Leviticus 1:9

‘Then he shall remove all its fat, just as the fat was removed from the sacrifice of peace offerings; and the priest shall offer it up in smoke on the altar for a soothing aroma to Yahweh. Thus the priest shall make atonement for him, and he will be forgiven.

He also brought near the burnt offering and offered it according to the legal judgment.

“And you shall offer your burnt offerings, the flesh and the blood, on the altar of Yahweh your God; and the blood of your sacrifices shall be poured out on the altar of Yahweh your God, and you shall eat the flesh.

In the porch of the gate were two tables on each side, on which to slaughter the burnt offering, the sin offering and the guilt offering.
