A gas corner fireplace is very easy to install, with all of the right tools and materials available.You will be able to install a gas corner fireplace completely by yourself, with the exception of the gas line installation, which will need to be performed by a professional with experience.

Step 1 - Measurements

First, you need to measure the size of the corner you have available and decide on the type of fireplace that you want to install. Get an idea of how this will fit by making a rough model out of cardboard and tape. Creating a 3D model will make it simple to take a look at how the finished fireplace will actually look once it is finished and installed.

Step 2 - Choosing the Hearth

Most gas fires will require the use of a hearth for safety. Work out the size of the hearth and what materials you intend to use to make it. There are lots of different materials that are suitable for hearths, including granite, slate, stone and tiles.

Step 3 - Fitting the Hearth

The hearth will now need to be cut and fitted according to the type of material that you are using. Cut this accurately so that it is a snug fit. If there are any pipes coming up through the bottom of the fire you will need to drill or cut the hearth to allow these pipes through.

Step 4 - Securing the Fireplace

The corner fireplace needs to be placed on top of the hearth and secured down with bolts. These bolts will need to be drilled carefully into the hearth so that you don't cause any damage or risk cracking the hearth. The flexible gas pipes now need to be connected up to the fire by tightening the connection using an adjustable wrench.

Once the fireplace is installed the trim needs to be fitted to hide all of the fixings from view. Fix the apron onto the fire to complete it.

Step 5 - Fixing the Mantelpiece

The mantelpiece now needs to be fixed around the fire and secured by screwing into the studs in the wall.

Step 6 - Finishing the Wall

At the moment, the fireplace will be angled and positioned in the corner of the room. To make the corner fireplace look like a more integral part of the room the wall needs to be angled. Building a diagonal wall will make the fireplace look much more built-in. Fix battens on the wall and then cut a piece of plywood to the right shape. This can then be screwed over the corner to create the angled diagonal wall.

Joint compound now needs to be applied along the seam between the plywood and the wall. Joint tape can be used to prevent these cracks. The wall can then be finished to tie it into the rest of the room.
