DEVRON boilers can be fired with high quality wood pellets;
6 to 8 mm in diameter,
Moisture < 10 %,
Ash < 1 %,
Fines < 1%,
Lower calorific value > 17 MJ/kg.
Ashes must not melt and stick to each other.
You can use some other alternative solid fuels but never change fuel without qualified service
approval. Some parts can be changed according to fuel type.
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).
20x20 cm min. height 7m
Ø20 cm min. height 8m
15x15 cm min. height 11m
Ø16 cm min. height 12m
Exact dimensions of flue must be calculated according to local codes. Flue draught is specified in technical
parameters. Exhaust pipe must have the outlet into the chimney. If the boiler can not be attached to the chimney
directly, the exhaust pipe must be without heating surface and it must rise to the flue. Exhaust pipes must be tight
and resistant against flue gas leakage and clean able from inside. Exhaust pipes must not come through home and
utility spaces and the internal section of the exhaust pipe must not be narrowing to the flue. Using of 90° bents is
not suitable.
Connecting the boiler to the mains net
The boiler is connected to the mains of 230V, 50Hz by a supply cord and plug. The voltage is of M type and
when replaced, the same type must be used by a service organization. The appliance must be located in such a
way that the plug was within the reach of the attendance.
8.3. FLUE GAS EXHAUST SYSTEM.
DEVRON type boilers are B
23
type appliance so the flue gases must be connected to an adequate draught
chimney, (-1 to -6 mmWC) without any flue gas leakage to the boiler room.
