7.4. Connecting the boiler to the mains power supply

ATTENTION! HIGH VOLTAGE!
Make sure the regulator is disconnected from the
EN
+
mains before working on the power supply (cable
connections, device installation, etc.)! Make sure
the electrical power grid is grounded.
* Such connection must be performed by a technician
/ service shop authorized for such operations.
* Improper cable connections may damage the
regulator!
* The device may be damaged if struck by a lightning.
Make sure it is unplugged during the storms.
It is mandatory to assure a backup power generator
*
of corresponding rated power! (see 12.2)
The boiler must be connected to a 220V / 50Hz mains using
a cable and a plug. The boiler must be placed in a position
which allows for unobstructed access to the power supply
plug. Dismount the inspection cover on the back side of
housing.
Using a screw driver, connect the power supply and the
external components (pump for the heating circuit and
domestic hot water pump). Make sure you have connected
the external components properly according to the enclosed
wiring diagram.
Create solid connection with the electrical mains which
complies with the local regulations.

Prevention
Make sure all conductors are placed
in the required cable guides and pass
over the thermal insulation of the
boiler.

8. FILLING THE HEATING INSTALLATION

Problem
Possible installation damage
due to strains in the material
caused by temperature
differences
Danger of installation
damage due to accumulation
of deposits. Condensate
formation and tar deposits
may shorten boiler's
operational life.
9. BOILER OPERATION

9.1. Loading and ignition the boiler

When ignition the boiler for the first time, a condensate
is formed which is later drained (this is not a fault in the
boiler).
Fuel is loaded in the upper combustion chamber and it is
recommended to load logs of length equal to the combustion
chamber length and stack them tight inside with least
possible air gaps. Both boiler doors should be well closed
and sealed. Switch ON the controller. Set Maximum boiler
temperature. Use a gas analyzer to adjust the fan power
(speed) and the chimney draught.
When burning moist wood, the boiler stops working
effectively and this has the following consequences:
- significantly increases fuel consumption;
- not reach the desired power;
- lifetime of the boiler and chimney fall.
* Maintain operating temperature between 65° C
and 80° C.

9.2. Cleaning of the boiler

Caution! Hot surfaces.
*
Before cleaning the boiler, make sure the fire in it has
died out and the boiler has cooled down.
Boiler cleaning must be carried out periodically and
adequately every 3 to 5 days. Ash accumulated in the
combustion chamber, condensed moisture and tar deposits
significantly reduce the life span and performance of the
boiler and result in deterioration of the properties of the
heat exchange surface In case of larger ash accumulation
there is not enough space for fuel combustion which may
result in damage of the boiler as a whole. Regular cleaning
is important to ensure the optimal performance and long
operational life of the boiler.
At the start of the new heating season is recommended
cleaning the boiler by a competent service.
It is recommended that the ash-and soot-container be
emptied and cleaned every 3 to 5 days depending on fuel
used. Scrape the inside of flue pipes if necessary. Use the

Prevention
Fill the heating installation
only in cold conditions (inlet
temperature must not exceed
40°C).
- Do not operate the heating
boiler for a long period of time
in partial load mode
- The temperature at the boiler
inlet must not be less than
65°C, boiler water temperature
must be between 80°C and
85°C.
- Use the boiler for a short
period to heat warm water in
the summer.
