  • Page 3: Using The Boiler

    1. Using the Boiler Dry, seasoned wood is the recommended main fuel source for the EKO boiler. Optimum wood moisture should be between 20 and 25 percent. The length of the wood pieces should be about two inches shorter than the depth of the burning chamber. Warning! Using fuel types other than the dry wood specified above may result in unpredictable operation and poor efficiency.

  • Page 4: Installation Guidelines And Clearances

    3. Installation Guidelines and Clearances Orlan EKO boilers are designed to conform to, and be installed in accordance with, the stringent European regulations known as PN 87/B 02411 and PN-91/B-02413. When installed in the United States, all applicable local codes and regulations should be observed.

    4.3. Connecting a pump and room thermostat to the controller There are several electrical terminals on the back side of the RK 2001 controller where a pump and room thermostat can be connected. Access is through the bottom of the controller housing, which is attached to the top front boiler panel with four screws.

    6. Connecting and Operating the EKO Boiler 6.1. Installation guidelines A four-way mixing valve is an essential component of any EKO boiler installation. When properly installed, it allows hot supply water to be automatically mixed with cooler return water to avoid low return water corrosion at the boiler return water connection and maintain a relatively stable boiler water temperature.

  • Page 10: Wood Fuel Considerations

    6.3. Wood fuel considerations As noted earlier in this manual, the moisture content of the wood used to fuel the boiler should be between 20 and 25%. Hardwoods such as beech, oak, maple, hickory, etc. are best. While it is possible to burn dry softwood such as pine, spruce, fir, hemlock, etc,. they will burn faster and require more frequent loading of the boiler than with hardwood.

  • Page 11: Hot Water Storage

    6.4. Hot water storage For the best results, the use of a heat storage tank is recommended. A properly sized storage tank can cut wood consumption by as much as 40%. Hot water storage allows the boiler to run at optimum capacity regardless of the demand for heat from the building being heated.

  • Page 12: Fuel Loading

    When starting the boiler, the following steps should be followed in sequence: 1.) Switch off the power. 2.) Push the chimney damper lever in to open the burning chamber bypass. 3.) Put paper, kindling and a few larger pieces of dry wood in the burning chamber. 4.) Start the fire.

  • Page 13: Operating Temperature

    6.8. Operating temperature Maintaining the proper temperature of the water in the boiler during operation is very important. For proper gasification to occur, the boiler water temperature should be 70°C or greater. At times, such as when there is a large call for heat, the return water temperature may become too low.

  • Page 14: Boiler Maintenance

    7. Boiler Maintenance 7.1. Offseason preparation It is important that the boiler be properly prepared for the offseason (summer) idle period. The upper and lower combustion chambers, heat exchanger tubes and chimney bypass damper should all be thoroughly cleaned. After the boiler is cleaned, both doors should be left open to avoid condensation in the boiler.

  • Page 15: Maintaining Tight Seals

    7.4. Maintaining tight seals It is very important to maintain tight seals on the doors, heat exchanger cover plate and the firebox bypass chimney damper. Poor seals can result in smoke and gasses leaking out of the boiler, and lead to uncontrolled burning which may cause the boiler to overheat. The insulation rope used to seal both doors and the heat exchanger cover should be inspected regularly and treated with graphite or some other lubricant as needed, to keep them flexible.

  • Page 16: Cleaning The Eko Super 1 Model

    7.6 Cleaning the EKO Super 1 model The EKO Super 1 model boilers are equipped with a lever-operated heat exchanger cleaning device consisting of spiral steel elements that clean the tubes as the elements are moved up and down. Vigorously moving the handle back and forth either before or after each fuel loading will help assure that the heat exchanger does not become clogged with creosote, carbon or ash.
