Preparation

• 1). Remove the guts of the old fireplace. If there is a fireplace insert, disassemble it and pull it out. If the fireplace doesn’t have an insert, clear out all of the debris.
  
  
• 2). Insulate the fireplace chase if the old insulation is worn. The chase is the surrounding that covers the flue. The flue is where the smoke and gases are vented through the chimney.
  
  
• 3). Measure the fireplace frame.
  
  
• 4). Purchase a fireplace insert that will fit in the frame. Inserts are easy to install and output more heat without spreading harmful pollutants. Inserts also come in a variety of styles, making it easy to change or update the look of your home.
  
  

Installing the Insert

• 1). Attach the vent pipes to the mounting plate on the insert using sheet metal screws.
  
  
• 2). Remove both the chimney dampers and the ash cover. Dampers seal the flue when the fireplace isn’t being used. The ash cover should be on the floor of the fireplace.
  
  
• 3). Install and center the firebox by attaching the insert’s legs.
  
  
• 4). Run the necessary lines to the chimney, depending on the type of heat source being used. If the heat source is changing, for example, from electric to gas, call a professional to do the job.
  
  
• 5). Put the insert into the firebox and install the mounting plate onto the insert.
