10 2 Safety notes – Intended use Wood moisture comparison Proper use includes maintaining the installation, operation and maintenance conditions specified by the manufacturer. You may only enter or change the operating values specified in this guide. Any other entries will affect the heating system's control program and could lead to a malfunction. Permissible fuels The operator of a wood heating system, you can considerably influence its efficiency and emissions. A minimum of emissions can be achieved by burning well-dried, split wood. Waste wood or dirty, decayed and very wet wood requires energy for drying, produces less heat and reduces the service life of the boiler. You can only achieve maximum heating performance of the boiler (nominal output) and minimum emissions by using dry wood. The huge influence of water content upon the thermal value is made clear by the following table. All wood should be split and ideally no more than 20% moisture. Water content (wet basis) 15% 20% 25% Wood moisture (dry basis) 18% 25% 33% Conversion factors Table 2/2 - Wood moisture comparison 1 kg wood (dry) approx 4 kWh 1 l oil approx 10 kWh 1 l oil approx 2,5 kg wood 1.000 l oil approx 5 - 6 rm hard wood, stacked log wood 1.000 l oil approx 7 - 8 rm soft wood, stacked log wood 1.000 l oil approx 10- 15 srm piled wood chips Explanation Table 2/3 - Conversion factors 1 srm = 1 m 3 piled wood chips (loose) 1 rm = 1 m 3 stacked split wood (stere) 1 fm = 1 m 3 solid wood (without gaps) Table 2/4 - Explanation HDG Navora 20/25/30 with HDG Lambda Control 1 - V 2 - en © HDG Bavaria GmbH 06/2008
2.2 Residual risk 2 Safety notes – Residual risk Despite all precautions, the following residual risks remain: Caution! Hot surface. Contact with the hot surface of the boiler can lead to burns. Wait until the boiler has cooled down before touching uninsulated components. Warning! Danger of asphyxiation due to carbon monoxide. If the boiler is operating, carbon monoxide can be emitted through the open ash or fuel loading door. Do not leave the ash or fuel loading door open any longer than necessary. Caution! Danger of fire Working in areas marked with this symbol can lead to a fire. Do not leave the combustion chamber and/or fuelling chamber door open any longer than necessary. 2.3 Warnings and safety symbols used The following warnings and safety symbols are used in this Planning and installation guide: Danger! Danger from electrical current or voltage. Work on areas marked with this symbol may only be done by a qualified electrician. Danger! Dust explosion due to build up of static charge. Work on areas marked with this symbol can lead to serious injuries or to extensive material damage. © HDG Bavaria GmbH 06/2008 HDG Navora 20/25/30 with HDG Lambda Control 1 - V 2 - en 11
