S4 Electronic Controlled Stoves for Software S4 002 and Higher Thank you for buying a wodtke pellet stove. Please read this manual before installing and putting your stove into operation! This will help you to avoid damage that can occur from improper...
The pellet stove’s intended use is described below. Any other use will be deemed improper. wodtke will assume no liability for any damage resulting from such improper use. Operating the pellet according to its intended use also means complying with the operating and assembly instructions.
Page 5 / 83 2 System Requirements Appliances from wodtke are always connected in some way to other domestic installations or products and therefore, like all technical products, they have certain system requirements that must be met to ensure trouble-free operation. The following sections specify some of most important requirements, which is to say that they do not necessarily name all requirements.
2.2 Minimum room sizes For all wodtke pellet stoves, the room of installation should at minimum have a floor area of 10 m² and a room volume of 15 m³. With Waterplus appliances one must also take into account that the room of installation is additionally heated through heat radiation and convection.
2.5 Room and ambient temperature and humidity during operation All wodtke appliances are designed only for operation in rooms at normal humidity and at room temperatures between +5 °C and +25 °C (ambient temperature during operation). At higher temperatures it can happen that safety devices intervene in the stove’s operation, while...
2.7 Combustion air supply wodtke stoves use room air for combustion, and a sufficient supply of combustion air is therefore essential. The air pressure in the room of installation must not be negative. Please observe the relevant technical rules / regulations and any additional information provided by wodtke when operating your appliance in combination with air conditioning systems (for ex.
Page 10 / 83 4 Functional Description A wodtke pellet stove is a special heating device designed exclusively for wood pellet combustion. During operation the appliance generates warm air which is released into the room. Appliances additionally equipped with an integrated water heat exchanger (Waterplus appliances) additionally produce hot water that is fed into a buffer storage or the domestic heating system.

The combined operation of a wodtke appliance with air conditioning devices such as an exhauster hood, ventilation system or a pneumatic system for wood pellets is therefore only permissible if certain requirements are met.
The entire system must be properly deaerated. The heating system must be capable of delivering heat (radiators turned on, storage cold). *If you are not using a wodtke stove connecting station, the return temperature must instead be raised to >50 °C (ideally 55 °C) and a pump control facility must be installed.
• Open the firedoor. Check whether the burner pot and firebox are free of soiling and pellets and clean burner pot of pellets/ash/slag as necessary. • Put wodtke igniters and a few pellets (never more than a handful) in the burner pot and light them. Tip: Open the wodtke igniter a little before lighting it.
Page 17 / 83 5.6 Appliance types and programmes wodtke stoves have different software programmes installed depending on the model. The programme number appears for a few seconds on the display after switching on the appliance via the I/O key. The present operating manual only applies with the initially installed software (you can check this from menu level 1 –...
This feature can be used to forward messages from the wodtke appliance to an external controller or a modem, permitting remote sampling of functional values, for example. In this case operating states and collective errors are defined as follows.
Burn-back protection is provided by a number of mechanisms, some of which are protected by registered design or patent rights. All wodtke appliances are equipped with a unique fivefold protection against burn-back into the fuel hopper, consisting of pellet chute cooling, wodtke air flow sensor technology, temperature cutoff (STB) and a temperature sensor in the chute.
Page 35 / 83 Note: As a consequence of wodtke air flow sensor technology the appearance of the flames may change with changing draught conditions in the chimney and air temperature because the speed of the fan varies in response to these parameters. This is perfectly normal and in no way a shortcoming.
8.3 Cleaning the viewing window If a deposit forms on the viewing this is normal and in no was a shortcoming. You can easily clean the viewing window with a dry cloth. Heavy soiling can be removed with wodtke special glass cleaner.
The required servicing frequency in turn depends on pellet quality and on whether the appliance is regularly cleaned by the user. Every wodtke appliance is delivered with a special brush for servicing. Soot is an excellent insulator, and appliances that are not serviced therefore tend to deliver less and less heat to the surroundings or to the heat exchanger, thus loosing thermal efficiency.
(measure B). 10.5 Distances from the flue gas connector wodtke appliances are equipped with safety devices that limit the flue gas temperature to 200 °C by automatically reducing fuel feed rate when this limit is reached. For building components requiring heat protection a minimum distance from the hot flue gas connector of 10 cm (measure D) is therefore quite sufficient.
Only pellets approved according to DIN-PLUS, DIN 51731 or Austrian standards may be used in wodtke pellet stoves. It is not permissible to use wood pellets with an ash content > 0,5%, since this would entail an unreasonable amount of cleaning and maintenance.
