The clearance information is found on the labels attached to the pipe and in the manufacturer's installation instructions. The rules for their installation may differ from the rules for single-wall flue pipes.
A straight up double wall flue pipe assembly. This one is the sealed type. The minimum installation clearances for certified double-wall flue pipes are much less than those for single-wall pipes.
Also, the maximum length of a double-wall flue pipe assembly may be greater than is permitted for a single-wall pipe. There are two general types of double-wall flue pipes: sealed and vented. A sealed double-wall flue pipe is effective at retaining the heat in the flue gases because the air space between the inner liner and outer shell acts as an insulator. A sealed double-wall pipe is a good choice to maximize draft and minimize creosote deposits.
Use sealed double-wall pipes if the assembly must be long or if the appliance is expected to produce low flue gas temperatures. The system to the left uses a sealed double wall telescopic length between the stove and chimney.
A vented double-wall pipe allows cooling air to pass between the inner and outer layers. Where the flue pipe assembly is short and straight, a vented double-wall pipe can be acceptable. However, vented pipe is not a good choice for longer flue pipe assemblies or for appliances that are expected to produce low flue gas temperatures.
Nice Things Readers Say "You have a fantastic site. You must have JavaScript enabled in your browser to utilize the functionality of this website. First, you must determine the appropriate size chimney liner for your specific setup.
The chimney liner diameter size you will need is the same as the size of the exhaust hole on the appliance. The chimney liner length you will need will equal the height of the chimney. We recommend ordering slightly over that amount to give room for error. The flue liner legally needs to be a minimum of 6" in diameter if you are burning wood. Unless when you instal a DEFRA approved stove with a 5" flue outlet, in which case you can use a 5" liner.
Never go down in size along the flue road; as the bottleneck will cause smoke to back up. If you instal a chimney liner into an existing chimney, be sure to get the chimney cleaned first as this will ensure there is no residual soot or other obstructions that could create difficulties with the installation.
The arrow on the liner indicates the direction of the smoke. Install the liner with the arrow pointing upwards. This check ensures that all flue liners are properly installed; that they are the right size for the appliance requirements and that they are completely free of obstructions. Only a few tools are needed for a successful chimney liner installation. You'll need a utility knife, flat head screw driver, caulk gun, a pair of working gloves, a power drill and safety glasses.
A grinder will give you the best cut when cutting off the excess chimney liner. A saw or hacksaw will also work fine. You can install your chimney liner either from the top or bottom of the brick chimney stack. Whichever way you choose to install the liner, please ensure that you have sufficient clearance around the outside of the liner to ensure the least amount of friction, or possibility of catching any bricks within the chimney stack, does not occur.
Unpack your flexible liner and attach a rope at the lower end making sure the rope is long enough to reach the bottom of the stack. Ensure the arrows marked on the liner are facing an upward direction representing the direction of flue gases.
You will need two people to install your liner successfully, one at either end of the chimney stack. The person on the roof should be safely attached! The grinder will give you the best cut when cutting off the excess chimney liner.
A sawzall or hacksaw will also work fine. A power drill will also be needed for the project but is not shown in the picture. Every basic chimney liner kit is going to come with four main components: the stainless steel chimney liner, a two part tee, top plate, and rain cap.
This demonstration will show a basic installation, but a chimney liner kit can be customized to fit any particular chimney. The top plate is going to be the main variable for a chimney liner kit. The chimney liner will be rolled and needs to be straightened. Simply remove any wrapping or ties from the liner and lay it out on the ground to pull it straight.
When using home heating oil, natural or propane gas insulation is not required but we do recommend using it as it will reduce condensation. Simply follow the installation instructions included with the insulation kit or you can purchase the Forever Flex Pre-insulated chimney liner as shown here. You will be using a two part tee. The part of the tee connection with the cut out on the side is known as the tee body or vertical part of the tee.
The part of the tee with the looping hose clamp is known as the tee snout or horizontal part of the tee. Start by locating the vertical part of the tee and insert the liner into the top of the female end. Tighten the clamp at the top of the vertical part of the tee around the liner with your flat head screw driver. This will give you a great, tight fit without having to drill screws through the liner.
The first part of the chimney liner that will be going down the chimney is the vertical part of the tee connection attached to the liner. Proceed to lower the liner down the chimney until you reach the thimble. The thimble is referred to as the hole on the side of the chimney in the living space that allows stove pipe to attach to the chimney.
Twisting the flexible liner will help you install the liner if you are getting caught or hung up on the chimney walls. You should have someone located by the thimble in the living space ready to install the horizontal part of the tee. Locate the horizontal part of the tee connection. First, insert the horizontal section of the tee, hose clamp end first, into the thimble. Snake the vertical part of the tee through the horizontal hose clamp until the lips of the tee body are inside the horizontal part.
You will find when you look through the inside of the horizontal part of the tee that there is a worm screw. With your flat head screw driver, tighten the worm screw until the two parts of the tee connect. Take this step slowly.
