[Stoves] Pyrolysing side draft stove, 1982

[Alex English]

Crispin,

I helped install one of these in a big brick house in eastern Ontario 
back in the early winter of 81-82. It seemed to have all the answers but 
for a variety of reasons, not all of them were the stoves fault ( not 
unlike cooking stoves), it was a disaster. It ended up in court, the 
Jetstream was removed.
