Installing a chimney liner is a daunting yet necessary task for proper maintenance of your home’s chimney system. To ensure the process is done correctly, it is important to properly prepare. First, you need to measure your chimney’s width and length in order to purchase the correct size liner. Additionally, you will want to check if the liner is manufactured from the type of material that is suitable for your type of chimney. Once you have these things determined, you can begin the installation process.

How to install a chimney liner

Before you begin with the installation process, it is important to ensure that you have all the necessary materials for the job. The type of chimney liner that you are installing will determine which items are required. Commonly, you will need a flexible or rigid stainless steel liner, a flue top connector, thread seal tape, and locking band clamps. It is also recommended to have a set of work gloves, pliers and safety glasses on hand to prevent any injuries while working. Once all your tools are gathered and ready to go, take one last moment to review your local building codes and regulations before proceeding with your project.

Measure the chimney

Before you can begin the installation of a chimney liner, you must first measure the chimney. The most important measurement is the internal diameter of your chimney, which will determine what size liner you need to purchase. This measurement should be made straight up from the point of exit at new or double skin flexible liner 4-7 inches above any internal obstructions such as clay pots, flaunching or parging and should not include any external brickwork (a few millimeters offset would be acceptable). For safety reasons, it is important that the measurements are accurate to ensure an effective fit.

Once you get an exact measurement of the internal diameter, you can then compare this with your chosen liners ‘nominal size’ (which may be slightly bigger than your measurement). For extra safety, we always recommend getting a liner that is slightly bigger than your measurements as over-sizing will not affect performance and too narrow a liner may not fit properly.

Purchase the appropriate liner size

Before you can begin to install your chimney liner, it is important to first purchase the correct size and type of liner for your chimney. It is critical that you measure the inside diameter of your flue before purchasing a liner as there are a number of size options available from 6-14 inches. A professional may be able to recommend the best type of liner for your needs after evaluating your chimney’s interior construction. Consider also any necessary accessories such as a top plate, top insulation, termination cap and thimble which can help ensure your installation is safe and code compliant.

Installation

Installing a chimney liner is a job that requires the utmost attention and caution. It involves connecting the liner to the chimney, and making sure that the liner is sealed in properly. The installation process involves a variety of tools and materials, and it is important to follow the instructions provided by the manufacturer. This article will discuss the different steps and tips necessary for installing a chimney liner correctly.

Install the top plate

The first step in installing a chimney liner is to install the top plate, which serves as a watertight seal. To ensure proper installation, it’s important to take your time and measure accurately. Start by measuring the diameter of the flue with a tape measure and then cut the top plate accordingly so that it fits snugly around the flue. It’s best to use sheet metal cutters for this task to ensure smooth edges on your narrow cuts and thus creating an effective watertight seal.

Next you’ll need to mount the top plate onto the roof using wide faced roofing nails, which should be spaced about 1 – 2 inches apart from each other along both sides of the top plate. In order to make alignment easier while you’re nailing in these nails, it may help to pre-mark their locations first by lightly tapping them into place with a hammer before attaching them securely into place with a nail gun or drill.

Once you’ve properly installed and secured the top plate into place, attach any necessary flashing or components that were included in your liner kit (e.g. bird guard, rain cap). Be sure to read through all manufacturer instructions carefully prior to installation as there may be additional steps required for certain types of chimney liners such as clay tile liners or insulated metal liners. Finally use caulk or mastic around any joints where pieces have been connected together in order for an adequate watertight seal before putting up your ladder and moving on to installing sections of your chimney liner!

Install the rain cap

The next step in how to install a chimney liner is to install the rain cap. The rain cap protects the chimney from water entering it. It should be made of stainless steel and installed at the top of your chimney. Depending on your roof type, you may need either a flat roof or an angled roof mounting kit, both of which are readily available. The kit should include appropriate flashing for waterproofing and gasketing for a tight seal. Once the cap is in place, secure it with appropriate masonry screws around its circumference to ensure proper attachment and air flow into the flue and not out the sides of the cap.

Connect the liner to the chimney

Connecting the liner to the chimney is a critical part of the installation process. It needs to be done correctly and safely, so it is important to follow all instructions exactly as specified. When installing a new chimney liner, you’ll need the right materials and tools, such as:

-Chimney crown sealant

-Silicone sealant

-Caulking gun

-Screwdriver

-Fireproof gloves/protective eye wear/long sleeve shirt

To begin connecting the liner to the chimney, you must start by measuring the interior width of your current chimney. Measure from the inside surface of one side of the inner flue tile wall to the other side and multiply this dimension by 2. This measurement, plus 1 inch on each side, is what you need for your new liner’s overall width. You will then cut an appropriate length tubing section of stainless steel (depending on your chimney’s size).

Once you have measured and cut your stainless steel LINER tubing section appropriately, secure it according to manufacturer’s instructions with brackets (or additional supports if requested). Now secure both ends of your new liner with silicone sealant or fire cement after confirming its fitment into position. Make sure all connections are tight and secure at both ends. Next use reinforced HVAC tape – or another type approved by local building codes – around each end connection at least two times around for extra safety and stability. Finally apply crown sealant around the top edge meshing vent to make sure there are no gaps between vent and masonry vents structures where heat may escape or rainwater can enter into house.

Finishing Touches

Now that the chimney liner has been installed, there are just a few finishing touches needed to complete the job. It is important to pay attention to the details when connecting the liner to the chimney – ensuring a water tight seal and the correct fit. In this section we will look at the steps needed to ensure that the liner will be securely attached to the chimney in order to prevent any water or debris from entering your home.

Secure the liner with screws

Securing the liner with screws is an important step in ensuring that your chimney and home are safe. Begin by inserting screws through the top plate into the liner. The amount of screws needed will depend on the length of your liner, but most installations need four screws per section. Make sure to use appropriate self-tapping screws to ensure a secure fit. If you’re using an aluminum liner, make sure not to over-tighten the screws, as this could cause damage to the material.

Repeat this process for each section of the chimney, securing one end and then moving up until it is fully connected. Once all sections are in place, connect them all with a stainless steel band at least 7” wide and 0.015” thick or thicker for extra security if required. Wrap it around every joint twice before tightening down with two self-tapping sheet metal screws on each side of every band joint connection.

Finally, test that the connection is secure by shaking each joint lightly with both hands or attempting flexing or stretching near any joints before fastening down for good measure. This can help detect if there are any loose spotted connections that need further securing or repair which might otherwise go unnoticed until much later on down the line and cause issues during future inspections or operation of your chimney appliance/fireplace system!

Seal the joints with high-temperature silicone

Once the liner is securely connected to the chimney, most installations require sealing the joints with high-temperature silicone, to completely protect against any gas escaping into your home. The silicone should be applied in a zig-zag pattern all around each joint, and then it should be left to dry for 24 hours. Once the silicone is dry, check the joints and ensure that there are no gaps that could allow any gasses to escape. With a properly installed chimney liner, sealed with high-temperature silicone sealant, you can rest easy knowing that your family’s health and safety are protected from potentially dangerous gasses and carbon monoxide buildup.

Test the seal with a smoke test

After the chimney liner is installed, you will need to test the seal to make sure the liner is properly venting smoke and other combustible gasses. This step may be optional based on local regulations and codes, but it’s a good idea to do it anyway.

To do a smoke test, you need to partially close off your appliance. Fill up a pot or bucket with wood shavings and light them on fire (use caution and follow all safety precautions). Place this inside the appliance near the venting connection.

Leave your appliance partially closed off long enough for any smoke generated to travel up through the flue, through the chimney liner, and out into the atmosphere. If there are any gaps in your seal as well-fitting joints, or cracks in brick or mortar- they will become apparent when smoke billows into parts of your home instead of traveling up through the chimney liner or escaping out of joints between bricks. This indicates that you will need to re-check all of your connections, use additional seals around your vents, check for missing sealant pieces at flue tile joints, replace any damaged parts along with connectors etc., before using this appliance again for its intended purpose.
