A three-alarm fire that destroyed one DundalkHighshire Court fire townhome Sunday and damaged two others began when a spark from a pellet stove ignited a sofa.

The fire, dispatched at 10:27 a.m. to the unit block of Highshire Court, was investigated by Baltimore County Police fire investigators.

They and BCoFD officials said this fire illustrates the importance of not placing combustible items too close to pellet and wood stoves. The U.S Fire Administration and National Fire Protection Association recommend at least three feet of clearance.

One person was transported to a local hospital with non life-threatening injuries sustained in the fire; at least eight residents were displaced.

The fire originated in the basement of an end-of-group townhome, where the pellet stove and sofa were located.

Fire commanders called for a second alarm at 10:46 a.m. and for a third alarm at 10:47 a.m. The building of origin was evacuated at 10:51 a.m., and the other two affected structures were evacuated at 11:21 a.m.

The fire spread across the roof to the two adjacent units.

The townhome where the fire began was destroyed. The two adjacent units were significantly damaged by fire and by overhaul required by firefighters to contain the fire.
