Handbook of Liturgical Practice of the Russian Church Abroad
The standing candle is lit just prior to the Bishop’s arrival in the Temple, and remains lit until he departs.
Its normal place is in front of the icon of the Theotokos on the north side of the Royal Doors, and where ample Altar servers are available it is held their throughout the entirety of the Liturgy (up until the doors are closed for the communion of the clergy).

This standing candle is brought to the entrance of the Temple for the greeting of the Bishop. A server carries it and stands with it during the greeting (with the Deacons, holding the trikiri and dikiri, facing the Bishop); then, when the Clergy and the Hierarch process to the amvon for the Entrance Prayers, the candle-bearer takes the candle ahead of them, replaces it before the icon of the Theotokos (i.e. in its usual place) and himself re-enters the Altar, retiring from any further activity until the beginning of the Hours (or, where ample servers are available, it remains being held there throughout, while the zhezl is held on the opposite side of the Royal Doors).
