Hi again, After typing in a lot of information, the page disappeared. Is there a time limit to adding a reply? As promised, here is more information on the distribution of hot air from a wood insert. Go to www.flamme-bleue.com and go to page 2 les inserts,la distribution d'air chaud. There are diagrams and explanations. If you can get a catalogue from deville or Richard le Droff the same information is in them. As I said before, all the parts are available in the bricomarches.
