Can anyone help me please?
I have some old clay pipes I was going to use for my flue, but I'me not sure they will be long enough, so I have decided to use 6" flue pipe instead.
1, Can I use single wall pipe, or should I invest twin wall pipe?
2, How do I fix it to my stove? Can I just wedge it between bricks and mortar it in? Or do I need a fixing plate?

Twin wall is considered to be the most effective, single lengths can be had for little money on eBay or put an add on Freecycle. Most systems will have an anchor plate if you can find one,but if it's a permanent fixture then mortaring it in will work just as well.

I did think of mortaring it in, then questioned if I needed something to hold it in place and keep it stable. |

I had the same thoughts with my flue having seen a post from another member say that having cemented the anchor plate, when fitting the flue, the mortar cracked. A few posts down on my build here >>> ukwoodfiredovenforum.proboards.com/thread/2262/berkshire-corner-pompeii-first-build?page=5 you can see having shaped the bricks to fit in the entry arch, I drilled out space to bolt the anchor plate to the top of the arch, bolted, then filled the holes with fireproof silicone (although I don't expect this to last as only good to 300/350c). Since those pics I have also put an inch thick firebrick top over the anchor plate. Have fitted and moved the chimney a dozen times now, and fixing is solid. |

Yes indeed, as used on wood burning stove/oven installation.
