Learn About 304L Rigid Chimney Liners

No more lock form seams, or spot welds that are leaky and dangerous enough to be illegal in Europe! One of the great features about our rigid chimney liners is the seam and how it keeps the pipe perfectly round. Lock and spot welded seams warp, ours will not. Our seams are laser welded, leaving virtually no seam to be seen. Our stainless steel flue pipe sections slide together for a tight fit, the first time, every time (use our rivets for an easy install & tight fit!).

Use 304L stainless steel rigid flue pipe for wood or wood pellet burning appliances. Best used for straight chimneys without any offsets. You are able to extend the pipe above the chimney top for added height. Our rigid flue pipe is easy to clean, heavy duty, and increases your draft due to it's smooth interior. If you have offsets or a very tall chimney, our stainless steel Rock-Flex liner is a great alternative. If you are burning pellets, gas, oil, or want a greater corrosion resistant liner, the 316L stainless steel rigid liner is also available.

What Parts Do I Need?

The diagram at left shows the parts typically needed at the top of the chimney. The rigid liner(1) is inserted into the chimney. The chimney top is covered by the top plate(2) which goes on over the liner. Support clamp(3) holds the liner in place and keeps it from slipping down the chimney. The storm collar(4) covers the gap between the liner and top plate to keep out moisture. The rain cap (5) gives an attractive finished look while keeping rain, birds and critters from getting into your chimney, and sparks from getting out.

Connecting to Your Appliance

Fireplace Connection:

If you are connecting to an existing fireplace without an insert, you will need an additional top plate to use where the bottom of the liner reaches the fireplace opening. You may also need to fill the space around the liner with insulation mix.

Insert:

If your fireplace has an insert with a top opening, you may need an elbow connector.

Stove/furnace (or other appliance needing a horizontal connection):

You will need a rigid tee connector with removable snout and clean-out cap.

You may also need:

Rigid adjustable elbows to change the angle of the liner, and pop rivets for assembly.
