The heat from the newspapers will be strong enough to push out the heavy cold air and establish a draft. Once you have made a couple of these “torches,” light them and hold them high up in the flue area. This newspaper will serve as a sort of “torch” that you will use to warm the flue.

Before you do so though, take a piece of newspaper (preferably paper without color or gloss) and roll it up. Once you are certain of this, get set up to start your fire. The first step is to make sure that your damper is all the way open. Instead, you want to warm up the flue first to push the heavy cold air out and start a draft cycle that will pull the smoke up and out of the chimney. The smoke will just take the path of least resistance and escape into your home. If you were to just light your fire without preheating the flue, the initial heat and smoke of the fire would be too weak to push the cold air out. This cold air is very heavy and essentially acts as a plug in your chimney.

When you are not operating your fireplace, the chimney is full of cold air (especially during the cold and damp winter months). Preheating your flue every time you light a fire is crucial to ensuring that air is cycling properly in your chimney system. We want to talk more in-depth about this preparation process to help ensure that you have a safe and pleasant fireplace fire experience. Prepping your flue is crucial to establishing a good draft in your chimney system. In our previous blog on “How to Get a Good Fire Going”, we touched on the importance of prepping your flue before starting your fire. Or rather, you can, but that fire will probably be quite smoky and difficult to sustain - and no one wants that.

Top tip: You can’t have a fire with a cold flue.
