Rigid Chimney Liners

Stainless steel rigid chimney pipe is offered in two stainless steel grades: 304L and 316L. 304L is used for wood burning applications. 316L is multi-fuel used for gas, oil, wood, corn, coal, and pellet, just to name a few. Both grades of stainless steel rigid pipe are 24 gauge. One end is expanded for better flow and easy pipe to pipe connection. All seams are laser welded, so gases and moisture stays inside and the pipes stays perfectly round. The interior of the pipe is smooth, giving you a 20% better draft for gas burning appliances and a 15% better draft for oil appliances. All stainless rigid pipes are UL listed in the US and Canada. These stainless pipes can be used for fireplaces, stoves, boilers and furnaces.

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.
