Applications: Wood and wood pellet burning appliances

Click here to view typical components for rigid lining kits.

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.

No more struggling to force one pipe into the next. These ends slide together for a tight fit, the first time, every time.

What Parts Do I Need?

304L Rigid Liner Top Assembly

rigid liner top assembly

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. A 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.
