I discovered that this posting from 6 September 2010 had somehow been used to create a link to a porn site. Bloody cheek! And I'm not into, nor writing, a porn blog, and have absolutely no desire to facilitate such an activity. So, I have deleted that blog posting, and am reposting it here, under a different heading.
So here it is. My apologies, the picture isn't that clear but I hope it gives information to whoever needs it. I always like as much information as I can find - helps me operate an item to its’ full capability.
(nos. 48 and 49 don't apply - but everything else does.) Happy Cooking :-)
Update: I have given the basic instructions on how to operate a Dover stove here.
As I deleted the original posting, I decided that I would also repost the comments and replies as there is some information there which may be iof interest / assistance to future information seekers :)
