I have bought an Econoburn 100 BTU indoor gasification boiler. I've decided to replace one of my aging triple-wall, air-insulated chimneys with a new double-wall, solid-pack insulated all stainless steel factory-built chimney. I was all set with Simpson Duratech when I was reading the installation instructions, which say "Do not use with forced draft, positive-pressure appliances."
All of the Duravent products carry this warning. I found something similar with Selkirk Superpro.
So I called Econoburn and the CSR said he has a Duratech chimney at home (attached to his Econoburn boiler). He said that factory-built chimneys must be UL 103 HT, and that he's seen a lot of Duratech chimneys attached to Econoburn boilers.
Are factory-built chimneys incompatible with gasification boilers, or is this just the chimney people making sure they don't get sued?
