WARNINGS
– The smoke flue and the connection to the flue pipe must be in compliance with the national and local standards and
legislation in force in the country where the appliance will be used.
– The use of rigid ducts which are resistant to temperature, condensate, mechanical stress and are air-tight is compulsory.
– Outlet ducts which are not isolated are a risk of danger.
