1. Boiler’s use Wood is the main fuel for the Eko-Vimar Orlański Sp. z o.o. boilers. Wood at 15-25 % humidity and length about 5 cm smaller than the loading chamber should be used as the main fuel (billet’s diameter - 15-25 cm - check „technical data”). OTICE! N Using different than ordinary fuel doesn’t guarantee boiler’s right operating - as it was featured in technical data and it can influence the boiler’s way of working and its long-lasting.
2. Procedure rule Wood gasification boilers work in pirolitic wood distillation process. When the air is limited wood changes into charcoal while burning up. In the same time wood gas appears, which next relocates to burner’s nozzle and there it is burnt at the bottom of the boiler. Such method of wood burning allows for its effective using as fuel.
Chimney sweep should approve smoke outlet before its connecting to a chimney flue. According to the PN-EN 303-5 norm accumulation tank should be assembled together with wood boiler. We choose about 55 l heating water for every 1 kW installed power for example Orlan 25 kW = 25 kW x 55l = 1375 l 3.1.

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. 4.3.
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 (65 °C), after room thermostat’s connecting we change regulation for below 65 °C (in the type 3.4: +65 °C up to +90 °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.
Pic.4 Regulator operation and wiring system scheme. OTICE! N Pump live wires’ connections and fuse’s replacement should be made when the regulator is OFF ( connecting plug should be taken out of the current slot). If the condition is not made it may cause electric shock.

6. Connecting and exploitation 6.1. Connecting 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.
6.2. Wood and gasification It is important that wood gasification boilers worked in specific conditions. Boiler’s temperature accounts for above 75 °C. At lower temperatures gasification doesn’t procees in a correct way and what follows - wood intake is relatively higher. Wood drying in a loading chamber is an essential stage in gasification process - wood doesn’t have adequate temperature at lower temperatures and all of the process is inadequate.
Optimum humidity Outside drying - in months Pic.7 Hygrometer - an appliance for humidity measurement - in Eko-Vimar Orlański’s offer. Wood humidity [%] Tree’s chopping off Pic.8 Wood humidity chart. 6.3. Accumulation The best results in heating gives boiler’s connecting with an accumulation tank. Such installation causes less wood using - even up to 40 %.
6.4. Starting Before first boiler’s use there should be checked: leakproof of the threaded joints (whether there isn’t any leak) installation water level, the parameters of boiler’s operating are to be set as well. 6.5. Burning up The steps to be taken to burn up in the boiler: 1. Switch off the power. 2. Push the chimney flap (gas pass opened). 3. Place splinters and some bigger wood pieces to the boiler upper chamber. 4. Burn the paper and close the upper door. 5.
NOTICE! Lack of fuel is signalled with a red indicator . 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. Optimum 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 75 °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 described 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.
The Eko-Vimar Orlański advices using SADPAL - a catalyst for wood tar burning. It is to burn up the wood tar all over the boiler, beginning with a burner, combustion chamber and a chimney. All details according the SADPAL use are written on a packaging. The product is available in Eko-Vimar Orlański offer. 7.4. Leakproof securing Leakproof of the boiler is very important especially leakproof of the door, the exchanger and chimney flap.
