*
when working with medium load (50% of rated power) for the fuel dedicated referred to in chapter 6. In the actual conditions the fuel consumption
may differ from the one given in the table. The fuel consumption is impacted the quality of the fuel, type of heating installation, operating
parameters of the boiler, chimney, degree exchanger contamination, inside and outside temperature of the heated building, building insulation.
**
when recommendations concerning maintaining of a specified range of heating water temperatures are not followed, the boiler must be obligatorily
connected to the heating system equipped with a four-way valve protecting against so-called „low-temperature corrosion”
***
temporary power consumption depends on the equipment operating mode
**)
when adjustment feet are used (excluding boilers of the power exceeding 25 kW), the dimension increases from min. 29 mm to max. 56 mm
