Can You Use Your Gas Fireplace During A Power Outage?

Power outages are never convenient, but they can be particularly troublesome during the colder months. Not only do you lose access to lights and everyday electrical appliances, but your home's heating system may stop working, too. That's where a gas fireplace can help. It runs on natural gas or propane and can potentially be used as a heating alternative until the power returns. The problem? Not every gas fireplace can start without electricity, so it's important to know which type of ignition system yours has before deciding whether it's safe to use during a power outage.

If, for instance, you have a gas fireplace with an older standing pilot (millivolt) system, you're in luck. These systems can be used during an outage, as they do not need electricity to ignite the fire. Many newer gas fireplaces, however, are a bit different. They have an intermittent pilot ignition (IPI) system that relies on an electric spark. Without power, the fireplace won't ignite. Don't worry just yet, though! Some IPI systems also have a battery-powered backup module. If, however, your fireplace doesn't have any of these, you will have to look into some other options to heat your home while the power's out.

It is also worth noting that some gas fireplaces rely on power-venting systems and use an electric fan to move combustion gases outdoors. So, while you might be able to start your gas fireplace during a power outage, its electric parts like the blower fan and power venting won't run, and the fireplace may put out less heat. If you don't have a fireplace yet, these are just a few of the things to keep in mind before adding one to your home.

If your gas fireplace does have a battery backup, the first thing you must do is find out what type of batteries it uses and keep a spare set readily available so you can install them and get your fireplace running if a power outage catches you off guard. You can usually find this information in your owner's manual. If you don't have the manual, locate the battery compartment instead. It might be located underneath the fireplace, behind the control panel, or inside a separate wall-mounted control box. Once you've found it, check which type of batteries it takes.

Just keep in mind that this battery backup is only meant for emergencies, and you should not leave batteries installed in it all the time. They'll drain over time, and heat from the fireplace can even cause them to leak, leaving you without a backup the next time you need one. Also, do not mix old and new batteries. This can reduce performance, which is the last thing you want when an emergency arises.

It's also important to take some safety precautions when using your fireplace during an outage. If your fireplace is power-vented, don't use it during an outage unless the owner's manual says it's safe to run without the fan. Direct-vent fireplaces and inserts installed in an existing chimney, on the other hand, can vent safely without one. Similarly, never leave the gas fireplace running unattended, and keep curtains, blankets, furniture, or anything else that can catch fire away from it. Lastly, get your gas fireplace serviced at least once a year so it's ready to go in case there is a power outage.
