Will fiberglass insulation burn?

Does anyone know how hot fiberglass insulation has to get before it burns? I want to put fiberglass insulation on the back of my wood/coal hot water boiler in my garage. There is a water chamber on the back of my boiler that is exposed to the cold and my water temp stays low in very cold weather. There is a flue and a cast iron water chamber on the back of this boiler, no open flame. I don't know how much heat fiberglass will take, any ideas?

There is always a concern when products are attached to or near the vicinity of open flames. The product mentioned above is one such product. There are also a variety of other products and manufacturers you can search for. I strongly recommend using a fire rated material in this application.
