Anatomy of a gas fireplace

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.
A direct-vent gas fireplace has grown to be the most popular type of gas fireplace. With a direct-vent gas fireplace, the fireplace has two vents that feed directly through a wall or roof to the outside. One vent pulls in outside air to fuel the fireplace’s combustion, while the other vent exhausts the fumes and byproducts of the fireplace. Direct-vent gas fireplaces are one of the most efficient types of home-heating appliances.
Traditionally, gas fireplaces featured a B-vent flue. With a B-vent gas fireplace, the air that fuels the fire is drawn in from within the home, and the smoke from the fireplace exhausts out of a B-vent flue through the top of the home. B-vent gas fireplaces have become problematic in newer, air-tight homes because there is not sufficient air flow within the home to adequately fuel the fire.
Vent-free gas fireplaces. As the name suggests, vent-free gas fireplaces have no flues. They draw in air from the living space to feed the fireplace’s combustion. Vent-free gas fireplaces are extremely efficient, meaning they emit very little byproduct. They do release safe levels of gases and water vapor into the home as they burn.


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.

Fortunately, you don’t have to make the decision on your own! Let the fireplace experts at FireSide Hearth & Home help you choose your new gas fireplace. As you begin to weigh your options, there are a few things you will need to think about to help us find you the right fireplace.

What do you want from your new gas fireplace?

First, you will need to determine what you want to get out of your new gas fireplace. Are you looking to upgrade your home’s décor? Do you want to increase the energy efficiency of your home by using your new gas fireplace as a source of heat? Would you like to decrease the environmental impact of an existing, inefficient fireplace? Once we understand what you’d like to get from your fireplace, we will be able to narrow down the types of fireplaces you should consider.

How will you vent your new gas fireplace?

Of course, when you consider a new fireplace, you will have to consider how to vent it. With gas fireplaces, you have three primary options. If you have an existing hearth, a gas fireplace insert can be installed and vented through your existing chimney. If your fireplace will be located on an exterior wall or with easy access to the roof, you can consider a direct-vent fireplace. Direct-vent gas fireplaces use one pipe to pull air in from outside to help fuel your fire and another vent to exhaust all of the fireplace’s gases. If you are installing your fireplace in an area that is inconvenient for a chimney or vent, you can explore a vent-free gas fireplace. Vent-free gas fireplaces can be installed nearly anywhere in your home.

What features do you want in your gas fireplace?

The newest gas fireplaces come with a variety of features. They can be remote controlled for easy use. They can be wired to a thermostat to help keep a constant temperature in your home. Some gas fireplaces feature adjustable fans that can help control the flow of heated air into your home. Knowing which features are most important can help you narrow down your search for the right gas fireplace.

What style fireplace are you looking for?

They can be traditional and classic, closely modeling the look of a wood-burning hearth. You can choose an unconventional shape, such as a circle or elongated rectangle.
