The diagrams are purely indicative, therefore they do not have design value.
Installation, relative system connections, commissioning and verification of correct operation must be carried out correctly by professionally
qualified and trained personnel in full compliance with current national, regional, provincial and municipality regulations in the country
where the appliance is installed.
Size the system correctly to avoid long pause times that would cause significant problems like the ones mentioned in the section regarding
DOWN-FIRED BOILER OPERATION.
ATTENTIoN : the boiler's circulator operates based on the differential temperature between the boiler and the puffer. if the
boiler's temperature drops below the temperature of the puffer, the circulator stops.
