Devices under pressure
1. Avoid contact with the parts of heating system under pressure during operation of boiler. These dangerous parts
are such that:
Boiler sections
Boiler inlet and outlet lines
Safety lines
Pressure relief devices installed on heating system
2. Never attempt to drain water from heating system when the boiler is being operated
3. Never feed the boiler directly with cold water to cool it down for any reason, when the boiler is hot.
High temperature surfaces
Avoid contact with parts and surfaces having high temparutares which will be hazardous for human such as:
Boiler front door
Fire door on the front section
Water delivery and return lines (even if isolated), safety lines
Flue spigot
Connection between flue outlet and chimney
Circulator pumps, expansion vessels
Boiler room
1. Ensure that the boiler room has an easy access to outside in case of danger in heating system
2. Do not leave the solid fuels and auxillary substances (chips, paper etc) to ignite the boiler, with the distance less
than 800 mm from the boiler
3. Do not cover the fresh air openings of the boiler room, as it is very important for the combustion
Flue gases
1.There could be a little gas release from the front side of the boiler, when the front loading door is opened. Never
breathe this gas flow.

Firing fuel
1. Do not take the firing fuel out from the combustion chamber while it is still burning
2. Do not try to put the firing fuel off using water or any other liquids.
3. Do not leave the front doors and fire door open when there is fire inside the combustion chamber
4. To slow down or stop the fire, close air inlets, and flue outlets..
5. Your boiler can only be fired with the solid fuels whose characteristics have been given in Technical data section.
Never use any other solid fuel that would be harmfull for boiler section design, any liquid or gaseous fuels.
