The house fire at 1645 S. Elm early Wednesday morning has been deemed accidental, Ottawa fire officials said.

Ottawa Fire Department fire investigators along with the Kansas Fire Marshal’s office conducted an extensive investigation into the cause and origin of this fire, officials said. The results of the investigation determined the origin of the fire was in the living room of the home. The cause of the fire is undetermined.

Zach Malburg, 24, Ottawa, shared the home with his mother, Kim Hanvy. As of Thursday morning, Malburg was listed in stable condition and improving at a Kansas City hospital, fire officials said.

Information released Wednesday that the residential smoke alarms did not sound was incorrect. After further investigation and listening to the 911 call made by the Malburg, investigators heard a smoke alarm sounding. Talking with family Thursday morning, Mr. Malburg stated that he was awakened by a smoke alarm.

Ottawa Fire Department wants to remind residents to check their smoke alarms every month and change the battery at least once a year or whenever the smoke alarm makes a chirping sound. The chirping sound is to notify the occupant that the battery is getting low. Plan your escape and practice fire drills in your home at least twice a year.

All fire departments within Franklin County, including Ottawa, have smoke alarms to give to citizens free of charge. Please stop by your local fire department and get smoke alarms if needed.
