DIY wood burner installation and building regs

Firstly, apologies if this has been asked a thousand times but.....
At long last i'm able to afford to install a burner. Currently we have a open fireplace with an opening that's around 2' wide, raised 5" off the floor level and the same 2' in height. I'm looking at either a Morso squirrel 1410 or an Aarow acorn 5 based on the 'room calculators' recommending a fire with around 4/5kw output (although it seems a bit small for me, our lounge measures 4m wide by 5m long by 2.5m high approx). I know i will have to alter the actual fireplace and put a new hearth in but it's the flue i obviously need to get dead right. When we moved in there was an electric fire (looky like woodburner job) which we got shot of. There was a register plate already up there which i let the local scrapman have as i thought i'd never need it (doh!) so i need a new one. The chimney virtually rises to the top with a small kink about 3' up and then it's dead straight. Obviously i need an installation kit plus a 10m length of liner but i can't understand this talk of 2k flue liners? What am i missing. Is it the backfilling with vermiculite or is that not necessary? I can get HETAS certified liner at £21 m plus VAT so is that 2k figure for double skinned liners/flue in un-chimnied installs? Anyhow, the Squirrel has a 5" flue and am i correct in thinking i need 6" liner or did i read that wrong?
So, i alter fireplace to allow correct clearances to the side, back, top and bottom of burner with correct hearth clearances. 600mm of vertical flue from burner into register plate with 5 or 6" liner pipe clamped on and then rise to top of chimney. Fix to closing plate and clamp and use hangers to attach to existing pot (not sure that's right) and fix cowl. I know it all needs to be gas tight and it needs to be signed off. Do i (of course i know i do but..) need to pay for said inspector to sign it off, how much if so and do i contact him via Borough Council? There's probably loads i've missed here and any corrections, advice or ridicule is welcome, i just need to get it right. BTW my brother who is a builder is lending a hand (in return for Sunday Lunches) which should save considerably on costs.

Hokay.. Morso is a good choice of stove. I fitted my own stove and had the install signed off by building control £65 fee i think. Fees vary from council to council. I would recommend fitting a minimum of a six inch liner (good installers wood not fit a 5 inch liner). Buy a good quality liner 904 grade will be the best in the long run. Not all liners are constructed in the same way and could come apart when you try to thread it through your flue. You can use a pot hanger or remove a the pot and secure with closure plate and clamp whichever you prefer. Register plate can be sourced from you local sheet metal worker who will sheer it to size for you. Mine was £5 for a galvanised 2mm piece, the offcut which I sold on evil bay for £5 so was in fact free! Frame for register plate made from angle iron bought from steel stockist for £12 a length. Surplus sold on Evilbay for £5. Vermiculite was £8 a bag from Travis Perkins. Insulation a good idea as it will "support" the liner when sweeping as well as help to keep flue temperature high and help to prevent tar & creosote deposits forming if timber is not well dried to some extent. It took 3 Bags for my flue 9 inch X 9 inch flue approx - 6 metre length. CO alarm from Ebay. Notice plate required too.
Liner from here: http://www.ncc-flue.co.uk/main.asp?shopid=1 Other parts from various suppliers as I do like a bargain.

Good luck. Phew ...sorry in a hurry tonight!If at first you don't succeed, skydiving is not for you! :dance:0 -
Okay, so i'm settled on the Morso which comes in at 388mm wide. My fireplace opening is 540mm leaving a surplus of 75mm each side. Unless i'm willing to widen the fireplace (which ideally i'm not) am i wasting my time unless i drastically alter the fireplace opening? Would it damage the stove having that clearance to the side? Ta muchly!0
