Cooker is to be connected with chimney through shuttles and via connection on the back side of
cooker, in order to provide adequate sealing and smoke flow from cooker to the chimney.
Shuttle may not be installed too deeply into the chimney to avoid reduction of cross-section of
the surface thus impairing air flow in chimney. Do not use reducers which would reduce cross-
section of the smoke exhaust pipe (shuttle).
Cooker requires intake of fresh air into the room in which it is installed, whereat surface of the
opening for intake of fresh air may not be smaller then 0,4 dm². Device for intake of fresh air is
to be mounted outside collective room for ventilation which must be secured with doors and
grid.
Ventilators which work in the same room in which cooker is mounted may create disturbances
with the cooker operation. Also, all devices or air conditioning which make sub-pressure in the
room in which oven is installed must be adjusted not to make decompression which disables
normal operation of the cooker.
Prior to installation of the cooker, check air flow in the chimney since it is one of the key factors
of proper operation. Air flow depends on accuracy of the chimney and meteorological
conditions. One of the simplest aspects for checking of the air flow in the chimney is using
candle flame, as illustrated in the figure 2. Candle flame is to be offered to connection opening
of the chimney and, if it sways towards opening, air flow is satisfactory (fig. 2b). Weak swaying
of the flame is indicator of weak air flow (fig. 2a).

If air flow in the chimney is weak (Fig. 2a), check accuracy of chimney. Chimney should be
located within interior of an object, and if it’s on external walls of an object, it is recommended to
insulate the chimney.
