Rinshan kaihou 「嶺上開花」 is a standard yaku, where a player wins with the rinshanpai, or the replacement tile after forming a kantsu. As such, this yaku is only accessible via kan calls.
Meaning
Rinshan kaihou literally means "flowering 「開花」 on the range 「嶺上」". In a sense, the dead wall is treated or viewed as a "mountain", where the winning tile after the kan draw symbolizes as a "flowering" effect.
Kan procedure
When calling kan, a player must draw an extra tile; and that tile comes from the dead wall. This is the rinshanpai 「嶺上牌」. If the hand is completed with this tile draw, then this yaku is awarded. It is quite possible for rinshan to be the only yaku for the hand. Usually, players already have other yaku.
Setting up rinshan kaihou
Like any hand, this yaku requires tenpai to even have a chance of winning. This is particularly true when kan is involved. As such, the fourth tile for kan counts as an extra tile. If that tile is in the hand, it actually takes up one tile space, that could be used for normal hand development.
Tenpai, with chance for rinshan:
Draw: 
Waiting for: 
In order for this hand to proceed to tenpai, either kan must be called or one of the hatsu is to be discarded.

Rinshan kaihou is generally compatible with any hand, that can accommodate kan calls. This rules out any yaku dependent on all sequential tile groups, namely both pinfu and ryanpeikou. Other yaku, such as sanshoku and ittsu, are also sequential based, but they have room one triple tile group to be upgraded for a kan call. By definition, chiitoitsu requires every tile pair to be unique; so kan calls cannot be performed here. With chankan, this yaku uses another player's kan call rather than one's own.
With haitei
Rinshan kaihou cannot be combined with haitei, a yaku for calling tsumo on the final tile from the live wall. When winning on the replacement tile after a kan, tsumo is not called on any tile from the live wall, but on a tile from the dead wall.
Sekinin barai
Some rule systems impose a liability payment, called sekinin barai or pao, on the discarder of a kanned tile in the event of a rinshan kaihou win.
If this rule is in effect, whenever a player starts his turn by calling kan on a discard, the discarder is liable for the entire price of the caller's hand until end of turn. If the caller calls tsumo on the replacement tile after the daiminkan, payments occur as if he called ron against the liable player. If the caller continues to make ankan or shominkan on the same turn, then wins on a replacement tile, payments again occur like a ron against the liable player. When the caller discards a tile, the discarder of the kanned tile is no longer liable.
