Gas fireplace inserts operate by burning natural gas or propane to produce heat and flames. They are typically vented through the existing chimney, although some models can be vent-free. Here's a simple breakdown of how they work:

  • Gas is supplied to the insert through a flexible gas line connected to your home's gas supply.
  • When you turn on the insert, gas flows into the burner assembly, where it's ignited to produce flames.
  • The flames heat the firebox, which in turn heats the air in your room. Some inserts also feature a blower to circulate the warm air more efficiently.
  • The combustion process produces exhaust gases, which are vented out through the chimney.
