Boiler dimensions
5. BOILER START-UP
1.The boiler room should meet the rules shown in GENERAL BOILER
REQUIREMENTS (see point 2).
2.The boiler should be connected to the central heating system whose heating
capacity is equal of the boiler power range.
3.If the boiler is connected into the forced (pump) system it has to be protected in
case of power deficiency (boiler and pump disconnection) min. power
collection must be assured, e.g. for boiler 25 kW ca. 5 kW.
4.Boiler has to be connected to the chimney duct as shortly as possible,
a straight tube is preferred.
5.The tube connection flue with chimney should slightly rise over the chimney side
to reduce the pressure drop ( lift min. 5º ).
6.The chimney should have the section and height assuring required chimney
draught. Recommended chimney section is 20 x 20 cm.
7.Stable boiler connection to the water supply system is not recommended in case
of valve leakage it does not allow for pressure increase in boiler.
8.Boiler setting up should be carried out by qualified staff.
Each boiler is always delivered with: boiler filling up valve, room temperature
sensor and cleaning up elements.
Cleaning elements are: poker (fire iron), scraper, exchanger tube cleaner (bar ).
Remark! It is your duty to check delivery completeness.
15. BOILER EXPLOITATION
Before first boiler start-up you should check all of threaded connections (if there is
no leakage) and also water level into central heating system - then set-up boiler
working parameters.
It is recommended to be familiar with this instruction manual before boiler
setting-up.
Proper boiler burning:
1. Push the chimney flap (gas pass opened)
2. Place splinters and some bigger wood pieces using boiler upper chamber
3. Burn paper
4. Open lower door (natural draught)
5. Wait about 15 - 20 min for better wood burning
6. Place more wood to cover the boiler bottom (ca. 10 cm)
7. Switch on the master switch
8.fill up the whole boiler with wood
9.close upper and lower door
10. pull the chimney flap (gas pass closed)
11. if boiler temperature achieves 60ºC, fan begins to work
Warning! It is forbidden to switch on the fan if the upper door is opened
Important! Pay attention during boiler filling up with chunk of wood. They should be
of suitable size. Chunks bigger than required may cause door dama-
ge.
Maximum chunks dimensions:
Important! Wood has its permissible humidity when is seasoned at least 1 year.
Recommended humidity level is achieved after 2 years of wood sea-
soning.
Fuel filling up
If boiler is well-chosen, one full loading is sufficient for 6 to 12 hours of heating.
However, to avoid repeating of boiler burning it's good to check the boiler every 5-
7 hours.
