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.
8.1.3 HIGH TEMPERATURE SURFACES
Avoid contact with parts and surfaces having high temperatures (working surfaces) which will
be hazardous for human such as:
1.
Boiler front door
2.
Fire door on the front section
3.
Water delivery and return lines (even if isolated), safety lines
4.
Flue spigot
5.
Connection between flue outlet and chimney
6.
Circulator pumps, expansion vessels
8.1.4 FLUE GASSES
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.
2. When adding solid fuel when there is active fire bed inside the combustion chamber,
protect your hands and face. If needed wear protective gloves.
8.1.5 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

9 MAINTENANCE
AND
CLEANING
9.1 PERIODIC
INSPECTIONS
•
Check the water level or pressure. The hydrometer must be marked after first filling of
the boiler. So, water level can be checked regularly. If the water level or pressure is
under the level of static pressure or the system set-up, a water make-up is needed.
The make-up water should be softened according the local regulations before feeding
into the system to prevent corrosion inside the heating circuit and the boiler.
•
Front doors of the boiler should be checked for properly closing. Fibre-glass ropes must
be replaced if necessary. Check the condition of refractory inside the front door. If it is
damaged, you will have higher surface temperatures on front doors. In this case the
refractory should be replaced to save energy and prevent further crack.
