Albert Barnes Commentary 2 Chronicles 7:1

"Now when Solomon had made an end of praying, the fire came down from heaven, and consumed the burnt-offering and the sacrifices; and the glory of Jehovah filled the house." — 2 Chronicles 7:1 (ASV)

The fire came down from heaven - This was just as in the time of Moses at the dedication of the tabernacle (Leviticus 9:24). This fact is omitted from the narrative of Kings, but omission is not contradiction.
