How to Install Gas Logs

If you already have an established fireplace or firebox, installing a new set of gas logs is incredibly simple! In fact, you can have the gas line connected and the whole system running in just a few hours.

To help you install gas logs and have your gas fireplace roaring before you know it, you can use the following six steps:

Step 1: Prepare Your Fireplace or Firebox for Gas Log Installation

The first step is to ensure that your gas log set has a place to safely burn. If you have a home with an existing fireplace, you can often simply lead in the needed gas line and establish the gas log set in the pre-existing space. Some people prefer to brick up part of the fireplace to close out the flue and reduce the amount of space around the gas log set, which is an option to consider.

If you do not have a pre-existing fireplace, you will need to order a device like a firebox or fireplace insert, which is a prefabricated chamber usually covered by a glass door or a chain link curtain. You could also manufacture a fireplace box by hand, but it must comply with the expected BTUs and size clearance your intended gas log set will require.

One of the most important aspects of installing a new gas log set is having the required space clearance. Generally, every set will need 2” – 6” on either side, meaning the dimensions of the intended fireplace or firebox must be 4” – 12” wider than the intended set. Mantels must also meet minimum clearance, so review your product manual and local building codes to ensure safety and compliance.

Step 2: Establish the Needed Ventilation

Gas log sets come in two types: vented and unvented sets. Vented sets must have a metal vent system to exhaust the heat and fumes outside. Ventless or vent-free systems must have adequate airflow around the unit to safely operate.

Once again, consult your product manual and local building codes to ensure that your gas log set can operate safely. Note that some states, such as Minnesota, do not allow for the installation of vent-free gas log sets in homes.

Step 3: Connect the Gas Supply

Your supply of propane, liquid propane or natural gas must then be fed into your gas log set location. Gas line pressure must be regulated to the proper amount, usually 10.5” of water or less. A shutoff valve must also be installed to ensure the safe shutdown of a fire in both an emergency and when the system is not in use. Pressure of gas lines must be tested, and the entire assembly should be sprayed with a diluted soap substance to check for bubbles and leaks.

Step 4: Installation of Burner Element

Once gas lines have been safely fed into the burning site and tested, the gas fireplace apparatus can be installed. Follow the instructions of your manual to connect the assembly safely and securely. Valves and other safety systems should be tested for pressure and proper operation once more.

Step 5: Arranging of Simulated Logs

Once the burning element is securely connected, completing installation is as simple as arranging your simulated gas log set. Make sure to arrange the logs as indicated in the instructions to ensure proper, safe burning patterns and to avoid sooting or fumes.

Step 6: Follow the Steps for Safely Lighting Your Unit

After completing the assembly of your gas log unit, you can follow our instructions for lighting your gas log set for the first time.
