You can place your heater anywhere in a room but just make sure that all furniture and other objects are at least three to four feet away from it. This will prevent any fire hazards.
Also, don’t place your heater against the wall. Always make sure that there is a space of at least four to five inches between the wall and the heater.
Furthermore, don't place heaters in enclosed spaces as this can be very risky. Make sure you’re placing your heater in an open space where for sufficient ventilation.
Lastly, make sure you’re placing your heater somewhere it can’t easily tip over and fall. Keep it in the corner of the room with some free space around it.
