made of non-combustible material protected against oxidation (e.g. enamelled steel flue pipe). If the
chimney produces poor draught, consider laying new flues. It is also important that the chimney does
not produce excessive draught, in which case a draught stabiliser should be installed in the chimney.
Alternatively, special chimney finials are available to regulate the draught. Chimney flue inspection
The chimney flue should be inspected by a master chimney sweep and any alterations may be carried
out by an authorised company so that the requirements are met.
Connection to the flue pipe must be carried out in accordance with the standard. The minimum effec-
tive height of flue flues is 4-6 mb.
The length of the connection between the appliance and the chimney should not exceed 1/4 of the
total height of the chimney.

VENTILATION IN THE ROOM WHERE THE COOKER IS INSTALLED
The room in which the cooker is to be installed must have a volume resulting from the ratio 4 m 3 x
1 kW of nominal heat output of the appliance, but not less than 30 m3. In addition, it should have an
efficient ventilation system and provide the necessary amount of air required for the correct operation
of the stove. It is assumed that approximately 8 m3 of air is needed to burn 1 kg of wood. The room in
which the cooker is to be installed, which draws air from the room, must be free of extraction devices
and other appliances with a hearth. In rooms with mechanical ventilation or very tight window frames,
an individual air supply to the combustion chamber must be used. Ideally, a fresh air intake from the
outside should be used for this purpose. The combustion air intake should be selected so that it cannot
become clogged. Efficient combustion is guaranteed by connecting the intake of outside air. The inlet
grilles of the room ventilation system should be secured against self-closing.
SAFETY SETTING OF THE COOKER - DISTANCES
The fireplace should be placed on a non-combustible floor of at least 20 - 30 mm thickness. The flam-
