If there is a direct connection with the outside it must be endowed with a special windbreak.The air entrance for combustion into the installation place must not be closed during the operation of thestove. It is absolutely necessary that in the environment in which the stoves operate with the natural flue ofthe chimney, it is introduced as much air as necessary for the combustion, i.e. up to 20 m3/hour.The natural recirculation of air must be ensured by some fixed openings on the outside.
