
Too much wood causes overheating: the material is excessively stressed and the fireplace produces negative values of combustion gas.
Too little wood or excessively large logs do not allow the fireplace to reach the best operational temperature. In this case combustion gas values are negative too.
Warning: Only compressed wooden logs, dry
firewood and lignite blocks can be burnt in this fireplace. It is not possible to burn plastic, carpentry treated wood (e.g.: fossil coal blocks or textiles). Using the fireplace with a fuel different from that indicated in the manual will render any manufacturer warranty void.
Combustion inside the fireplace is possible thanks to the combination of the inflow and outflow of air.
Air is the element that controls the fuel. Important:
Use the supplied glove to control the primary and secondary air inlets.
Primary air
Completely opening and then closing the primary air intake allows the combustion to proceed by inertia and heat for a few hours.
Secondary air
During operation it is advisable to keep the secondary air intake always open. In this way combustion quality improves; you avoid useless environment contamination and the glass remains clean, furthermore it helps avoiding soot build-up in the fireplace.
You should not continuously supply firewood to the fireplace because in this way you interrupt combustion transformation phases and performance decreases.
First phase: loss of humidity and combustion of gas substances.
Second phase : transformation of firewood into coal, increase of heating value and weight loss. Third phase: maximum combustion performance.
Fourth phase: slow combustion and progressive power decrease.
Clean firewood combustion is a process similar to natural decomposition, which means that the CO2 (carbon dioxide) being freed does not increase or alter the original concentration of CO2 in the atmosphere.

FLUE

The existing duct or the one to be built must comply with the existing regulations.

Existing duct

• Make sure that it is well sealed.
• Make sure that it is not connected to another fireplace.
• Make sure that the chimneypot is in good conditions and that the height and diameter are correct.

Building of a metal duct
The material to be used is AISI 316 double-walled stainless steel, with a 4/10 minimum thickness (the best value would be 1 mm), installed according to the rules of the manufacturer. Building a refractory material duct This duct is built with three concentric  layers, each one with a specific function:

• The first layer of refractory material guaranteesthe waterproof nature of the product,airtightness and resistance to corrosion andheat.
• The second intermediate layer, apart from theinsulating function, provides for longitudinaland transverse expansion of the refractorymaterial with respect to the external wall.
• The third external layer performs insulating,protecting, guiding and containing functionstypical of refractory material.

This kind of flue is the optimal solution in terms of functionality and endurance in time.

Chimney
The chimney will be rainproof.
The thermal resistance of chimney walls should be at least 0.43 m2kw.
The chimney must extend 1.20 m over the ridge of the roof.

AIR INLET

Thermal insulation of the duct
The passage of the duct through a wall of an inhabited room shall be isolated with fireproof material in order to avoid fire; the minimum distance between the duct and all combustible elements (beams, wooden floors, etc.) will exceed 16 cm.

• It should be placed directly outside or inside a ventilated room, with the right dimension and with the protection of a grid.
• Insulation of the breast wall: insulation is fundamental for light structures, and it is also recommended to avoid loss of heat, thus achieving better thermal efficiency.
• Lifting of the compact fireplace: it is possible up to the height indicated in the design using, for example, Gasbeton ® blocks with the suitable shape.
• Place the marble/stone covering: with the right shape according to the design. Provide a stable support at least on three points or, if it is  overhanging, provide suitable hidden metal supports. The width of the marble/stone top in front of the fireplace  should be more than 30 cm if the floor is made of wood, fitted carpet or any other inflammable material.
• If there is a wooden lintel, it should be protected.
• It is compulsory to build the hood with insulating and fireproof materials. The hood is generally made of plasterboard; to avoid overheating it is necessary to create a ventilation system in the hood through grids, placed in the correct places, to allow the air  to circulate; grids, however, have to be placed at the highest point, but never less than 30 cm from the ceiling with grids with a surface of 600 cm2.

Optimum usage
Do not force the fireplace when used for the first times; during the first few days use the equipment at 50% in order for its components to expand and settle evenly. Always use dry firewood with a maximum humidity of 15%; always charge ¾ big pieces separated  in time, avoid continuously opening the door to add small pieces of wood because this increases firewood consumption; control combustion by means of the primary air inlet.
Notes on fuels
Allowed: firewood, lignite, compressed logs. Do not burn: cardboard, wooden pallets, plastic, alcohol, gas oil or other flammable liquids.

INSTALLATION

Connection to the flue

• It is advisable for an expert to connect the fireplace to the flue.
• The fireplace, the flue and the connection tubes are to be placed in such a way as to allow easy cleaning of the equipment. The installation shall be carried out according to existing safety and construction rules. For further information, please contact your  chimneysweep service for any necessary advice.

The first heating of the compact fireplace should be performed in agreement with the installer. If possible, in his presence and at least 4 weeks after installation. It is important that the lining of the fireplace be completely dry, that means that at the beginning fire  has to be kept low.
During the first uses, in some cases, fumes may escape outside the fireplace; this is due to the polymeric settling of the siliconic paint that has been used. If this happens to your fireplace, we recommend ventilating the room and continue introducing firewood  slowly until fumes stop coming out.

LIGHTING
If the fireplace and the flue are still cold, or there is low atmospheric pressure, we recommend lighting some papers at the beginning to heat up the equipment and decrease humidity.
Do not use enamel or magazine paper, since it does not burn well and releases toxic substances from the inks used in the printing process.
Never use gasoline, alcohol and other highly inflammable substances, use only lighting blocks.
Small pieces of firewood allow for a faster combustion if compared to bigger pieces. In the compact fireplaces with ventilation, the switch has to be adjusted according to different needs.
Combustion residues includefirewood mineral elements (approx. 1%). This ash, since it is a natural product, is a wonderful fertilizer for all the plants in the garden.
Warning: the ash may include residues of burning embers. Therefore, only place ash in heatresistant

MAINTENANCE AND CLEANING

containers.
All maintenance and cleaning work should be done only when the chimney has completely cooled down.
If you use poor fuel the number of cleaning
operations may increase, both in number and in frequency.

• Ceramic glass could be cleaned with a suitable detergent that your reseller can provide. If the glass gets excessively dirty with soot, the cause could be the use of wet firewood.
• Visible metal surfaces should only be cleaned with a water dampened cloth. For any  additional touching-up please use the original paint, that your reseller will provide.
• Regularly use a vacuum cleaner to eliminate dust in convection air inlets in order to eliminate obstructions. Before lighting the fireplace for the new season after a long inactive period, it is advisable to clean the fireplace thoroughly to avoid irritating  smells.
• The flue should be cleaned at least every 1 or 2 years by trained personnel.

Before laying the lining
Check that the vertical movement of the door is working correctly

Loading firewood
Pull-up the door using the vertical opening handleand lifting it up. Use a thermal glove to carry out this operation. After charging the necessary firewood, completely close the door; do not operate the fireplace with the door lifted up to avoid damaging the door  seals.

Primary Air and Glass Pane Air-Flow Cleaning System. Adjustment
The provision of air for the combustion process is performed by means of the Primary Air and Glass Pane Air-Flow Valves.
To favour lighting-up the fireplace and to avoid the formation of tar, we recommend opening the primary air valve completely to allow the inflow of abundant air.
This situation must be maintained at the beginning of each lighting-up process in order to heat the fireplace and chimney, preventing the formation of condensation and tar (Creosote).
Once the chimney has heated up and is drawing correctly, adjust the air flow for the glass pane cleaning system and close the primary Air intake to favour combustion and to keep the glass pane clean.

Cleaning glass elements
At the end of every lighting cycle, and according to the quality of the firewood being used and the draftof the flue, it could be necessary to clean theunburned dust present on the glass. Never cleanthe glass during fireplace operation, always waituntil it has  completely cooled. To open the doorhorizontally, pull up the horizontal opening handle.
Carry out the glass cleaning process using a suitable detergent.

Cleaning of painted surfaces
Never clean the fireplace during fireplaceoperation, always wait until it has completelycooled. To clean painted surfaces use only a smooth cloth slightly dampened with water.

Cleaning the ash pan
The ash pan tray is located under the grill inside thecombustion chamber. Before removing the ash panmake sure that the fireplace has completely cooled.
Never remove the ash pan when the fireplace is lit.
To remove the ash pan lift the grid at the centre of the combustion chamber with the provided tool.
Residues of the combustion can remain very hot also for a long time after the last use of the fireplace, therefore empty these residues only in a metal container.

POSSIBLE CAUSES OF INCORRECT OPERATION

Fume escape:

• The valve in the flue is open, as well as the cover
• Incorrect operation of the flue! • Check the diameter of the flue.
• Height of the flue.
• Check the insulation of the flue
• Check that fumes in the coupling or in the flue can flow without obstacles, otherwise clean.
• Check low pressure in the house (cellar, ventilation equipment, aspiration hood in the kitchen).
• Wet firewood (no heating).

The glass gets dirty:

• Is the firewood dry? (max 20% water content)

Fume pipes gets dirt:

• Poor combustion (cold)
• Is the firewood dry?
• Is the compact fireplace providing its maximum thermal performance?

TROUBLESHOOTING

What to do if… ?

1. Soot covers the ceramic glass too
quickly| Not enough draft
Wrong adjustment
Excessive quantity of Wet firewood
Inappropriate fuel| General observations:
From time to time (according to the frequency of use) it is necessary to clean the ceramic glass with a specific detergent for fireplaces
Refer to the chimneysweep service (it may be necessary to extend the flue or modify the lining of the chimney)
Adjust air intakes as indicated in these instructions (if secondary air inlet is  closed, soot accumulates faster on the glass, while with a correct adjustment it  could clean by  itself)
Refer to the “fuel maximum quality” section
Refer to the “clean combustion” section; you can also use compressed wood logs (they are  usually uniformly dry)
Or: with the use of lignite blocks the glass gets dirty faster than with firewood
2. The fireplace does not feature aregular draft| Not enough draft in the fireplace
The stove is full of soot inside| Refer to the “Short information on materials and ways of combustion” section.
Refer to the “Maintenance and cleaning” section
3. Combustion in the fireplace is not
correct| Atmospheric conditions influx
Incorrect lighting| Refer to the “Fire lighting” section
Refer to the “Fire lighting” section
4. The fireplace releases strong smellsor fumes| Heating phase| Refer  to the   “Openings   for convection air” section
5. Release of fumes when adding fueland during heating| Not enough draft of the fireplace, the  connection of the tube for the outlet of  fumes is not sealed| Check the connection points

If these indications are not enough to solve the problems, contact your authorized reseller or chimneysweep service.
