DEAR CUSTOMERS! Thank you for placing your trust in us and purchasing our stove used for local heating. We assure you that you have chosen a cost-effective, quality product, which is the result of our extensive experience in manufacturing stoves and furnaces that are used for local heating. We hope that we fully met your demands in both design and the size of the living area you need to heat.
If a cabinet is mounted above the stove, minimum clearance between the stove’s cooktop and the cabinet should be at least 70 cm. Combustible materials (e.g. wallpapers, door casings, doors, etc.) require a clearance to flue pipes of at least 20 cm. This clearance can be reduced if flue pipes are thermally insulated and if the temperature of surrounding objects does not exceed 80°C.

A chimney is properly functioning, if it meets the following conditions (Fig. 3): If it extends the height of the rooftop (ridge, highest point) by at least 0.5 m, If it extends the height of the house adjacent to the chimney, tree or other barrier, If it is built inside house walls or, if the chimney is built on the outside walls, it must be well insulated, If the chimney connection is tightly connected to the chimney, if the connection is extended, If it is properly cleaned and free of birds nests, dirt and soot,...
6. INSTALLING THE STOVE IN THE WATER HEATING SYSTEM The stove should be installed by a professional, in accordance with appropriate design. The stove is intended for local and central heating. The stove can be installed in closed or open heating circuit. Conform to the standards: JUS M.E7.201 and JUS M.E7.202.
6.2 THERMO VALVE (Fig. 7, Item 13) Installation of a thermo valve is MANDATORY in a closed circuit. This specially refers to a closed circuit, when the radiators are submerged and where, in the event that pump operation is stopped for any reason, water temperature in the boiler rapidly increases and overheating occurs very quickly.
7. PRACTICAL INSTRUCTIONS AND HEATING SYSTEM OPERATION ADVICE - We recommend you to use a closed circuit, due to corrosion hazard related to open circuits. - All connections must be well sealed and tightened. - Before startup, the entire system needs to be tested with water under 2.4 bar pressure. - It is recommended to discharge the water from the system at least once, to empty the system of dirt.

- It is preferable to install an R1" multistage pump with a flow rate capacity that always meets current system needs. Install block valves immediately downstream and upstream of the pump to enable removal of pump for repairs, replacement etc. without discharging the water from the system. - Install the spigot used for filling and discharging the system on the return pump at the lowest point of the system.
The firebox can also be filled from the cooktop (Fig 12). Lift the cooktop lid using a wrench and load the fuel. It is not recommended to burn organic or other waste in the stove (plastic bags, bones, etc.) because this causes formation of tar deposits on the flue duct walls, which can cause a fire.
11. SECONDARY AND TERTIARY AIR REGULATORS Secondary air regulator is placed in the firebox door (Fig. 1, Item 8 and Fig. 13). It controls additional lighting of fire and burning unburned flue gases. It is opened and closed manually using the knob on the firebox door. Leave the secondary air regulator open when the fire in the stove is lit.
14. CLEANING AND MAINTENANCE Each time before loading the fuel, clean the grate using a small shovel by opening the grate holder or through open firebox door. Remove the ashes from the ash pan at least once a day and remove the larger residues by opening the ash pan door and grate holder.
