Breaking Out Flue

[lawn717]

I’d like to break out the flue liner going to my basement and install a 6” insulated liner for a wood stove.

Renting a tile breaker from Rockford seems expensive, are there other routes/suggestions?

Clay flue is 8x13 and a straight shot to my basement. The chimney is a little over 20 feet. Home built in late 1940s.

Shouldn't a 6" liner fit down that without breaking it out?

Good question. 8x13 is OD. The ID is just a hair over 7”. Once the 6” pipe is insulated, that’ll leave little if any wiggle room.

Nope not a chance with insulation

You can just use an oval liner

Right, I did that for the other flue I have going to the Drolet insert in my living room. I ruled that out an oval liner, but don't see any reason not to if it saves me from breaking out the clay flue?

The only reason would be if the existing flue is extremely dirty and it would be easier to just break out than to clean

In that case I definitely don’t have a reason. It’s dirty but cleaning it IMO would be much easier than breaking it out.
