Step-by-Step Instructions

1. Choose a Location

The first step is to choose a location for your fireplace. The location should be away from trees and other flammable objects. It should also be on a flat surface and have good drainage.

2. Prepare the Foundation

Once you have chosen a location, you will need to prepare the foundation. This involves digging a hole that is at least 12 inches deep and 24 inches wide. The hole should be filled with concrete and leveled.

3. Build the Base

The next step is to build the base of the fireplace. This is done by laying down a row of cinder blocks around the perimeter of the foundation. The cinder blocks should be mortared together.

4. Build the Walls

Once the base is complete, you can begin building the walls of the fireplace. The walls are built by stacking cinder blocks on top of each other and mortaring them together. The walls should be built to a height of at least 36 inches.

5. Install the Firebox

The next step is to install the firebox. The firebox is the area where the fire will burn. It is typically made of firebricks and is placed inside the fireplace opening.

6. Build the Chimney

Once the firebox is installed, you can begin building the chimney. The chimney is built by stacking cinder blocks on top of each other and mortaring them together. The chimney should be at least 3 feet tall and extend above the roofline.

7. Install the Chimney Cap

The final step is to install the chimney cap. The chimney cap helps to keep rain and snow out of the chimney and prevents sparks from escaping.

8. Enjoy Your New Fireplace

Once the fireplace is complete, you can enjoy it with your family and friends. Be sure to follow all safety precautions when using the fireplace, such as never leaving a fire unattended and always using a fire screen.
