Agreed Selkirk’s web site is confusing. The SuperVent is for the Big Box/DIY market and the Ultra-Temp Platinum is the contractor/installer version. They also had specifications that differed on the boxed item, the web site and a pamphlet! We went to the source and cleared it up but it underscores the fact you should always verify your information from several sources before committing to a project. My previous post has a link to a PDF which has the phone number to Selkirk technical support.
The Metalbestos chimney that went up in ’79 was actually taken down in 2000 for a remodel. The tongue/male part of the connection had begun to rot but the inner pipe was still fine. The pipe was maintained properly, was used regularly, had wood and coal burned in it, and had served its purpose for 21 years.
Masonry chimney properly built and located is almost always the best choice. The metal chimney, under certain circumstances, is sometimes the better choice.
You could BRICKMASTER it.
A smooth stucco finish would be ok and you could color it as you wish. Most stucco finishes on chimneys here are white, some with a black trim ring to identify if you were Tory or Whig.http://www.victorianweb.org/history/Whig.html
The liner issue is really due to moisture and a lack of ‘excess heat’ to carry it all up and out of a masonry chimney due to the higher efficiencies of ’modern’ appliances. The liner contains the moisture and minimal excess heat. The moisture condenses when it gets colder and makes a nice corrosive mist/dew inside the chimney.
