Tips for Your Chimney Liner
Your chimney is critical to the proper operation of your fireplace or wood-burning stove. Many people are astonished to learn that badly maintained flues and chimneys are a leading cause of home fires. There are several aspects that go into keeping your house safe when it comes to your wood or gas-burning appliances, including the chimney liner.
Apply Insulation and Flatten the Liner
Flatten the liner on a flat surface, then attach the bottom connection to the liner’s bottom and tighten a hose clamp to the connector using a wrench. Next, decide whether you’ll use an insulation blanket or pour-in insulation; a blanket is preferable if the gap between the liner and the chimney is 2″ or more. If you decide to go through with a blanket, measure the diameter of the bottom termination, multiply by 3.14, and then add 1″ of overage – now cut the blanket to meet this formula. Lay the insulation, the blanket, flat on the ground with the foiling facing down, then center the liner on it and wrap the insulation around it. Make careful to provide at least a 1″ overlap to secure with tape.
Spray adhesive, foil tape, and a hose clamp are recommended.
Apply spray glue to the liner, moving up in 12″ pieces, then seal the seams with foil tape. Continue wrapping the liner until it is entirely wrapped. One long length of foil tape is used to seal the long vertical seam. Cover the whole liner with the wire mesh that included with your kit (including the bottom connector). Use a hose clamp to attach the mesh at the bottom connector, then pull the mesh taut at the top and fasten it with another hose clamp; use snips to remove any surplus mesh that extends past this.
Get in the Boat and Attach the Rope
Do a short study of how to draw your individual liner down the chimney at this stage; this may vary based on manufacturer/brand, so familiarize yourself with the instructions. Attach the rope to the pulling cone or bottom connection that included with your package (depending on what specific liner you have purchased). Get on the roof near the chimney and have someone else help you feed the liner up to you – they’ll need to position themselves towards the bottom of the chimney on the inside. Toss the rope down the chimney and hand it to your partner.
Place the Bottom Connector
Next, place the bottom connection in the chimney cavity and carefully guide it down as your companion leads from below with the rope – avoid any snares or snags. Once the bottom connector has reached the required height for your chimney, you may use snips to remove the extra at the top, leaving 4″ past the chimney crown.
Chimney Crown Seal
Allow your partner to center the liner before sealing the chimney crown with silicone caulking – lay the top plate over the liner and press it down into the caulking to make a good seal. Tighten the fast connect clamp around the liner, using tap con screws in the drilled holes.
Connect the Connector to the Liner and the Tee Snout.
Attach the appliance connector to the liner and the bottom termination point now. Find the tee snout on the bottom of the liner and make a hole in the mesh and insulation where it will join to the tee body with your snips.
Connect the tee snout and the tee body using the pre-attached metal and wrap it around to the rear of the tee body; conceal the connection with leftover insulation. Finally, attach the tee snout to the heating appliance and you’re done!
