1. Boiler’s use Wood is the main fuel for the Eko-Vimar Orlański boilers. Lignite or minced coil could be an alternative fuel. Wood at 15-20% humidity and length at about 5 cm smaller than the loading chamber should be used as the main fuel (billet’s diameter - 15-25 cm - check „technical data”).
3. Installation Wood boilers are to be installed according to the present norms and rules. The requirements of norm PN 87/B 02411 according building of solid fuel boiler room and the norm PN-91/B-02413 according open system boilers’ producing should be taken into account. Eko-Vimar Orlański company prescribes using chimney inputs which preserve against the chimney permeating. The company doesn’t take responsibility in case of faults resulting from not using chimney inputs. 1.

Regulator’s description Since the 30.06.2006 wood boilers were equipped with RK 2001 regulator. In 01.07.2006 new ones were brought out - EKOSTER 2. Main functions of both regulators are similar, but there is a difference in parameters’ modification ( EKOSTER 2 ). 4.1.
4.2. Regulator system functions (RK 2001) Boiler’s temperature setting at 60 up to 80°C We set the boiler’s temperature with a knob (6). Current temperature is displayed on the screen (2). Boiler’s overheating signalling The indicator (4) tells about boiler’s temperature excees to 90°C. In the case the fan switches off. Lack of fuel signallisationl If in 30 minutes temperature doesn’t reach 60°C, the indicator (8) and the fan will turn on.

N If the “Er” appears on the screen it means that temperature either raised over 99°C, it decreased below -9°C or the sensor got damaged. To secure together the boiler and installation up to the time of the sensor replacing pump should be continuously on till that time. 4.6.
COMFORT SYSTEM facility The COMFORT SYSTEM function built into the regulator prevents against stone deposition between pump rotor and stator. The regulator automatically actuates the pump after the heating season for about 30 seconds, every 14 days. Operation of the pump in this mode is signalled by pulsation of PUMP indicator. The system begins to operate 1 minute after regulator’s switching on. Actuation of the pump in automatic mode causes re-counting of the 14-day period from the beginning.
Settings in correct order: • „HI”: hysteresis of boiler’s temperature regulation (2°C - 9°C), that is temperature’s decreasing to the low enough to cause fan’s turning on. • „Po”: temperature when the pump turns on (35°C - 70°C), after room thermostat’s connecting we change regulation for below 65°C till the time when „rP” appears on a display - Ekoster on basis of the signal transmitted by the room regulator will control with pump’s working on its own.

6. Connecting and exploitation 6.1. Connection Four-way mixing valve is essential for any installation. It’s role is to mix hot water (contribution water) with the one returning from the system. Water mixing is necessary as to avoid „cold return of the water” and to keep the same temperature of the boiler. What follows the temperature of heating system’s feeding can be lowered to the temperature of satisfactionary warmth in the house.
Right quality of wood warranties proper boiler’s working. Using the fuel at different parameters doesn’t guarantee correct boiler’s operating.

6.3. Accumulation The best results in heating gives boiler’s connecting with an accumulation tank. Such installation causes less wood’s using - even up to 40%. Gasification process (if it runs in optimum way) generates large gas quantity, heating system however is characteristic for large fluctuation amplitude in warmth requirement scope. Gasification process is set only in certain way, heating system fluctuaction change more often, room might get overheated or some extra gas can get through the chimney.
(ca. 10 cm) (chopping of the wood in about 5 cm pieces at the first stage of burning up accelerates embers’ producing) 8. Wait for 15÷20 minutes for the ember layer occurring 9. Fill up the whole combustion chamber 10. Close the upper and bottom door hermetically 11. Pull the chimney flap and switch on the fan ARNING! W It is forbidden to switch on the fan when the upper door is opened.
6.7. Boiler’s putting out Boiler puts out in two ways: after turning off button pressing or after all of the wood burning out. 6.8. Right boiler’s temperature assuring Right boiler’s temperature maintaining during its exploitation is very important. To assure correct gasification process water temperature should be about 70°C. In the time of a large warmth need returning water’s temperature may lower.
7. Conservation 7.1. Boiler’s conservation Except for the elements descried in „BOILER’S EXPLOITATION” preserving it is important that the boiler was protected during its stagnation (summer time, householders’ absence). Boiler’s interior, hest, exchanger, chimney flap should be cleaned through - it’s advisable to burn some dry softwood (ex. spruce) in the boiler before its stopping over - it will burn out the waste occuring during boiler’s exploitation.
7.4. Leakproof securing Leakproof of the boiler is very important especially leakproof of the door, the exchanger and chimney flap. Leakproof causes the fumes’ coming out of the boiler and most of all it can cause uncontrolled burning which may cause boiler’s overheating. To ensure the exchanger’s door leakproof the insulation rope should be sealed with a graphite oil or some other machine oil at least once a week. It soften the rope and causes its tight adjoining to the boiler.

10. Utilizing The appliance is approved according to the European Directive 2002/96/EC in the matter of electrical and electronic devices’ waste (WEEE). Ensuring right its scrapping you help to protect the environment. Wrong utilization of the appliance may cause negative influence on the environment. To prevent it - make sure that you utilize the boiler in a proper way. The symbol placed either on the device or in the documents enclosed means that the product isn’t classified as a household waste.
