BEATRICE, Neb. (AP) — A man has escaped from a fire that heavily damaged a house in southeast Nebraska.

The fire was reported about 2:30 a.m. Tuesday in Beatrice. Fire Chief Brian Daake said firefighters suspect the blaze began on the east side of the house.

Daake says a state investigator found that the fire began in the chimney pipe of a wood pellet stove. The investigator determined that there was a blockage in the chimney pipe.

No injuries have been reported to the man who escaped. His name hasn’t been released.
