Take care not to feed more wood or brown coal briquette than needed for nominal
heating capacity.
The abovementioned fuel quantity must not be exceeded or else the cook-stove may
overheat.
Only naturally dried wood or brown coal briquette can be used according to the
Regulation on Emission Protection.
The wood that is used must be dry (moisture content less than 20%). That is usually the
case when wood is stored for two years in dry place with good ventilation. Wet wood has
small calorific value and causes formation of soot deposits in flueways and chimney.
Wood with surface treatment (lacquered, painted, veneered or impregnated, plywood,
waste of any kind, like packaging waste, plastic, newspaper, rubber, leather, fabric etc.)
must not be fired.
Combustion of such materials contaminates the environment and therefore it is forbidden
by law. Moreover, masonry chimney may be damaged. In such case, all kinds of
warranties given by the manufacturer shall be cancelled.
Under the adverse chimney draught conditions, disturbances may occur so that flue gases
are not completely discharged. In such case, fire shall be made as a “decoy” to masonry
chimney. If this does not help to establish chimney draught, than the operation of cook-
stove is forbidden for safety reasons.
Note:
Better efficiency of fuel and hence better space heating is achieved by opening the
oven door, slightly or completely.
