Astra P-8 USER MANUAL
• The joints of chimney pipes must have temperature resistant gaskets in order to ensure sufficient tightness of the connections;
• A separate chimney is mandatory for the Astra stove installation. It is not permitted to connect the stove to a shared flue;
• The connection of the air intake tube of the stove to an outside is not obligatory. If the air for combustion is taken from inner spaces
of the house, these must be ventilated so that up to 40 m
3
of air inflow is ensured;
• Do not use a mesh on the top of a chimney because it can reduce draught and cause problems for the stove functioning;
• When designing the chimney piping for the stove, do not use more than 3 pieces of 90° bends. The biggest distance between the
adjacent bends must not exceed 2,5 meters horizontally;
• A minimum distance of 10 cm should be left from the rear stove panel to the wall. A 20 cm free space must be left from lateral sides
of the stove and 150 cm- from the front side.

Ashes accumulate in the 90° bend
• PATTERNS OF INSTALLATION
A 90° bend should not be installed as the first
connecting part – ashes would quickly obstruct a
passage for smoke causing unexpected problems
for draught of the flue (Fig 4).
This type of installation (Fig. 3) requires an
insulated flue, as the whole smoke pipe is
installed outside the house. A chimney tee with
an inspection cap and condensate drain pipe is
mounted in the lower part of the flue.
