Gas fire Image - Royal Oak MI - FireSide Heath and HomeGas fireplaces seem simple enough. You flip a switch, or press a button, and the fireplace ignites, adding a gentle glow and a cozy heat to your living space. But how does your gas fireplace really work? We’ll explain the anatomy of a gas fireplace to help you understand your home-heating appliance a little better.


All fireplaces contain a firebox. In a gas fireplace, the firebox is a sealed unit, usually with glass doors to showcase the flickering flames and radiate heat from the fire itself.


The fire itself is the fireplace burner. Some burners are ignited by a pilot light, while others feature electric starters that light the fire quickly and efficiently. Logs usually sit atop the burner to add a decorative element, and they can be left out entirely or replaced with glass stones or river rocks for a sleeker, more contemporary look.

Convection space

While it may look like your gas fireplace is firmly enclosed in your hearth, there is actually an area of dead space around the fireplace that allows air to circulate to help heat your home. The cooler air from your living space is drawn into the lower vent of the fireplace. It travels around the firebox, and as it does so, it picks up heat, rises and then exits through a top fireplace vent. In some gas fireplaces, an electric fan helps to circulate the warming air.


There are three types of gas fireplaces, and what sets them apart is how they are vented.


Many gas fireplaces are wired to a thermostat within the home. That means you can control the heat output of your fireplace to meet your home-heating needs.
