Gas logs

Vented gas logs are intended to be used within a gas powered fireplace in which the damper will be opened. This is the most popular option of gas log available due to its ability to provide the most realistic look of fire wood.

Homeowners will find that vented gas logs can be purchased in a variety of styles and sizes. It is possible to purchase vented gas logs in a hickory, birch, oak or other popular fire wood design. This type of gas log is available in lengths that range from 12 inches to more than 60 inches to fit any fireplace installed within their home.

On average, vented gas logs cost between 60 cents to $1.75 per hour to operate depending on the type of gas used to power the fireplace. Unfortunately with the need of the damper to be opened when operating a vented gas burner, a large portion of the heat given off by the fireplace is not returned to the home and is instead lost up the chimney.

Regardless of the type of gas log a person chooses to use, there are safety concerns that should be addressed prior to purchasing them. One common misconception is the thought that homeowners do not have to conduct chimney cleaning when using gas logs. This is a practice that still must be completed. Gases burned can still build soot within the fireplace. Nesting birds and other debris that collects within the chimney can block the passage and catch on fire.

Those who choose to use unvented gas logs and keep their damper closed may find that gases can escape into the home. These gases have the ability to cause people inside to suffer from asthma attacks, allergies and other medical conditions in which they can become sensitive to the odors and fumes. This should be corrected immediately by limiting the amount of time a gas operated fireplace is used at any given period of time. 

Gas operated fireplaces also have a tendency to burn much hotter than a wood log fireplace. The surround areas around the fireplace should always be kept clean of items that can burn, melt or otherwise become damaged by the heat. Grating should be used as well to prevent individuals from being injured due to touching surrounding surfaces in which the heat is transferred to.
