Frequently Asked Questions
Bad combustion in the chimney stove (insufficient draft) or smoke creation when adding fuel or during operation |
|
| The chimney or smoke-flue is not airtight (false air is sucked up). | Have the chimney checked (seal the chimney door if needed). Put flue tubes together correctly or replace damaged tubes. |
|---|---|
| Bad chimney draft. | Have a chimney sweeper (stove builder) find the cause of problem and take measures, for instance clean the chimney, remove smoke-flue reductions, heighten the chimney, bring enough air to the room. |
| Another heating chamber door connected to the chimney is opened. | Close the door of that heating chamber. |
| Chimney cleaning holes are opened. | Close the cleaning holes. |
| Equipment and smoke-flues are polluted or clogged. | See. Operating Instructions, Chapter 6.1. Cleaning of Heating Appliance |
| Insufficient fresh air input. | See. Operating Instructions, Chapter 4.9. Outer combustion air input |
| Deteriorated outdoor weather conditions. | See. Operating Instructions, Chapter 5.5. Operation during transition periods |
| Wrong fuel was used for the fire. | Use correct type of fuel, see Operating Instructions, Chapter 2.2. Fuel |
The stove fails to heat up quickly |
|
| Wrong fuel load. Not enough fuel for correct ignition. | Add fuel for correct ignition and subsequent combustion, see. Operating Instructions, Chapter 5.2. Ignition and heating |
| Close primary air inlet. | Open the primary air regulator or throttle down the secondary air regulator. |
| Exchanger takes too long to cool the heating chamber. | Install a circulating pump temperature regulator to the exchanger outlet and set the regulator to approximately 55 °C. Stop some appliances (heaters). Add a thermo-regulation valve (e. g. ESB) to the hot water system |
The room is not sufficiently heated |
|
| Too much heat is needed, or the stove has low capacity. | Consult a heating engineering (stove builder). Reduce heat loss in the room (e. g. through thermal insulation). |
| Smoke-flues and stove are polluted. | See Operating Instructions, Chapter 6.1. Cleaning of Heating Appliance |
| Chimney draft is too weak. | See. Operating Instructions, Chapter 4. CHIMNEY STOVE INSTALLATION AND CONNECTION TO CHIMNEY |
| Incorrect operation of the stove | The heating appliance adjustment (heat output) is not optimal, see Operating Instructions, Chapter 2.1. Fuel quantity and combustion regulation |
The chimney stove has excessive heating output |
|
| Incorrect operation of the stove | The heating appliance adjustment (heat output) is not optimal, see Operating Instructions, Chapter 2.1. Fuel quantity and combustion regulation |
| Ashtray door is not completely closely. | Close tight the ashtray door. |
| Door or ashtray sealing is damaged. |
Replace door sealing. |
| Chimney draft is too strong. | See Operating Instructions, Chapter 4. CHIMNEY STOVE INSTALLATION AND CONNECTION TO CHIMNEY |
The stove smells bad and is smoky |
|
| Chimney draft is too weak. | See Operating Instructions, Chapter 4. CHIMNEY STOVE INSTALLATION AND CONNECTION TO CHIMNEY |
| Protective varnish or the stove is soiled or covered with dust. | The paint burning will stop in a short time (smoke and bad smell) or you can clean the stove in a cooled state. |
The looking hole is clogged |
|
| Causes are difficult to determine. Most often, these are: wrong type of fuel, incorrectly adjusted combustion, bad or temporary deteriorated chimney draft, leak of door sealing. | Rule of thumb: Depending on the method of heating and type of fuel, the door needs occasional cleaning, see Operating Instructions, Chapter 5.4. Clean state of glass. When using coal briquets the glass door can clog more easily than when using wood as fuel. |
| Chimney draft is too weak. | See Operating Instructions, Chapter 4. CHIMNEY STOVE INSTALLATION AND CONNECTION TO CHIMNEY |
| The heating chamber is overloaded with fuel. | Use appropriate quantity of fuel, see Operating Instructions, Chapter 2.1. Fuel quantity and combustion regulation 5.3. Adding fuel |
| Wet fuel was used. | Use only dry fuel, see Operating Instructions, Chapter 2.2. Fuel |
The exchanger output is not sufficient |
|
| Heat exchanging surfaces are clogged. | Clean heat exchanging surfaces with supplied brush. |
| The stove is not operated at sufficient output, economy mode is set (throttled air regulators). | Increase the stove output by opening air regulators. |
| The system does not have sufficient water pressure (suffiecient water volume) | Check water pressure (water volume) and pressurize the system (add water). |
The heating system is overheated |
|
| The heating system has insufficient heat output. | Check heating appliances (potentially turned on heaters, …) or pump function. You can also consult an expert. |
Other problems |
|
| What is "tertiary combustion"? | Tertiary combustion means the inlet of very hot pre-heated air to the combustion chamber which improves the process of exhaust products combustion, reduces the content of dangerous substances and increases the stove efficiency |
| What is "external air inlet"? | It means air supply from outdoor space. The combustion does not use oxygen from the room. |
| What is "automatic regulation of secondary combustion"? | This process ensures optimal burning and low emission values. |
| What is "cooling loop"? | This is one of the possible ways of protection against overheating in case of power outage. |
| Can I use a stove with exchanger even if there is no water in the exchanger? | By no means! All stoves with exchanger produced by our company have a removable exchanger. If you wish to use the stove temporarily without connection to the heating system you need to purchase a plug element, remove the exchanger and replace it with a plug. When you need to connect the exchanger, perform the steps in reverse order. |
