for operation at a moderate load (50% of boiler nominal output) for basic fuel.
**
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 three- or four-way valve protecting
against so-called "low-temperature corrosion"
*** temporary power consumption depends on the equipment operating mode
