Using the Biolite FirePit FireMat is a breeze. First, unroll the mat on the surface where you plan to place your FirePit, like your deck or lawn. Then, simply put your FirePit on top of it. When you're done using the FirePit, roll up the mat and store it away. As for precautions, make sure the mat is placed on a flat and stable surface. Don't use it near flammable materials. For maintenance, if it gets dirty, you can wipe it with a damp cloth. Keep it dry when storing to maintain its durability and waterproof quality.
