Boiler installation and connection should be carried out by a specialized, qualified
installer and be subject to applicable standards.
10. FILLING THE BOILER WITH WATER
Before you light the boiler, the central heating system and the boiler itself should be
filled with water, whose hardness should not exceed 2°n.
NOTE It is not allowed to fill up the boiler with cold water during its operation
when excessive water loss is found. Adding cold water on hot boiler walls
is dangerous for operators and can cause a very serious failure. It is
allowed only when the boiler is cooled down. Removing glowing embers
from the boiler is allowed only when the person removing them ensures the
assistance of another individual to be protected in case of fainting or other
incidents.
11. LIGHTING THE BOILER
The initial startup (lighting) after the boiler is installed can be carried out only
by a competent and authorized service technician. Failure to observe this requirement
may void your warranty. This must be confirmed by a signed and completed boiler
installation acceptance report (annexed to the warranty).
Note:
Before you startup the temperature control, the installer should check and adjust the
following boiler operating parameters (specified in a separate temperature control operation
manual).
boiler operation temperature should be set to 80°C ,
circulation pomp switch-off temperature should be set to 65°C,
fan power should be set: about 40%.
Each subsequent boiler lighting operation carried out by the user during boiler use
can occur only if you make sure that the installation includes enough water and has not
frozen.
The sequence of lighting operations:
1. Open the boiler furnace (bottom) door.
2. Clean the grate (if necessary, also the burner)
3. Load the kindling onto the grate (paper, small pieces of dry wood) and then larger
pieces of dry wood up to 1/2 of the chamber volume.(see Figure No.1) Kindle the
kindling.
NOTE! It is recommended to use „mild” wood type like pine when required
level of fire is needed fast. “Hard” wood type like oak, acacia are recommended
for refueling, because these types of wood are burned much longer.
The kindling should be carried out slowly, with the fan off and the bottom door
(about 1 cm) ajar. When the chimney is cold, and consequently the draft is poor,
you can temporarily open the by-pass device(in order to avoid smoke).
4. After a dozen or so minutes, when glowing embers will be generated up to the
burner top,(see Figure No.2) open the by-pass device, close the furnace door
and open the fuel loading door. Fill the boiler up with fuel,(see Figure No.3). Close
the fuel loading door and then the by-pass device.
