Can I use a Chimney Pillow in a gas log fireplace? Does it matter what kind of fuel is used?
You can use a Chimney Balloon in any kind of fireplace or stove that you can reach into the chimney area above the damper. It does not matter what type of fuel is burned in the fireplace or stove. The Chimney Balloon material is resilient to your dormant chimneys environment. However, some states have codes about damper use with vented gas log fireplaces. I would encourage you to see the Fuel code for your state before using any type of damper with your gas log fireplace.
