NOTE:
It is recommended to install an outside air inlet with
a diameter of at least 4" in the room where the
heating appliance is installed (see drawing below).
It is preferable to choose a wall which is not
exposed to dominant winds, depending on the
conditions surrounding your house.
N.B. The owner of the add-on is responsible for the room's air quality in case of negative pressure or
temporary negative pressure.
If there is a fan in the wood storage room, make sure it does not create a depression in the room where the add-on is
installed.
For more information regarding the installation of fresh air intake adapter, refer to the option's manual.
