Main pipe for the fuse cable Abbildung 12: Pellet boiler Abbildung 13: Overview of the PL15 mechanism If the boiler has been fully connected to the heating system with both water and electricity supplies, the PL can be operated. At first, the pellet bin must be filled up. The filling is done by hand. We recommend that the bin should always be filled up to the top to ensure a good, long operation. The filling up of the pellet storage bin can also be done automatically with the aid of an optional external feeding facility. Further information about his can be found in our material. Important: The KUENZEL pellet boiler is equipped with an automatic fire pan ash–emptier. The ash– emptying cycle is introduced after each burn–out. If there’s no burn–out for a certain amount of time, the 14
control panel will induce a burn–out and, in turn, an ash–emptying cycle will start. Further details about this can be found in the control panel instructions manual. When the pellet storage bin has been filled with fuel, the boiler can be operated. There are two different basic modes of operation: 1.17.1 Operation without Heating Electronics In the standard version, the PL is operated without weather–responsive heating electronics. In order to set the boiler in operation, the control panel is switched on at the ON/OFF switch. Then the boiler begins with the ignition. The remaining minutes of the ignition period appears in the left–hand segment of the display. The ignition process finishes either at the end of the ignition period or when the control panel has recognized that the pellets have definitely been ignited due to a sudden rise in the exhaust gas temperature. The PL should now run at full load operation until the boiler reaches a temperature 10 K (you can choose a value between 30 K and 10 K) below the pre–set boiler target temperature. If this happens, the PL will switch itself automatically to partial load operation. If the boiler temperature decreases under the threshold value again, the PL will switch itself back onto full power. Should the boiler exceed the pre–set boiler target temperature, despite the boiler being in partial load operation, the burner switches itself off. In the left segment of the display, the letter „A“appears. If the exhaust gas temperature falls under 90◦ C, the letter „E“appears in the display. The pellet boiler now goes through an automatic fire pan ash–emptying cycle. As soon as the temperature sinks under the adjustable switch-on temperature (pre–set by factory onto 70o C) again, the burner starts automatically and the work cycle begins again. If the PL shall be stopped, the START button must be pressed again until the letter „A“appears in the left segment of the display. The boiler target temperature can be set between 80o C and 87oC. The long hysteresis between the points of turning on and off ensures that the burner runs for a long time. This ensures that the operation runs more economically and with low emissions. 1.17.2 Operation with Heating Electronics A PL can be optionally equipped with weather–regulated heating electronics from KUENZEL. It should also be noted that the connection box of the type no. 150252 is compulsory for the operation with weather–influenced heating electronics. Caution: A cable must be fitted by client from the connection box to the burner point of contact on the 806–control panel. The clamps 1 and 2 of the connection box should be connected to the clamps 3 and 4 of the bottom sensor plugs on the 806. In order to ensure that operation runs in the best possible way, the steepness of heating characteristics of the boiler circulation should be set to 2.5, the burner–switch difference to 10 K, the minimum running time of the burner to 10 minutes and the boiler maximum temperature to 85o C. The boiler and the tank start relief are switched on. These jobs are only allowed to be carried out by a heating technician. To reassure that the Control Panel 806 recognises the heating electronics correctly, move the DIP–switch on the back of the control panel into the position „heating electronics“˙To do this, read also the appropriate chapter in the control panel manual. In order to set the boiler in operation, the control panel should be switched on using the ON/OFF switch. Then the START–button should be pressed. If now the heating electronics request heat from the burner, 15
