You don't have to worry about destroying anything; even don't have to take concentrate on fire maintenance. You can concentrate on forging, and don't worry about working a fire. This is another reason gas forges are excellent. Especially, at the time of winter, it puts out a lot of heat, and this really warms up this area of the shop or your house. It's even better than most furnaces. When it is cold outside, it is a delight to work around a propane forge in the winter. Eventually, you don't need to take care of it; rather, it will take care of you at a certain time of the year.
