A metal chimney pipe is a cheaper option than having a masonry chimney installed from scratch. The chimney pipe can handle all kinds of venting gases, including those which come from wood stoves, or even working fireplaces. The cost of installing a metal chimney pipe is not cheap, but it is much more cost effective, and less disruptive than having to have masonry installed in your home. If you wish, you can employ a professional to install the chimney pipe, and ensure that it is leak free, but if you would like to save a little bit of money, and you have some home improvement skills, then you should be able to install the pipe yourself by following a few basic rules.

Step 1 - Fitting the Bucket

Inside your metal chimney pipe kit, you will find a device known as the ceiling bucket. This will be wider and flatter than the rest of the pipes, and will need to be stalled from above the ceiling. Using your saw, cut a hole in the ceiling which is around the same size as the bucket. There should be two types of plate, the ceiling trim and the support trim. The latter will cover the ceiling hole. With a friend, lift the bucket up so that it is under the ceiling hole, and then one of you should go to the space above the ceiling, and screw the two plates together, so that they hold the bucket in place.

Step 2 - Fitting the Pipes

You can now fit pipes to the stove. They should come down until they are almost level with the stove outlet (cut off any excess length using your saw or a pipe cutter), and then attach to the back of the stove via a fitting pipe. This will have connection nuts on both sides, and will fit over the edge of the pipes, and then be connected to the outlet of the stove. Tighten until the pipes are firmly held.

Step 3 - Fitting to the Roof

Once the stove has been connected, you can carry on and install the pipes to the roof. These pipes need to be supported every 5 to 8-feet, using brackets to hold them to the wall. You will need to cut a hole in the roof to the approximate size of the pipe, and then add support plates on either side. The metal pipe should be around 3-feet above the level of the roof, from the hole to the top of the pipe. You can fit a vent cap by loosening the shingles or tiles around the hole, and sliding the cap underneath. If you do move the shingles, add roof mastic at the end to keep them in place.

Step 4 - Finishing Up

Once this is complete, you can then start protecting the pipe by caulking around any joins. Add caulk to the screws, and around the hole in the ceiling. You should also caulk against the inside of the roof, in order to ensure that your pipe remains firm.
