No I should've tho.. looked great. I had a window open, & door alot too, but I did think of your advice. Will buy before next fire. Tbh it's impossible to use unless flippin cold I think.. so could be October next time. Main things ticked tho: draw seemed good, stove paint smoke ( assumed so) subsided... & main thing: it'll be mighty economical!! Woohoo! Makes a total mockery of my main s'room one already. So I can run this entirely from forraged wood from lanes/ spots all around. No doubt at all.

I think I'll get used to it/ not notice tbh. Could be a very- last on the list jib tho. After the whippet. And Wilbur is waaay down still. Did just fire her up tho! Thx zoot.

Just fired her up! Omg there was all sorts of smoke nasties coming from the stove, but I saw from general 'all over' areas not vent areas.. & subsided after a fretful 3/4hr. I think. Blazingly sauna- hot. Wow. I only did a small fire as Peter suggested too. This thing is mighty capable, fab design. But have I got twice what I need? Hmm.. seems so to me. 2 other concerns: the twinwall gets almost as hot as the single, you can barely put a hand in more than a second; now I did the fire test of a knauff fluff offcut ( stuff I ID'd a few posts before).. & wouldn't catch/ impressive. Lastly the fireboard directly behind/ nearest stove gets mighty hot just from my small fire. I checked outside @ this exact spot, hand on wall, & cold as can be. I am therefore putting alot of trust this muuri paint + cement board. Quite a 2 hours! Much guinness needed, for strength. Zoot.

Hi Peter- that's one thing I forgot then. But I guess it's too late now having set for a week, so when I fire up 1st will be same now as if I wait-? 1/2 a cut up 450mm pave slab each side, & ceiling plate nipped to shape around trickier LHS of flue. A bit 'zincy' but cheap & you don't look at it.

I will do when a cold snap comes ProDave.. I'll roast in there now. If we had 26*C in feb last year, we might get 5*C in june.

Last bits done/ job fully complete. I'll add an update once fired up, maybe september or so.. but hugely grateful to all for the help ( & patience with my Q's!). Zoothorn.

I do, but wasting 3/4 of a board, @ £15.. So I'm going to try the Muuri painted tiles 1st. Monitor. I think Im far enough from flue at 8", top area. If they get super hot.. I can remove & redo. Looking forward to firing her up! Hoping for a silly cold snap. Thanks, zoot.

Paint 10" sq (8mm D) ceramic tiles 2x in Muuri paint... then gun adhesive/ stick to walls here? Pic again. Also could do same around stove, to broaden the fireboard width by 10". Pic again..

I am certainly taking great advice.. no doubt there: followed Peter's steps to a T & I was on a sure footing. Thanks. Good that's sorted then. Wait for plate/ flue done. Checked in rain last ev & all's well. Really pleased too. ---- Very last Q if I can chaps. As you can see on page before, I was an eejet measuring & fell short with my fireboard. So top of enamel flue is unprotected by 9" H. Now thankfully the black flue is a good 8" away from both side cabin walls here. Would I be ok to just paint the walls say 3x in Muuri paint? Or should I wait & add 10" H more cement board? When an offcut comes along.. Annoying. Thanks, zoot.

Good idea.. will do a test. Sand eh? Interesting. Am I stuffing it right up to fill the whole rubber johnny? Or just a band around the ceiling section removed. Thanks. Zh

Hmm.. seems good to go then, but no rush if waiting on my plate thing. So will see if Peter &/or ProDave concur maybe 1st. Thanks Onoff, zoot.

Anyone know if this particular loft roll is ok to go in my ceiling gap? Say it's non-combustible.. https://insulation4less.co.uk/products/knauf-combi-cut zh

Hi SAS. That sounds like the one Ive gone for.. as long as there's a bit of give.. should be ok. Cheers, zoot.

Hi Onoff. No unfortunately I don't have or I'd use it to heighten the boards' area up to the black flue top bit. I measured wrongly in fact for the 4 sections of board I cut & used from 1 sheet, hence the odd sized bits & not high enough. Mistake. Ive gone for my ebay one. I just mocked up two 158mm W halves in cardboard, as the seller shows its W to be. & with a bit of bending- should do. Just need to find some rockwool bits. I do have some knauff insulation roll, the beige stuff ( in a white/ blue big roll). Would this be similarly fire resistant? Thanks, zoot

@ProDave I wonder whether I could fettle this to play ball.. https://www.ebay.co.uk/itm/293358505044?hash=item444d878c54:g:9k0AAOSwfVpYq-vP

Aha great thanks, understood. I forgot rockwool was non flammable. I do have my 1" of ecotherm board sandwiched between my roof layers. A bit late in the day, but this is no issue.. is it? Grateful, zoot

Hi ProDave, useful link thanks. Did see these things. Thing is as it's on a slope, this won't fit too well I'd have thought? Its that pesky oval shape etc. What about something in the 1" gap around twinwall, actually in the ceiling? Thanks, zoot

I've got a few things to address before firing up. 1. is sealing around fireboard gaps/ joins, got some NN'sense fire tube stuff. 2. Im a bit short on the fireboard, so need something to add top of enamel flue -ideally an offcut cement board bit, if I can find. 3. I have wedges in my ceiling oval at the mo, I was going to add L shape brackets, under the johnny, 3 to secure flue solidly but was in a rush. So maybe add say two inside @ pic 2? 4. some plate thing to cover over the ceiling oval cutout, not so easy being an oval shape. 5. Lastly: something actually in the ceiling gap.. Ive seen some folks stuff rockwool here. Need to find offcut/ can do this job & 4 in time. No rush, warm weather on it's way. Thanks, zh

Job.. done! Woohoo! Started raining of course soon as I cut me hole.. & (new) gun whatnot broke when I went to stick my johnny down. But rain stopped, dried up.. & fab results. This, I think, is the most satisfying build job so far. 4 hours flat out 'blitzed' it. It warrants a zoot musical interlude, before pics tomorrow. Thanks so much. Zooter.

Good tip that. Will do. Finally looking fwd to the job now.. dreading it just 2 days ago. So important all this prep you see, for me. Thx zoot.

Appreciated. Super silly prep i know.. but important job to have every facet ready, job understood & a plan in place. I think Im set. Just a good weather window & can crack on. My stove guy replied at last, said tho my 'spiggot' male end seems long, using plenty of cement smeared around it should be fine w'out cutting a bit off. Good. All weather silicone to buy, use my screws ^ then galv spray the heads (? my idea) then a layer of this sealant ontop of them too. Putting some also on the jonny-flue join too. Thanks- Zoot Doing a mock

Peter forgive me a newbie's question.. are these screws suitable, to fix the outer alu flange of the johnny down thru felt/ into my osb roof? Or do I need something 'special' ? https://www.screwfix.com/p/easydrive-flange-head-flange-self-tapping-screws-8ga-x-100-pack/6553h Thanks, zoot.

Hi Onoff no Im far from attempting this flue job yet.. as I still cannot understand the correct joining of these 4 pieces. Thanks for link though/ will get in due course. Zoot.
