Vatican City - Vatican workers installed a simple stove at Sistine Chapel, which will burn votes during the upcoming conference match to elect a new pope.

The Holy See released a video of the May 7 meeting preparations Saturday, which included the installation of stoves and fake floors in the frescoed Sistine church to make it more actionable. The video also shows workers lined up on simple wooden tables, with the Cardinal sitting down to vote on Wednesday and there is a ramp leading to any cardinal’s main seating area in the wheelchair.

Firefighters were seen on the roof of the church on the chimney on Friday, and smoke signals would indicate whether they were elected as Pope.

These preparations led to a solemn feast at the beginning of the conference, the first successor to Pope Francis, the first Latin American pope in history, who died on April 21 at the age of 88.

The Mass at St. Peter's Basilica, celebrated Wednesday morning by Giovanni Battista Re, the dean of the Cardinal College, began, and since then, Cardinal voters have been isolated from the rest of the world. In the afternoon, they will join the Sistine Church, hear meditation and swear, and then vote again.

As of now, 133 cardinals are expected to attend the meeting. If no candidate gets the necessary two-thirds majority on the first vote, i.e. 89 votes, then these papers will be burned and the smoke will show the world that there is no pope elected.

The Cardinals will return to their Vatican residence for the night and return to Sistine Church Thursday morning, with two votes in the morning and two in the afternoon until the winner is found.

After every two rounds of vote, the vote will burn in the stove. If the Pope is not selected, mix the ballot with a cartridge containing potassium chloride, anthraxone (the component of coal tar) and sulfur to create black smoke from the chimney. If there is a winner, the ballot is mixed with potassium chlorate, lactose and chloroform resin to produce white smoke.

White smoke emerged from the chimney in the fifth vote on March 13, 2013, and Cardinal Jorge Mario Bergoglio was introduced into the world as Pope Francis was introduced shortly afterwards from Loggia in St. Peter's Basilica.

Preparations are underway to discuss the future needs of the Catholic Church and the types of pope who can lead it when the Cardinal meets privately at a more informal meeting.
