Draft Conditions - Cast Tec ALBERG 7 Installation And Operating Instructions Manual

CAUTION:
Cleaning procedure:
Discuss this with chimney sweep or qualified installer prior to or during the stove
installation.
Chimney draft:
If the chimney draft is naturally poor it is better to install the flue from the top of the
stove so as to minimise any internal resistance of the flue gases. Avoid having any more
than 2 bends in the flue system and limit the length of the offset between bends.
Fresh air supply:
A wood‐burning stove requires air for combustion and therefore you may need to install
additional ventilation to the room (ATTENTION: don't use any extractor fans or any
similar device in the same room with this product. It could make the draft too weak),
especially so in well insulated houses.
If the air supply is inadequate the chimney draft may be too weak, with the possible
result that the stove will not burn properly; smoke spillage may also occur during the
refueling process. On a positive note, a properly installed wood‐burner will give even the
most efficient houses a pleasant and natural ventilation.
2.8 Draft conditions
If smoke spillage occurs when the fire door is opened, it is probably due to poor chimney
draft. This type of stove requires at least 12 pa of chimney draft to achieve satisfactory
combustion and smoke spillage prevention. However, in cases where the stove door is
opened too vigorously you could expect that slight smoke spillage may occur. If you have
any doubts, you may want to have your installer measure the draft in the chimney.
Draft conditions
The chimney's draft is the resulting effect within the flue caused by the difference in
temperature within the flue and the cooler temperature outside. Other factors that can
influence the level of draft include the length of the flue, insulation of the chimney,
adverse weather conditions or tall buildings or trees nearby the flue terminal.
Poor draft occurs when:

The atmospheric temperature difference is too low, e.g. a poorly insulated
chimney. If the chimney is excessively cool, it may help to 'prime' the flue before
the fire is lit. Just place a screwed‐up sheet of newspaper in the flue ways of the
stove and ignite.
