Removal
To remove the Flame Altar, interact with the Flame Altar, select the "Extinguish Flame" option, and then confirm. The Flame Altar starts a 30 second timer (during which the removal can be cancelled) and then disappears. Built structures, placed items, terrain changes, and so on will remain in place until the area resets normally - i.e. 30 minutes or server restart. Placing a new altar before the reset will protect the area again, but the new altar will not inherit any size upgrades applied to its predecessor. The Flame Level remains a global constant even if all Flame Altars are extinguished - it will not "go down" in level.
Renaming
To rename a Flame Altar, interact with the Flame Altar, press "R" key, and put in a new name for this specific altar.
