Wind Noise in a Gas Log Fireplace

Gas Log Fireplaces

• Gas log inserts in fireplaces convert a traditional masonry fireplace into one that uses gas. They are also for use in gas fireplaces. The advantage of these systems is their realistic look. From across the room, a gas log fireplace closely resembles a wood-burning fire, but a gas log fireplace lights faster, sometimes with a remote.

Types of Gas Log Fireplaces

• Gas log fireplaces give you two options. Direct vent models use an exhaust to vent the fire, and have an efficiency of 65 to 75 percent. Vent-free fireplaces are up to 97 percent efficient, but you cannot use a vent-free fireplace insert in every room. Vent-free models use air in the room to fuel the fire and, in small rooms, they can use up all the available oxygen, creating a dangerous situation for people in the room. Only use vent-free gas log fireplaces in large rooms or with a window slightly opened to let a continuous supply of oxygen in the room.

Blower Fan Noise from Gas Logs

• Some gas logs are a part of a fireplace insert or gas fireplace equipped with a blower fan. These fans will make a whooshing sound like the wind when they are on. This sound is normal and it means that the fireplace is circulating heat throughout your room. Look for a fireplace model with a quiet blower fan on it to remedy this problem.

High Winds

• If you have a gas log fireplace that uses a metal flue to vent it from the side of your home, you have a direct vent model. In extremely windy conditions, wind can rush down the air intake for these direct vent fireplaces and blow out the fire or pilot light. As wind flows down a metal pipe, it can make the sound of a rushing wind. Check that you have a code-approved wind cap over the exhaust portion of the flue for your gas log fireplace. This will prevent large gusts of wind from coming down the flue, making noise and extinguishing your burning gas logs.
