Gas log fireplaces, or gas logs for short, are fireplaces that use gas instead of traditional fuel such as wood for lighting the furnace. In using liquid propane or other such natural gases, gas logs are less clumsy and give the fireplace an appealing appearance. They are of two types: vented and unvented logs. Of these, vented logs, which require the chimney damper to be kept open during use, are more popular. Ventless logs don't need the chimney damper to be lifted or opened during use.


Gas logs are built in such a manner that they don't require too much care. Most of the care is required during the winter months, when the fireplace is used more often. You can determine whether the log needs cleaning when there is a reddish flame instead of the usual blue. Furthermore, because gas logs do not use traditional wood, cleaning is simpler than with standard fireplaces.


Use a brush with tender bristles to clean the logs. You can also use a feather duster. Wipe the logs lightly, in the same way you would sweep the floor or dust any other surface. Do not clean the logs until after the main heat source is switched off and the fireplace has cooled down completely. If possible, you should begin by taking units that need cleaning, such as the logs and burner outside, before brushing so you don't get dirt elsewhere in your home.

Fireplace Cleaning

If you need to do a more thorough cleaning, turn the pilot light off and take the pilot nozzle out to clean it. Use a soft cloth to wipe the nozzle clean. Do not scrub it, just wipe it. After it is cleaned, before returning it, clean the heating unit by dusting it off either manually or with a vacuum cleaner. Return the pilot nozzle and clean the glass front of the fireplace using a cleaning agent–such as a mild detergent. Remember not to use any ammonia-based chemicals, as these can damage the glass. It is important not to use water, chemicals or cleaning liquids for cleaning the log. This can damage the system and cause it to stop working.
