Before starting the installation, it is important to choose the air inlets and outlets
that will be used for the convection system.
A minimum of two intakes and outlets must be connected. Air inlets are located in
the lower part of the fireplace. Favor the connection under the fireplace. In the case
of a low installation, the bottom pre-cuttings on the sides can be used. For the hot
air output we recommend using the top back outlets.
For all questions concerning a non-standard installation,
contact Stûv America customer service.
