Harmon MKII Backdrafting

Modern and vintage hand fired coal stove are similar to a wood stove and in some cases can burn either. They need to be regulated and fed by hand usually every 12 to 24 hours depending on your usage. They require no power to operate making them ideal for rural settings with long power outages.

I would agree that you do NOT want a 6" chimney...
The flue area should be greater than the stove outlet.
Some stoves have a 5" outlet.. that doesn't mean
you'd want a 5" flue.
I believe Harman recommends at least an 8X8 liner.
Even an 8" rnd would be less...
That isn't to say an 8" won't work. But it is small..
But a 6, is just way undersized..

Thank God for the moon...
It gives us light at night, when we need it.
Not like the sun that gives us light in the daytime,
when we don't need it.
