The fireplace includes a hearth suspended on a support. The hearth is defined laterally by a peripheral wall that is equipped with at least one combustion air inlet. There is a discharge pipe for discharging the combustion gases, that includes a bottom portion secured to a top part of the hearth, and a top portion opposite the bottom portion. The fireplace also includes at least one combustible fluid burner that is arranged in the hearth opposite at least one air inlet and a combustible fluid supply column that extends between a first end connected to a combustible fluid source and a second end connected to at least one burner. The supply column passed down through the discharge pipe from its top portion to its bottom portion and opens in the hearth in order to convey the combustible fluid from the combustible fluid source to at least one burner.
