While these aren't necessary if you follow the instructions above, there is a way to work fireproof gloves into the process. If you have a newer unit, it should come with some flexible tubing that can be attached to your new chimney liner and then routed through the house and outside. Some of these tubes are made from metal while others might not be. These will conduct heat and could potentially cause severe burns if they are not protected. The gloves are used to protect your hands while you adjust the flexible sections of tubing so that they can be routed through walls or ceilings without causing damage.
