Is it Normal for My Gas Fireplace to Smell?

Benefits of a Gas Fireplace

• Gas fireplaces are a wise purchase for homeowners who dislike the messy cleanup that's involved in keeping a wood-burning fireplace tidy and safe. Installation of a direct-vent gas fireplace is quick work for a professional and these fireplaces work almost anywhere in your home because the exhaust gases only require a wall vent, not a standard fireplace chimney. Gas fireplaces are typically less costly than masonry fireplaces as well.

Odors With New Fireplace

• It is normal for new gas logs to emit an odor for approximately six hours when you first light it. Read the owner's manual to determine how long to expect the smell to last with your particular model. Operate the fireplace on a day when you can light it for the number of hours stated in the owner's manual. Some types of gas fireplaces have an optional fan. If yours does, turn it to the "Off" position during this initial burning time. Ventilate the room by opening all the windows to allow the smell to escape. The odor is a byproduct of the curing of the stove's paint and the burning of oils used in manufacturing the stove.

Debris on the Firebox

• Debris on the inside of your firebox can cause the gas fireplace to smell as well. A buildup of pet dander, dust, or cigarette or other tobacco smoke may cause the odor due to the residue settling inside the firebox. Other causes are aerosol sprays, air fresheners and the residue from burning incense or candles. If you have recently stained or painted inside your home, installed new carpets or other textiles or used glues or cements, this may also result in offensive odors when the gas logs are lit.

Cleaning the Gas Fireplace

• Clean the firebox if you suspect something inside it is causing the odors. Remove the louver from the top of the unit with a screwdriver. Inspect it for residue or a greasy or dusty film. Clean the area with the cleaning solution recommended by the owner's manual. Wiping out the firebox with a damp cleaning cloth and vacuuming the area regularly prevents odors from animal dander and other airborne particles. Over time, the pilot assembly and inlets become soiled, thus requiring a professional servicing and cleaning.
