INSTALLATION
DISCHARGE OF THE PRODUCTS OF COMBUSTION
The flue and the flue stack fitting must be made in compliance with the
standards and the legislation in force, using rigid pipes that are resistant
to high temperatures, condensate and mechanical stress, and are air-
tight. The flue stack must ensure the minimum negative pressure speci-
fied by the standards in force, considering “zero” pressure at the fitting to
the flue. Unsuitable or incorrectly sized flue stacks may increase the
noise produced due to combustion, generate problems involving con-
densation and negatively affect the combustion parameters. Non-insu-
lated flues are a source of potential danger. The joint seals should be
made using materials that can resist temperatures of at least 250°C.
Suitable points for measuring the flue gas temperature and analysing
the products of combustion must be prepared in the connection betwe-
en the boiler and the flue stack. As regards the cross-section and the
height of the chimney, refer to the national and local standards in force.
