Henriette Firepit February 23rd, 2018 - 11:01:43
Buying a new copper firepit can be a great addition to any deck or backyard. Copper is a beautiful metal, and its long lasting and durable. Copper wont rust or corrode, unlike other metals, so your firepit will last for years and still look as good as the day you bought it. Another nice thing about copper is that it also conducts heat very well, so you will have a warm fire while burning less wood. Purchasing a firepit that is made of copper can be a very smart thing to do. Once you bring home your new copper firepit, youre going to want to think about accessories. One thing that is a very good idea is to buy a screen to place on top. This will help prevent hot ashes and burning embers from leaving the pit. Some firepits come with a screen, others may not so if yours doesnt have one you will want to think about purchasing one. You might also want to consider purchasing a lid to help put the fire out quicker at the end of the night.
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.
Procedure: First, we excavated a pit approximately 1metre (3 feet) in diameter and 800mm deep. The ground we were working on was very rocky so we used a backhoe and it was difficult to carve a smooth hole as you can see by the photos. Next we dug a drainage channel from the bottom of the hole to a lower point beyond the extent of the fire area. This was essential in this circumstance due to the heavy rainfall and the heavy soil. If your soil is porous it may not be necessary to provide drainage to the pit. In the channel we laid the plastic drainage pipe and covered it with gravel. Because we wanted to line the pit with the 600mm granite slabs we placed extra gravel in the bottom of the pit to set the stones on upright in a circle.
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.
