Wood burning cast iron stove KRATKI K6 Ø 130 8 kW

Cast iron wood-burning stove K6 – heats from 50 m² to 110 m²

The K6 cast-iron stove combines functionality, safety and aesthetics, making it an ideal solution for interiors that require both efficient heating and a stylish appearance.

The firebox walls, made of solid cast iron with a thickness of 8 mm, ensure long durability and resistance to high temperatures. The decorative guard not only enhances the aesthetic value of the stove but also provides additional safety by preventing logs from accidentally falling out.

The K6 stove meets the Ecodesign criteria.

TECHNICAL DRAWING ✍️

❎ FLUE OUTLET Can be installed in various mounting conditions thanks to the adjustable flue outlet: at the back or on the top of the stove.

❎ REMOVABLE ASH PAN A drawer/container for ash where the residue from burned wood accumulates. It can be removed and cleaned easily.

It also facilitates manual control of the combustion process via the ash pan.

❎ REMOVABLE GRATE The stove features a sturdy cast-iron grate. It can be removed and cleaned.

❎ SAFE GLASS AND COOL HANDLE Reduced soot build-up thanks to the clean-glass system (air curtain). The classic insert front is equipped with heat-resistant ceramic glass that withstands temperatures up to 660°C.

The cool-handle system allows you to remove it while the stove is burning. This way it does not heat up and you can easily add wood.

❎ BUILT-IN DEFLECTOR Afterburning of fuel particles thanks to the deflector, which lengthens the path of the flue gases. This process also increases combustion efficiency and ensures better energy use, while minimizing the emission of harmful substances into the atmosphere.

❎ CAST-IRON LEGS

☘️Recommended Fuel:☘️ ☑️Types of wood: Beech, hornbeam, oak, alder, birch, ash.

☑️Dimensions: Length approx. 30 cm, circumference 30 cm to 50 cm.

☑️Wood moisture: Should not exceed 20%, corresponding to wood seasoned for 2 years and stored under a roof.

⚡️Not Recommended Fuel:⚡️

☑️Avoid wood with moisture above 20% – it may reduce heat output.

☑️Do not use logs from coniferous and resinous trees, which can heavily soot the appliance and require more frequent cleaning.

☝️Prohibited Fuel:☝️

☑️Do not burn: coal, tropical wood (e.g., mahogany), chemical products, liquids (oil, alcohol, gasoline, naphthalene), or materials impregnated or pressed with glue, such as laminated boards or waste.

☑️Important: If other fuel is permissible, you will find this information on the appliance’s nameplate.

REMEMBER!

Our fireplace insert comes with a manual containing all information regarding operation and installation.

⚡️Freestanding Stove Lighting Instructions step by step:⚡️ ⭐️Preparing Materials⭐️

✅Use several larger logs (max. moisture 20%; diameter approx. 10–13 cm).

✅A handful of kindling sticks (max. moisture 20%; diameter approx. 2–5 cm).

✅Firelighter – matches/lighter.

⭐️Preparing the Firebox⭐️

✅Open all air inlets and dampers.

✅Lay larger logs alternately on the bottom of the firebox.

✅Place a layer of kindling on top (no more than 3 layers).

✅Leave gaps between sticks for better airflow.

✅Place the firelighter on the top layer.

⭐️Ignition⭐️

✅Light the firelighter and close the fireplace door.

✅In case of weak chimney draft, slightly open the fireplace door or a window in the room at the beginning of lighting.

⭐️Important Tips⭐️

✅Fuel: Use wood with moisture content up to 20%. Avoid burning coal, coke and other prohibited materials.

✅Wood moisture: Wood should be seasoned for 18–24 months or kiln-dried. Using wood that is too wet may lead to increased energy use and creosote formation, which compromises safety.

✅Recommended wood: Oak, beech, hornbeam, birch. Coniferous trees can heavily soot the glass and have lower energy values.

Following these rules not only ensures efficient and safe use of the stove but also financial savings and better heating quality.
