### Scope The manufacturer orders the evaluation of ineasurements on flue gas emissions and efficiency. Basis for the evaluation are the results documented in the test report no. H-C3 1190-01 /08 dated 2008-03-15.

Basis of test DIN EN 303-5:1999-06 Heating boilers for solid fuels, hand and automatically stocked, nominal heat output of up to 300 kW, clause 4.2

3 Test documentation Test report no. H-C3 1190-01/08 dated 2008-03-15 on the test of performance requirements of the heating boiler type BioWIN 260

Description The boiler was type-tested according to the requirements of DIN EN 303-5:1999-06 by the test Iaboratory for firing and heating technology of TUV SUD Industrie Service GmbH. A detailed description of the boiler and the test for boiler perFormance are documented in test report no. H-C3 1190-01/08. In the type test a measurement was included for CO, unburnt hydrocarbons, dust emission and efficiency.Page 3 of 4

5 Measurement and analysis methods 5.1 CO2 / CO measurement For the CO 2 / CO measurement a calibrated device on the principle infrared absorption was used. The values are measured continuously during the complete test period. The mean values for CO 2 / CO are 14.6 % / 68 ppm (maximum load) 10.6 % / 151 ppm (minimum load) 5.2 Unburnt Hydrocarbons For the measurement of unburnt hydrocarbons a calibrated device on the principle of flame ionisation detection (FID) was used. The calibration was performed on the basis of propane (C 3 H8). The values for unburnt hydrocarbons are measured continuously during the complete test period. The mean values for unburnt hydrocarbons are 2 ppm (maximum load) 1 ppm (minimum load) 5.3 Particulate emission (dust) For the measurement of the particulate emission (dust) a calibrated filter instrument and a calibrated balance were used in a gravimetric procedure according to CEN/TS 15883, annex A. The dust emission was measured 4 times in the test period. Each period of measurement takes 30 minutes with a constant volume of the sample. The mean values for dust emission are 15 mg/m 3 (maximum load, related to standard reference conditions) 27 mg/m' (minimum load, related to standard reference conditions) 5.4 Efficiency The test was performed by TOV SOD Industrie Service GmbH using a test rig according to picture A.2 of EN 304:2004-01. The values are measured continuously during the complete test period. The mean values for direct efficiency are 92.9 % (maximum load) 92.9 % (minimum Ioad)Page 4 of 4

### Summary The emissions and efficiency as documented in report no. H-C3 1190-01/08 are measured

in line with EN 303-5 regarding the determination of inorganic and organic gaseous or particulate air constituents, using existing procedures in the quality system of the laboratory for firing and heating technology and using calibrated measurement devices.

The calculation of the measured emissions data with reference to 10 % O Z and on the measured data on efficiency as required by EN 303-5 is documented in the test report no. H-C3 1190-01/08.
