NOTE:
It is recommended to install an outside air inlet with a diameter of at least 4 inches 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 furnace is responsible for the room’s air quality in case of negative pressure or
temporary negative pressure.
For more information regarding the installation of fresh air intake adapter, refer to the option’s manual.
