    - It is obligatory and essential to install the temperature relief valve supplied with the boiler. To correctly install the boiler, carefully follow the instructions given in the section "Installing the temperature relief valve" . If this requirement is not complied with, DOMUSA TEKNIK's guarantee of the appliance will automatically be null and void.

  • Page 7: Fuel: Preparing The Firewood

    Firewood is the fuel which must be used for the Lignum NG boiler. If this requirement is not complied with, DOMUSA TEKNIK's guarantee of the appliance will automatically be null and void. The quality of the fuel plays an important part in the performance and useful life of the boiler. The firewood must have less than 20% water content (humidity).
  • Page 8 Lignum NG Make sure the logs in the fuel loading compartment do not get stuck (avoid logs which are too long). If the logs are too long, they do not fall properly and can cause gaps, causing a drop in the boiler power.

  • Page 9: Ignition And Positioning Of The Firewood

    3.4 Ignition and positioning of the firewood How the firewood is loaded into the housing is very important for an optimised combustion process. It is recommended that the firewood be inserted into the loading compartment as follows: Insert thick pieces of wood or stumps in the top area only 4th Layer: Medium firewood - Load the necessary amount in the compartment...

    Otherwise, the condensation may reach the inside of the boiler and cause irreparable damage, which would not be covered by DOMUSA TEKNIK's guarantee. The condensation pipe should lead to a drain outlet, as a large amount of water may be generated.

    Lignum NG IMPORTANT: Before carrying out any work on the boiler's electrical installation, always ensure it is disconnected from the mains. IMPORTANT: Make sure that none of the mains cables come into contact with a hot surface (e.g. flue). 3.8 Example of an installation with a buffer tank The Lignum NG boiler is equipped with an electronic control that can govern a circuit with buffer tank, with an external circulation kit to prevent condensation in the heat exchanger.

  • Page 13: Example Of An Installation With A Buffer Tank And Dhw Tank

    To control a DHW circuit, connect a DHW sensor from the hot water tank to the boiler (optionally "Electrical Diagram supplied by DOMUSA TEKNIK) and a 3-way diverter valve (see ” The figure below shows an example of a hydraulic diagram for a heating installation with radiators...

  • Page 14: Adjusting The Combustion Air

    Lignum NG 4 ADJUSTING THE COMBUSTION AIR The various stages of combustion (drying, pyrolysis, gasification and combustion) of the Lignum NG wood boiler take place in a controlled manner in different parts of the boiler. The wood dries and decomposes in the loading compartment via the technique known as "inverted draught", generating a combustible gas.

  • Page 15: Temperature Relief Safety Valve

    5 TEMPERATURE RELIEF SAFETY VALVE In order to avoid the temperature inside the boiler reaching damaging levels, this valve opens and lets the mains water supply pass into the interior coil, thereby dispelling the heat in a fully reliable manner. This occurs when, for hydraulic reasons or due to lack of electric current, the boiler cannot dispel the heat it is generating.

  • Page 16: Starting Up The Boiler

    6.1 Prior warnings Repair and maintenance of the boiler must be carried out by a qualified professional, authorised by DOMUSA TEKNIK. For optimum functioning and conservation of the boiler, it should be serviced annually. Carefully read this instruction manual and keep it in a safe, easily-accessible place. DOMUSA TEKNIK will not be liable for any damages caused by failure to follow these instructions.

    Lignum NG 8 BOILER MAINTENANCE AND CLEANING 8.1 Cleaning the boiler 8.1.1 Ashes The ashes must be cleaned out regularly and properly after every 3 or 5 loads of firewood, depending on the type of wood. The ashes accumulate in both the loading compartment and the refractory combustion chamber and in the flue.

  • Page 21: Boiler Maintenance

    8.2 Boiler maintenance: Various maintenance operations should be carried out at different intervals to keep the boiler in perfect working order. The most important aspects to be checked are as follows: Operation Frequency Clean ashes from the loading compartment, combustion chamber and 3-5 loads of flue.
