Gas Log Fireplace FAQ

What Types Are Available?

• There are two types of gas log fireplaces: a vented log fireplace and a ventless log fireplace. A vented log fireplace is not meant to heat a room, but instead provide flames that mimic a wood-burning fire without the hassle of lighting kindling. It must be run with the chimney's damper open. Logs are available that resemble hickory, oak, birch and other types of wood. This type of gas log fireplace can be run by a wall switch or remote control for added convenience.

  A ventless log fireplace provides blue flames that can help supplement a room's heating system. The logs used are not as decorative as those in a vented log fireplace, but they provide more heat and burn cleanly so the chimney's damper does not have to be open when the fire is lit. Closing the damper allows the heat to be concentrated in the room, but because these logs burn so hot, a hood must be placed over the fireplace opening to protect the mantel from the heat.

What Types of Gas Can Be Used?

• A gas log fireplace can use both natural gas and propane to fuel its flames. However, natural gas is usually a better option because it is cheaper and burns more cleanly than propane, and is thought to be safer as well. Because propane is heavier than air, it can form pockets in the lower portions of a room, which can become very dangerous. If you utilize natural gas for your fireplace, it is supplied through home lines by your local gas utility company. Propane is supplied by private companies and must be stored in tanks on your premises.

Can You Install One Yourself?

• Installing a gas log fireplace is not a project that you should attempt yourself. Have your fireplace installed by a qualified gas installer, such as a heating, ventilating and air conditioning professional or a plumber. In most jurisdictions, a permit is required for a gas log fireplace installation, and only the homeowner or a certified gas contractor can obtain one. In addition, a newly installed gas log fireplace must undergo an inspection to ensure that it is safe for use.

What Maintenance Is Necessary?

• A gas log fireplace should be inspected and cleaned on a yearly basis. The chimney should be checked as well to ensure that it is in proper working order. If you have a ventless gas log fireplace, annual maintenance is especially important, because dirty burners or orifices may cause the burners to develop soot. Since the fireplace is not vented, the soot may enter the room and give off deadly carbon monoxide.
