Build a chimney – Part 2

Build or add an exhaust for fireplaces. The chimney must be constructed to the exact specifications to ensure adequate smoke output from inside the combustion box. It must have a smoke blocker to prevent it from descending and a duct of optimum dimensions. The exhaust must also be at least half a meter (2 feet) higher than any adjacent structure.

Add spark arrestor. Like the exhaust, the spark suppressor is exclusive to wood-burning fireplaces. Catch the embers of the stove.

Install the home. The hearth is the protrusion at the opening of the chimney and perhaps the center point of the chimney outside. Installing it properly is an important part of building an outdoor fireplace.

Place mortar into 2 cm (3/4 inch) deep strips, 1 inch (2.5 cm) from each.

Install the home with a rubber mallet and level to make sure it is straight and level. If the home is not glued to the combustion box, no problem. This will make it harder for sparks to fly out of the box.

Select a stone style for the cladding. Apply mortar to the back of the stones and glue them onto the concrete blocks. Use spacers to separate the rocks, filling the area between them with mortar.

With perfect 90-degree corners, it avoids the continuous joints that extend throughout the chimney. Instead, make an asymmetrical surface. Place the first rock pressed into a corner and separate the next rock about 2 cm (1 inch) from the first. With the following two rocks, alternate the joint. Put the first stone separated and the second stone pressed to the wall. This creates an attractive alternating pattern that goes from the corners of the fireplace.

Once installed, allow the mortar to harden for at least 24 hours. If possible, give the fireplace several days of rest before using it.

Connects a gas fireplace to a gas line. If you build a gas fireplace, be prepared to connect it to a line.

Turn off the gas.

Use plumber’s putty in the main line connections to connect it to the flexible lines.

Adjust the connection with a wrench until the filler hardens. Test the connection by applying soap on it.

Turn on the gas. If bubbles appear, reinstall the connection.

You gave value to your home successfully and revitalized your backyard. Enjoy your new outdoor fireplace!
