By-products from the combustion process can cause the glass doors on your wood burning fireplace or stove to have a build-up of deposits, including creosote. This tends to build up in your chimney’s flue, which is dangerous and highly flammable. However, you can get round the problem by properly maintaining your fire.
Always burn dry and seasoned wood as this helps to minimize the build-up. Wet wood generates more creosote. Small, hot fires reduce creosote levels by thoroughly burning the wood. This also reduces the levels of smoke and gives off more heat, so it’s better all round. You can also open the air vents to minimize any deposits build-up.
