Further Information
- The heat recovery and efficiency values are those for rated output in standard atmospheric conditions
- The operating sound levels are maximum values measured in 4 directions at a point 1m from the side of the unit and 1.2m above the ground in an anechoic room simulation. The sound levels during actual operation are usually higher than the simulated values due to ambient noise and echoes.
- The values for the external dimensions do not include piping,piping connections, or protuding parts.
- The amount of fuel consumption is based on lower calorific values.
- As for G83, the examination was carried out by New and Renewable Energy Centre (NaREC) in the UK.
