Just installed a stainless chimney liner for a wood burning stove.
Register plate not yet in position. Bottom 3 meters of the liner is
insulated with rockwool sleeves.

The first three fires I've had have been progressively hotter, each
time I get masses of smoke come down the chimney into the room. It's
not wood smoke, it has an acrid chemical smell.

Is this normal for a new liner, do we just have to ride it out?

Cheers

Nick.
