Do not drain water from the central heating system during standstill. Unless it is required for repair
or assembly work. In order to prolong the life of the boiler it is recommended to leave the boiler in
an open position for the time of standstill, enabling free air flow through its interior, and
consequently drying.
NOTE!
Due to the specificity of the boiler operation, under normal conditions of its operation in
accordance with the manual and protection in the open system according to PN-91/B-2413,
in case of lack of electricity the boiler is automatically extinguished and does not pose any
danger.
