Its a bit tricky to get the heavy slabs in an exact circle with a consistent height but its best to prop them up and backfill with the gravel so that each stone is buried 150mm leaving a 450mm deep pit. The top of the granite should be 200mm above the surrounding ground level to allow for the concrete slab and paving. You could cut each stone lengthwise along one edge to make them fit flush with each other but it isnt necessary. The bottom of the pit was then paved to make shovelling out the ashes easier.
Another thing that you will want to consider after you have bought your new copper firepit is a grill or a grate. Check your instructions before purchasing a grate, if your firepit wasnt made for cooking then you wont want to buy a grate. It doesnt make any sense to take chance with something like fire. If your firepit is made for grilling, your instruction manual will tell you the right size grate for your particular model. There are a couple of other things that you might want to consider buying to also go with your copper firepit. If you bought a set it should come with tools for the fire, but if it didnt you will probably want to purchase tools. You will want something that you can use in the fire if you need to stir the wood. Another nice accessory is a cover. Copper can withstand the elements, but wet ashes can be very messy and a cover can save you that hassle. Finally, some people like to have a rug to place their new firepit on. If you decide that you want to use a rug, make sure it is fire resistant. You dont want to take any chances.
Once the stone lining was completed we used an excavator to place the large stone seats. Depending on the size of the stones they may have to be dug into the ground or set higher on gravel to give them an approximately consistent height. Bearing in mind that a comfortable adult seat height should be 300 - 400mm the stones need to conform to this measurement. By the time the concrete is poured and the paving laid the finished ground height will be 150mm higher than existing ground level, meaning that the rocks should stand 450 - 550mm above the ground.
Your first step is, of course, to choose where your firepit will go. Pick an area that doesnt present a fire hazard and that will be comfortable for you and your guests to sit and relax. If, for example, you know one part of your yard is prone to mosquitoes, you would certainly want to avoid that spot. Just think practically, and you should be fine! When youve decided on the size and location of your pit, mark it using chalk or paint. If there is sod in the area, youll need to remove it, and you should also use a pre-emergent herbicide in order to prevent grass from growing in that area again.
