Gas fireplaces operate on either natural gas or propane. However, it is recommended to use pure propane instead of a propane-butane mix. This is because when burning a propane-butane mix, the propane burns first, and the butane phase (which is “dirtier”) can quickly cause soot buildup on the fireplace glass.
Gas Quality is Crucial
The soot problem is easily manageable as the glass can be removed and cleaned, but it’s not something users want to do frequently. Therefore, having a reliable propane supplier who guarantees clean gas is essential. Ideally, if there’s a natural gas hookup, it eliminates the need for gas tank changes and ensures a cleaner burn.
Safety First
Gas fireplaces are equipped with numerous sensors that will shut down the unit if any irregularities are detected. Additionally, gas detectors can be installed during setup to trigger an alarm in case of a gas leak. The amount of gas detected by these sensors is not enough to cause an explosion, ensuring a high level of safety.
Exhaust and Venting
Gas fireplaces do not produce much more exhaust than a typical gas stove. However, they are classified as appliances that require a vent (chimney). This has no negative impact on health, as the only thing emitted into the room is heat.

If a chimney is not already present (as in many apartments), a coaxial vent pipe system is used. These pipes consist of two layers: the inner pipe supplies fresh air to the fireplace, while the outer pipe exhausts combustion gases.
Installation and Planning
Ideally, the gas fireplace installation is planned during construction or renovation to ensure gas lines can be accurately placed, making the installation straightforward. If this is not possible, careful planning is required to conceal the vent pipes, especially if they need to cover a longer distance.
If natural gas is unavailable, planning a suitable location for the propane tank is crucial to ensure easy access for replacement while maintaining the room’s aesthetics. Generally, a space of about 16×16 inches with a height of around 26 inches is needed for the tank. These tanks can be effectively concealed while remaining accessible. The fireplace’s automation typically runs on batteries, which are rarely changed, but it can be connected to the house’s power supply if desired, necessitating a nearby outlet.
Freestanding Gas Fireplaces
Freestanding gas fireplaces do not require any external finishing or decoration and are often considered “furniture.” They come with built-in casings made of black or white glass or powder-coated metal in various colors. The installation and connections are the same as for built-in models.
Converting a Traditional Fireplace to Gas
For those who already have a traditional fireplace but want a simpler alternative, gas inserts are an excellent option. These inserts can be connected to an existing chimney and either a gas hookup or a propane tank. This way, users retain the cozy atmosphere of a fireplace without the hassle of maintenance and cleaning. These inserts are also more affordable than other gas fireplace options but require an existing chimney to be used indoors.
Outdoor Use
These inserts can be placed in any housing and make a great addition to backyards or patios. Gas fireplaces for outdoor use can also be used on apartment balconies, as long as the height is sufficient.
