About Posting a Comment

Comments are moderated before they will appear on the website, this is a manual process and may take some time. Please be patient.

Author Name is a required field.

Email Address is optional, but without one I won't be able to contact you back. It is never shown or linked on the website. You can always just email me if you'd rather not post a public comment. I generally reply in-line with a comment rather than email you back, unless I want to discuss something in private or off topic. Please check back to see when I reply.

Website URL is optional, if supplied the Author Name will be hyperlinked to this URL.

You may use wikitext in the body, preview may be handy here. Don't worry if you can't figure them out, just give me a hint what you want linked to what and I'll do it during moderation. Wikitext is not BBcode!

Spammers: Please don't bother wasting your time scripting up posts to this form. Everything is moderated, your post will never be seen on the web even transiently, there is no way to even view it by its internal ID, it will never be indexed. I will simply delete your post in the moderation interface. If I'm your target audience you're really on the wrong track; I'll never click on a URL in your garbage. The post content is not emailed to me (and I don't use a Win32 mail client anyway), I view the posts in plain text in the moderation interface so no clever tricks of any kind will make anything you type be interpreted by anything other than me, a human. Just give up and go elsewhere please!

Thanks for your concern, but the danger of fumes from the galvanised metal is essentially zero. Not only do the walls not really get hot enough to start burning the zinc, but the dangers of metal fume fever are in general enormously exaggerated, especially for Zinc.

I've personally been exposed to very large amounts of Zinc Oxide smoke and never experienced any ill effects. Other metals are plausibly toxic, but Zinc causes only a minor immune response in *some* individuals.

You should not be using the furnace indoors, so inhalation of significant amounts of fumes would be unlikely anyway. The Carbon Monoxide released from the burner is a much more acute danger to your body than any metal fumes from the furnace hardware. The charge of course might be a different matter.

Using Galvanized metal for teh furnace is a no-no since when heated the ganvanizing burns and gives off a poisionus gas.
