Clean the chimney at least once a year.
The most effective cleaning method for the chimney ducts is using appropriate
chimney brushes. There are chemical products which help to postpone the need for
cleaning with brushes.
The brushes must be as close as possible in size to the diameter of the chimney.
The joints between the tubes making up the chimney, in the event of being simple
metal tubes, must be sealed with fireproof filler.
The female part of the tubes must always point upwards in order to prevent the
creosote that forms from being emitted.
Outdoor metal chimneys must be built with double thermal insulated tubes
designed specifically for solid fuel.
5.1.5. Assembly with existing chimneys.
When existing chimneys are being used, it is advisable to place one or two metres
of metal tubing inside the chimney, ensuring that the opening between the built-in
chimney and the tubes is sealed.
