The famous chimney, which will mean the world for the choice of a new Pope, was installed on the roof of the Sistine chapel next week before the final.
Vatican firefighters fixed the chimney, which is an essential moment in preparation for the vote on May 7th to name the successor to Pope Francis.
After two rounds of voting in the Sistine chapel, the cardinals' ballot papers are burned in a special oven to display the results on the millions that observe reporting on the Rolling messages around the world.
If no new Pope has been selected, the ballot papers are mixed with potassium perchlorate, anthraces (a component of coal tea) and sulfur to generate black smoke. But if there is a new bishop of Rome, the ballot papers are mixed with potassium chlorate, lactose and chloroform resin to create white smoke.


It was only in the fifth ballot on March 13, 2013 that the white smoke from the chimney rose to the successor of Pope Benedict XVI after the election of Cardinal Jorge Mario Bergoglio.
The Argentinian, the first Pope of History from Latin America, was introduced a short time later from the loggia of St. Peter's Basilica in the world as Pope Francis.
This year's conclave takes place after his death at the age of 88 on Easter Monday.
What is a conclave and how does it work?
After the death of the Pope, the chairman of St. Peter is freely explained – free in Latin.
The papal funeral is celebrated within four to six days, followed by mourning and special masses.
During this time, cardinals from all over the world who have traveled to Rome gather for a series of meetings known as “general communities”.
While all cardinals can take part in these discussions, only the under 80 years of age can vote for the new Pope in the Sistine Chapel.
As soon as the oath of confidentiality is stored, the master of liturgical ceremonies gives order 'Outside all'(All out) and everyone who does not take part in the conclave leaves the frescoed walls of the chapel.
An older cardinal remains and reads a meditation about the properties that a Pope should have and the challenges that the church faces. After that, he and the master of ceremonies leave the cardinals to start voting.

On the first day, the cardinals take part in an opening mass, and in the evening there is a first voice, which is often accepted as a symbolic survey in which the voters call someone for whom they have special admiration.
From then on there are two sessions every day – one in the morning and one in the afternoon – two voices each.
The cardinals are instructed to mask their own handwriting while a card is inscribed.Get the highest Pope” -” I choose the top Pope “.
They approach the altar one after the other and say: “I call my witnesses, Christ, the Lord, who will be my judge that my voice is given to those who think before God should be chosen.”
The folded ballot is placed on a round plate and hit into an oval urn.
After the voices were counted and the announced results were announced, the papers are combined with a needle and a thread, with each ballot pierced through the word.output'.
Then they are burned with a chemical to get black smoke (which means that no new pope) or knows (which was chosen, a Pope was chosen) from the chimney of the Sistine chapel.
Since then, cardinals have arrived in Rome in order to take part in pre-concrete discussion-called general communities about the needs of the Catholic Church in the future.
These consultations include all cardinals, including those over 80 years that are not justified in the conclave itself.
In the past few days, they have heard reports on the bad financial situation of the Vatican and had the chance to talk individually about priorities and problems that they perceived in Francis' pontificate.
Francis viewed some as a somewhat split pope.
Some admired his focus on the arms and marginalized, but others criticized him to sow “confusion among believers” in questions of morality and church law.
These conservative and traditionalists, of whom they are not accepted that they have the majority among the 135 cardinal voters, hope that a new Pope will reinforce the teachings of the core church again and act as a stabilizing figure in the Vatican bureaucracy.
