FAQ: Vented and Vent-Free Gas Logs

If you have a question about gas logs, here is an FAQ all about gas logs. It gives basic info, and quick answers to questions frequently asked about these alternative fire sources.

Can I Install Gas Logs Myself?

If you are a professional who has knowledge of gas fireplaces, fireplaces in general, HVAC systems, and or plumbing experience, then yes you can definitely install gas logs on your own. If you do not, (No!) then it is highly recommended that you do not, and leave the installation up to an experienced professional for safety and accuracy reasons. A qualified specialist will also have all the necessary tools to safely install the logs, and guarantee that everything follows the according code.

Are Gas Logs Meant to be Used in Specific Sizes?

Yes, they definitely are. When purchasing gas logs, you will see that they are sold in sizes, and you will be given directions for measuring your fireplace. It is highly important to have the proper space around your logs, and a proper distance to the wall so that you avoid causing fires and explosions due to overheating.

Can I Use Vent-Free Gas Logs in a Vented Fireplace?

No. Both types of logs are meant to be used in their appropriate housings, and should not be mixed and alternated. Because they are specifically designed to work in ventless or vented fireplaces, those are the only ways they should be used. As with any product that involves fire, and can create a potentially dangerous environment, all manufacturer directions and warnings should be followed explicitly.

Are Gas Logs Legally Allowed Throughout the US?

In most states, counties and cities, yes. However, several states such as Wisconsin, Montana, and California (this is a no-brainer) do not allow the use of unvented gas logs. New York City also does not permit their use. Gas logs for the vented fireplace are more tolerable. Before you purchase, and make the investment in gas logs, be sure to examine the local codes and laws in your area regarding their use.

Can I Use My Gas Log Burner to Burn Wood?

No! Absolutely not! It can cause damage, and destroy the burner. If your burner gets damaged during such use, your warranty will most likely be dissolved, and will not cover it. Gas log burners have been created to burn only gas logs, and no type of organic matter.

Is my Coal-Burning Fireplace Able to Burn Gas Logs?

No. A coal-burning fireplace is meant to burn coal, and nothing else. It may be possible though, to convert the firebox into one that can tolerate gas logs.

Do Gas Logs Create Unsafe Breathing Conditions By Emitting Gas Into the Air?

It is possible, but generally, no. They are sold with oxygen depletion sensors, and, monitoring devices that keep the gas in check. Should you suspect a gas leak, call your local fire department immediately, and turn on no electrical switches.

When Gas Logs Are Lit, Are Their Embers Flammable?

No, they aren’t. They are simulated, and do not really burn. While they are beautiful, and do look like the real thing, they are really fireproof, and add to realistic design of gas log fireplaces.

Which is Better: Propane or Natural Gas?

One is not better than the other, however, with propane it is always necessary to have a safety pilot. The safety pilot is entirely essential because it ensures that gas does not accumulate within the house, which can create a disaster should someone accidentally turn the gas line on and not turn on the fire. Natural gas is a bit more flexible, as it is lighter than air. If you have a vented fireplace, natural gas is fine because you have the ability to keep the damper open continuously. Natural gas also works best in homes where there is a natural gas hookup for the entire house.
