In case of long-term idle state of the boiler in winter or if pipe freezing danger appears it is necessary to drain
the water out of the boiler and the heating system.
Do not keep highly flammable and volatile substances (gasoline, solvents etc.) in the premise where the boiler

3) Do not use electric appliances in order to avoid the appearance of spark;
4) Do not use the telephone in a gas-polluted premise
5) Do not smoke and do not use open fire (lighters, matches etc.)
6) Call the gas facility emergency operation service immediately
Usage of the boiler when it is out of order or non-compliance with the above-listed rules of exploitation
may lead to an explosion or fire, or poisoning with gas or combustion products.
