Two firefighters suffered minor injuries in a blaze caused by a defective fireplace in a Massapequa house Sunday morning, fire and police officials said.

Firefighters rescued the resident’s dog after responding to the fire at the Bayview Avenue home around 10 a.m. Sunday Massapequa fire department chief Gerard Keuchler said.

“We found the dog hiding underneath the bed in one of the bedrooms,” Keuchler said. “He was a little scared but he’s alright.”

The firefighters were treated at the scene for minor injuries. A woman inside the house was not injured, he said.

Nassau County police department arson and bomb squad detectives determined that the fire was accidental and caused by a defective fireplace, according to a news release. Keuchler said the fireplace had been in use but the frigid weather Sunday was not a factor.

Six firetrucks and 50 firefighters responded to the blaze which took about 15 minutes to control, he said. The fire was contained to the living room of the one story house which sustained extensive smoke damage, he said.

Also Sunday, a house fire destroyed two rooms and damaged another in Albertson, according to a fire official. No one was injured in the blaze, Albertson First Assistant Chief Joel Melamed said.

A couple at a two story house on Barry Park Court smelled smoke from the second floor and came downstairs to find a den and bedroom on fire, he said.

The couple left and called the fire department at 1 p.m. Four fire companies and 75 firefighters responded and the fire was under control in about 15 minutes, Melamed said. The cause of the fire, which was believed to have begun in the den, was under investigation Sunday, he said.
