Fireplace Burners

If you have a gas fireplace, you are going to need to know how to replace the burner in the unit. These devices do wear out over time and need to be checked periodically for gas leaks and other defects. There are a number of burners available on the market, each of which has their own individual specifications. The main difference is between vented and vent-less burners; be sure to choose a model that will work with your unit. Here are some helpful tips for understanding the difference between them, as well as for how to replace the burner in your fireplace when the time comes.

Types of Fireplaces Burners

Vented burners produce realistic looking flames, but require a chimney or flue to operate
Vented burners cannot be installed in fireplaces that are not pre-equipped with a chimney or flue. This is because the logs that are placed in these fireplaces do not burn all of the gas cleanly, which results in toxic gas emissions that must have room to escape. Vented fireplace burners thus produce a much more realistic flame than their vent-less counterparts. Remember that this comes at the cost of heat; however, as most of it will be lost up the chimney/flue.

Vent-less burners do not need ventilation, which means they produce more outward heat
Vent-less burners are meant to be installed in fireplaces that do not require ventilation. The flame they produce may appear more artificial, but users get to experience all of the heat that is being emitted. You will want to make a note of the type of fireplace you have to ensure you are selecting the proper burner. This may seem obvious, but many homeowners fail to take into account these requirements.

How to Install Fireplace Burners

  • Attach the flex line adapter to the gas line
  • Install the flex line into the adapter; be sure to place the burner over the line
  • Adjust the burner to ensure proper placement
  • Light the burner and verify there are no gas leaks present

Installing a burner is not too difficult, but it does require patience to get right. Remember that you are dealing with toxic gas, so it is very important to take your time and do the job right. The first step is to attach the flex line adapter to the gas line. This is accomplished by screwing the adapter into place.

After you have installed the adapter, the next step is to attach the flex line. Make sure the burner is resting on top of the line. If it is not, you run the risk of the flames coming into contact with it, which is very dangerous.
