Some hold the Menorah is lit inside, some hold it should be lit in a doorway, some hold by the window and others hold outside.
For those who hold the Menorah is situated at a doorway, on the side opposite the Mezuzah. If there is no Mezuzah, such as in a hotel, the Menorah is placed at the right side of the door. [If the Menorah was placed on the wrong side, one has still fulfilled his obligation.]
The Menorah should be placed within the actual doorway, as close to the doorpost as possible. [If this is not feasible, it should at least be placed within a Tefach (8cm) of the doorway.] It does not matter if the flames span north-south or east-west.
It is preferable to use the doorway of the room where one eats, as opposed to the doorway of the room where one sleeps.
Although it is preferable for the head of the household to light at the main eating area, nevertheless, each child should light at the entrance to his personal bedroom, unless there are safety concerns.
When more than one person lights at the same venue, each set of flames should be noticeably distinct from the others. In practice, this is easily accomplished when everyone uses a separate Menorah. However, when two people improvise by sharing the same Menorah (e.g. during the first nights of Chanukah), or by not using a Menorah at all, there should be a clear gap between each set of flames.
Those who have the custom to light in the window should make sure it is safe to do so. The Menorah should be lit facing the street rather than the back of the house. It should be lit on the right side of the window. Some have the custom to light outside on the edge of their property closer to public property.
If one regularly lights outside, yet someone gave them a new silver Menorah, in fear of it being stolen one should rather light their old Menorah outside.
Those in a Yeshivah dormitory, seminary or at an overnight camp should follow the instructions of their Hanhalah.
The Menorah is situated so that the flames are anywhere between 3 Tefachim (24cm) and 10 Tefachim (80cm) from the floor. If the Menorah is placed higher, it is still acceptable (unless the flames are higher than twenty Amot – 9.6 meters). A large Menorah which is taller than 10 Tefachim may be used even in the first instance.
The Menorah must not be situated in a place where there is a strong possibility that it will be extinguished, e.g. by winds or vandals.
