As technology advances, heating appliances like a fireplace upgrade their features and functions. Traditionally, there has been no need to supply a gas fireplace with electricity because it has a standalone ignition system.

Although it can generate electricity, the heat generated from the fireplace is only minimal. Nowadays, there are modern gas fireplaces that need electricity to start the ignition. Electricity generates a spark to start the pilot flame.

However, there can be unexpected power outages during periods of cold weather, and it can be a hassle to try and heat your home. As a result, gas fireplaces now have battery backups in case the  electricity goes out .

You should only use the battery backup during a power outage. You cannot use the battery pack continuously as a power source, because it has a short lifespan. 

Types Of Pilot Ignition Systems For Gas Fireplaces

Before you use the batteries, you should first identify the ignition system of your gas fireplace. There are two types of ignition systems. Each type differs in its requirements for a battery backup. Keep reading to learn about the two types.

1.   Standing Pilot Ignition

If the gas fireplace has this system, it will not need electricity. It can generate light from the thermopile/thermocouple. This type of system has no connections with the home electrical system. So if there are power outages, you will have continuous heat from the fireplace. 

There can be times you need to light the pilot flame manually. You should connect the fireplace with batteries if you have trouble starting the ignition.  

2. Intermittent Pilot Ignition (IPI)

This ignition system requires electricity to create a spark every time you use it. It only lights up the pilot flame when you need it. The fireplace connects with the home electrical system to get its power supply. 

How To Use A Gas Fireplace With A Battery Pack


After you determine what type of ignition system your fireplace has, you can proceed to use the battery backup. You should check the product manual to know what type of batteries you need to use. You should access the battery tray first to insert the batteries. Follow the steps below.

  2. Find the location of the battery tray, which is normally underneath the furnace. When pulling the tray out, be careful not to tug the wires out. 
  3. Insert the required batteries into the tray.
  4. Then, return the battery tray. You will hear a beep indicating that the fireplace is ready to use.
  5. Return the access panel and close the furnace door.

The type of battery required will depend on the fireplace model and manufacturer. You should refer to the product manual for the unit's specific battery needs. 

Most battery backups require four AA batteries. Others will require six AA or two D-cell batteries. Buy high-quality batteries from trusted brands to provide the necessary power for the fireplace. 

How Long Do Batteries Last In A Gas Fireplace

With regular use, the batteries will last around six months to one year. It depends on how long you use the batteries when there is no electricity. Creating a bigger and prolonged flame also reduces the life of the batteries. 

You should remove the batteries once the power is restored in order to prolong their life. If the batteries do not work, you should replace them often. You should can change them once a year. In addition, remove the batteries during the warmer months to extend their life.
