
The choice of the right boiler size, that is its heating output, is a very important condition for
economic operation and right function of the boiler. The boiler must be chosen so that its nominal output
responds to heat loss of the heated volume.
I. SAFETY ARRANGEMENTS
Heating system safety arrangements shall be designed in accordance with the type of heating system,
energy source, and the way which the heat supply is provided to the heating system, i.e. automatically
controlled or manually operated. Minimum required safety arrangement other than the present systems on
boiler is under the responsibility of the installer and must be according to local codes and/or EN 12828. This
is a manual running solid fuel boiler so special attention must be applied for correct installation and safety.
Ventum boilers has a special heat exchanger mechanism according to related standard. Be sure that it
works with the correct pressure interval(examine the following visual).
II. FUELS
VG boilers can be fired with high quality wood especially logs; 25-75 cm long, Moisture 15.. 20 %,
Never try to change fuel without qualified service approval.
Specified fuel is dried, hard, cut wood and logs of 60-120 mm diameter, with min. 15% and max. 20%
moisture content and calorific value of 15-17 MJ/kg.
Note: Logs of bigger dimensions is necessary to cut into halves or quarters (because of the
requirement of operation to nominal output). You can burn hard as well as soft wood. Wood must be dried!
Chimney
Attachment of the appliance to the flue must be always done with approval of authorized chimney
sweeping company. There must always be sufficient draft in the flue and flue gas must be draught to the
atmosphere in all possible operation conditions. For the right operation of the boiler the independent flue
must be dimensioned in the right way, the draught is influenced by the section of flue, height and roughness
of the internal wall. In to the flue where the boiler is attached, no other appliance can be attached. Flue
draught must have the specified values. But it must not be too high so as not to decrease the efficiency of
boiler and interrupt burning. If the draught is too strong, install a draft regulator to the bottom part of chimney
(60 cm below the boiler flue tube connection point).
