How to Choose the Right Gas Logs

Switching from a traditional log system is one decision homeowners should consider. The use of gas logs is a safer, affordable, and clean alternative. They help you to save money, protect the natural environment, and improve the quality of your indoor air. This guide provides key points to consider when choosing gas logs.

1. The Venting Options

Generally, the venting system is divided into 2 categories: vent-free and vented. Each option has its benefits. If you’re choosing a gas log for an already existing fireplace, you need to be sure of the venting system in place. 

However, if you’re choosing products for your new fireplace, you need to consider what makes both options different.


  1. It supplies more heat within the property than the vented system.
  2. The installation must be done in an approved fireplace.
  3. The installation can be affected by local and state building codes (some locations do not permit homeowners to install a vent-free system).


  1. It is more realistic as the flame it produces appears more natural than the vent-free type.
  2. The installation must be done in a wooden fireplace that is fully functional.
  3. The heat goes up the chimney and reduces the amount that is circulated around the room, making it similar to wood logs.
  4. When the logs encounter flame, they produce some soot.

2. The Fuel Type

There are 2 fuel types: natural and propane gas. If the building already has connections to a gas line, your fuel source is natural gas. This is a popular option among homeowners.

You can also check your other appliances to see the fuel source they use. If your stove, dryer, heater, and other appliances use natural gas, then this will likely be the choice. On the other hand, if the building does not have a gas line, you can choose from any of the other fuel sources. You can also check what is acceptable within the locality. 

3. The Log Size

Your fireplace has dimensions, and this determines the log sets to buy. If you do not get the correct size, it can result in overheating as well as irreparable damage to the valves and firebox. Measure the height, depth, back width, and front width of the fireplace to get its dimension.

4. The Starting and Controlling System

There are 4 basic options: electronic ignition, variable valve, millivolt valve, and safety pilot.

Safety Pilot

This is like the type in a water heating system. Turning the control knob inside your fireplace lights the pilot. You can use this system without worrying about gas leaks in your home.

Millivolt Valve

This type uses a remote control to either turn the logs off or on. You can also have a standby pilot.

Variable Valve

It uses remote control that not only allows you to turn the logs off/on but also to control the height of the flame. 

Electronic Ignition

This type gives you full control over the logs. You can use a remote control to either turn the pilot off or on without touching its control knob. You can also turn the logs on/off and adjust the height of the flame. You can check to know how to start your fireplace.

5. The Accessories, Material, and Style

A gas log is made of ceramic fiber or refractory ceramic. The manufacturers use wood molds to design the logs to look like real wood. Refractory ceramic usually last longer than ceramic fiber. They do not disintegrate and produce a strange smell over time.

The type of log you choose depends on your taste and preference. Generally, if your preference is the flame’s appearance, choose a vented system. If heating is your priority, the vent-free system will be good for you. Also, you can choose premium brands that offer various flame options and crackling accessories.


Gas logs provide a clean heat source and are great alternatives to wooden logs. However, it is important to choose the set that best suits your fireplace. This will prevent overheating and damage to the entire system.
