Installing wood burning fireplace inserts can be a great way to increase the efficiency of your fireplace. You will be able to generate more heat for the room and cover up the front of the fireplace as well. The job of installing a wood burning fireplace insert is not complicated, but it will take a little bit of work and some knowledge on your part. Here are the basics of how to install a wood burning fireplace insert.

Step 1 - Measuring

One of the most important parts of the process is measuring correctly before you get started. Before you purchase your wood burning fireplace insert, you need to make sure that you have the right size. Take your tape measure and use it to measure the fireplace opening. Get the exact dimensions so that you can order the appropriate size.

Step 2 - Put the Insert in Place

You need to start up the process by putting down some cardboard on top of the hearth area. By doing this, you will be able to protect the tile or other material of the hearth. The insert can be heavy and bulky and you do not want to scratch the tile while installing. Place the insert on top of the cardboard and then slide it back into the opening. Get it back as far as it will go into the fireplace.

Step 3 - Flue Liner

At this point, you need to install a flue liner in the chimney. Get up on the roof with your ladder and take the liner with you. Take the chimney cap off and then start running the flue liner down through the chimney. Once you get the flue down through the chimney and to the insert, you need to attach it to the adapter on the top side of the insert. You should be able to use a screwdriver and screws to attach the liner to the insert. Once you have it in the chimney and attached, you will most likely need to trim off the excess liner on the top of the chimney. Use snips for this process and then discard the excess.

Step 4 - Mark the Opening

Take some chalk and use it to mark the front of the fireplace exactly even with the top of the insert. Then slide the insert out towards the front a little bit so that you can access the holes on the front and top.

Step 5 - Install Panels

You will now need to install panels on the front of the insert so that it will cover up the opening to the fireplace. With the top panel, you should be able to line it up exactly with the chalk line and barely cover it up. Use the screws and screwdriver to attach all of the front panels.

Step 6 - Finishing Up

You now need to install insulation strips on the back of the panels and caulk around all of the edges. Push the insert back into the opening and you should be finished.
