Product Details:

316Ti Stainless steel pre-insulated chimney liners are used with fuel types such as wood, pellet, non-condensing gas, oil, and coal. Pre-Insulated chimney liner kits in stock typically ship within 1-5 business days.

Each Pre-Insulated Chimney Liner Kit Includes:

  • 316Ti Inner Stainless Steel Pre-Insulated Chimney Liner - Air and water tight, manufactured with the highest quality 316Ti stainless steel inner lining. .005" thickness. Made in the United States. Used for fuel applications such as wood, pellet, oil, non-condensing gas, and coal. Please add 1.25” to the liner size for the outside diameter (Ex: The 6” liner has a 7.25” Outer Diameter). Weight is approx. 2-3 lb./ft.
  • Stainless Steel Outer Liner - The purpose of the outer lining is to protect the insulation and keep it intact during installation. The 430 stainless steel outer lining isn't directly in contact with the emissions and by-products like the inner lining is. By using 430 stainless steel outer lining, you will not find a Pre-Insulated flue liner as economical and affordable as ours, without compromising on quality.
  • Rain Cap - Quick connect round top cap with a screen enclosure to keep critters and debris out. The rain cap easily attaches to the top plate with our quick connect band clamp system allowing for easy installation and future cleaning and inspections. Simply make your choice using the drop down window in Step 4.
  • Connectors - Choose between the two-part Tee Connector or the Vertical Appliance Connector.
    • Quick connecting tee with a removable horizontal snout for easy installation through your chimney thimble. If you're connecting or exiting the chimney horizontally you will most likely need the tee and tee clean out. Watch our Tee Connector installation video here.
    • Or, a quick connecting liner to stove vertical appliance connector. If you're connecting vertically to the top of your appliance you will most likely need the liner to stove connector.
    • If you have a pellet stove and need a 3" to 4" tee simply choose it in the options above.
    • Trimming back the insulation and outer liner is required when connecting the liner to your connector. Simply make your choice using the drop down window in Step 2.
  • Top Plate - Choose Between the Premium or Flat top plate featuring the quick connect system to easily install on your clay tile or chimney crown. Or a perfect fitting Quick Connect Terra-Cotta Top Plate that pressure fits with screws to the outside of the clay flue tile that protrudes from the chimney crown. Looking for an all in one top plate and rain cap? Choose between the Deluxe Terra-Cotta Top Plate with Hinged Rain Cap or the Deluxe Flat Top Plate with Hinged Rain Cap. The Deluxe models attach just as the standard top plate and are equipped with a hinged rain cap for easy access when you need to service the liner. Simply make your choice using the drop down window in Step 3. Watch our Top Plate & Chimney Cap overview video here.
  • Complete installation instructions - DIY stainless steel metal chimney liners installed the easy way! Most installations will take no more than 2 to 3 hrs. No rivets or clamps required.
  • Support - Free toll free phone support from Certified Technicians.

We offer the best protection for you and your home. Air and water tight chimney liners that lock moisture and flue gases in the flexible flue liner which keeps them from leaking into the home.

Guards Against Corrosion - Stainless steel chimney liners protect against hostile acids which deteriorate masonry clay tile chimneys.

What About Creosote? - Rockford chimney flue liners do not allow creosote to leach through the liner unlike masonry, clay tile flues, or liners not made of prime stainless. Creosote can catch fire, thanks to our Pre-Insulated Chimney Liners, this harmful creosote is minimized. Keep in mind, it is important to clean and inspect your chimney flue at least annually!

Seals Off Carbon Monoxide - When it comes to safety our flexible chimney liners will protect the structure of your home from moisture damage and the very real potential of carbon monoxide poisoning.

No Issues

Arrived well packed on a large pallet via common carrier. Instructions were missing from the box but otherwise a solid set. Can't wait for the Winter now! Watch your fingers on those taped ends people, razor sharp.

Great product

First things first. I reached out to Rockford to help me get the right product for my specific application and I can't say enough about how great they were in helping with everything. My order shipped quicker than expected and installed exactly as expected. Great product, great support. I can now have a safe warm home with my wood stove insert. Thanks Rockford.

Kit does what it does - but awesome support

The kit does what it says it will do. Everything appears quality, fit is perfect (Rockford's adapter fits into my woodstove better than the factory-provided one), shipping is free. But the thing that's really awesome is the support. I must have called 5 different times with different questions along the way and always got to talk to someone who knew what they were talking about within a few phone rings. The internet is great, but you can't trust 95% of it. It's awesome to have someone real to talk to. I would go with Rockford again 10 times over (though hopefully this is the one and only time I have to). :)
