Therefore, proper ventilation in the room is needed and natural ventilation openings must remain
unobstructed and activating the mechanical exhaust fan/range hood. Intensive and continuous use of the
appliance may require additional ventilation, for example by opening a window, or increasing the power of
the mechanical exhaust fan/range hood, if installed.
