  • Page 22: Technical Description Of Attack Dpx Combi Pellet

    6.1 TECHNICAL DESCRIPTION OF ATTACK DPX COMBI PELLET 6.1.1 OPERATING PRESCRIPTIONS Boiler preparation for operation Before starting the boiler, it is necessary to check that the system is filled with water, deaerated and the pressure of heating water does not decrease. Make sure that the sensors of the boiler, safety thermostat and manometer are placed in casings on the upper rear side of the boiler.
  • Page 23 ATTENTION: The pull rod of the heat up flap has to be pushed backwards to close the heat up flap. Otherwise the fan could get damaged! For wood gasification in the boiler it is necessary to keep the reduction layer during the opera- tion (the layer of wood coal on the nozzle in the feeding chamber).

  • Page 25: Operation Of Boiler Attack Dpx Combi Pellet - Wood Mode

    The boiler temperature is at the level set by the enduser, to control the flue gas fan rotations. ATTACK boiler regulator measures the temperature of the water in the boiler all the time and the value shows on the display with improved controller for flue gas temperature by PID. Based on this value, the controller controls the fan rotations and pump of central heating.

  • Page 76: Installation And Chimney Parameters

    1. INSTALLATION AND CHIMNEY PARAMETERS By installation of chimney connection to boiler it is necessary to care about correct outlet of flue gas and eventual condensate, not to let it fall back into the boiler. For this purpose you can use the T-piece, see picture below.

  • Page 77: Verification Of The Correct Chimney Parameters

    2. VERIFICATION OF THE CORRECT CHIMNEY PARAMETERS Correct boiler function significantly depends on quality chimney with correct parameters. Minimum chimney diameter is 150 mm, however, 200 mm is recommended. Chimney has to be designed or regulated to achieve prescribed draught of 23–30 Pa at nominal boiler flue gas temperature value.

  • Page 78: Devices For Chimney Draught Measuring

    3. DEVICES FOR CHIMNEY DRAUGHT MEASURING It is possible to check correct chimney draught by some types of analysers or by exact differential pressure-gauge. On the picture there is draught reducer too, also useful for correct draught setting.

  • Page 79: Operation Pressure In Hydraulic Circuit

    For correct boiler function and its long life-time it is necessary to keep return water temperature always higher than 65 °C. Set boiler thermostat to 80-85 °C, which is ideal boiler operation temperature. Boiler guarantee is valid only in case that the ATTACK-OVENTROP device was installed into the hydraulic system.

  • Page 80: Correct Ashtrays Position

    6. CORRECT ASHTRAYS POSITION Ashtray position is important for correct boiler operation. It is not necessary to take out the ashtray while cleaning, but it is important to check its correct position sometimes. Ashtray has to be completely shifted rearwards. 7.

  • Page 81: Aftercooling Circuit Installation

    8. AFTERCOOLING CIRCUIT INSTALLATION Boiler warranty is valid only in case, that functional thermostatic valve, connected to the cold water source, is installed in the boiler aftercooling circuit. If the cold water source depends on electricity (home water plant), whole device can be out of order in case of power failure. In this cases, use water tanks placed higher than boiler, connected to thermostatic valve.

  • Page 82: Ashtray Cleaning

    10. ASHTRAY CLEANING Internal space of ashtray has to be cleaned from accumulated ash at least 1× a day. Cleaning with scoop is very effective and easy. Cleaning can be done very easily and fast also by full boiler operation. ATTENTION! Hot ash from ashtray can still smoulder, therefore it is not supposed to be put into trash bin, however into appropriate tin-plate bin, not to cause the fire.

  • Page 84: How To Clean Space Around The Ashtray

    11. HOW TO CLEAN SPACE AROUND THE ASHTRAY Space around the ashtray has to be cleaned regularly, at least 1× a week. Use suitable tool, fire hook delivered with boiler is ideal for this purpose. It is not necessary to take out the refractory pieces from the boiler´s ashtray.

  • Page 85: Exchanger Pipes Cleaning By Lever Of Turbulators

    12. EXCHANGER PIPES CLEANING BY LEVER OF TURBULATORS It is necessary to move lever of turbulators cleaning regularly, preferably by every boiler loading, at least 3 times a day. It is necessary to move it by full lever uplift, 5–6 times upwards and downwards.

  • Page 86: How To Clean Space Under Exchanger

    13. HOW TO CLEAN SPACE UNDER EXCHANGER It is necessary to clean space under exchanger pipes in regular intervals. This interval depends on boiler operation time, but it has to be done at least 1× a week. Remove cover of the opening for cleaning carefully, not to damage the sealing.

  • Page 87: Position Of Lever Of Turbulators By Cleaning

    14. POSITION OF LEVER OF TURBULATORS BY CLEANING To clean space under exchanger of the DPX 15, 25, 35 boilers, it is necessary to lift lever of turbulators fully up, turbulators go into the pipes and thereby there is free space for cleaning. By the DPX 45 boiler it is ideal to lift the lever into middle position.
