Pressurisation values should be included in the range given in the table of technical specifications. WARNING The differential temperature between boiler flow and return must not exceed 15°C in order to prevent thermal shock to the boiler structures. The temperature of the return water must be above 55°C in order to protect the boiler from corrosion due to condensation of the flue gases on cold surfaces;... - Page 27 Iscritto R.I.
