Thanks, Ratman

Hi Alicydon, thanks for your very helpful views with ref the top ceiling rail etc ...I have no tiles on the ceiling and the rail both sides of the twin wall pipe is a non combustible stone material.The oak looking mantlepiece is also made of stone.I have no skirting behind woodburner either.The only items that do not belong are the birthday cards which you are spot on and have been taken down.Carbon monoxide is below the rail on opposite wall just over 8ft away (picture below) I purchased the Dru from a store/ dealer who has now shut down I'm afraid.

Thanks Steven and Ratman for your helpful ideas I will try and let you all know my findings....

Hi Neil,Yes I sweep the flue regularly..I wipe the black pipe down with a damp cloth only,no chemicals to get rid of dust.I built the hearth and installed the fire board and then tiled it to all the correct measurement and then had a Heta fitter install the pipe and sign off all the work for home insurance reason etc...The fitter extended the outside pipe to try and help and I even changed my woodburner after the fitter suggested it could be that it was a poorly made one. And we've also tried a rotating cowl cover but this problem still remains:(

Hi Ratman.No, that does not sound daft....at this point I will try anything.Will certainly give it a go...I do have some very nice dry logs that I could try in the meantime without the smokeless coal I have been using...Thanks for your suggestion!

Thanks Phil and Dumper,I do have that exact thermometer but was just discussing with the wife about getting an Etekcity Lasergrip 1080 Non-contact Digital Laser IR Infrared Thermometer, -50°C ~ 550°C ( -58°F~1022°F ), Instant Read Temperature Gun..Other temp guns available:) Yes Phil,Black pipe is 5" and the insulated one is 6" inside which I was wondering would this be having any effect which goes straight up with no more bends above the roof....Fire is running at the moment at 290 ish which is just in the black with no smell...I know it should be in the grey and that's why I'm thinking of getting the temp gun to check the accuracy of the pipe temperature..I positioned the existing thermometer 18" above the stove on the pipe. JUST stood up to make a cuppa and can just start to smell it again...This is after several hours of running it this morning:(((

Hi,I do have a damper on the box itself at the bottom below the coal line and with it being a multi fuel wood/caol burner it also has an air intake above the glass window to allow for burning of wood which is kept closed when I burn smokeless coal....My one question that I can't seem to get an answer to is whether I should change the 5" pipe which extends into a 6" pipe about 6ft after it comes out of the woodburner? It's designed for a 5" initially and max output is 7kw. Thanks for getting in touch:)

It's hard to describe the smell..I guess it is like a very hot metal smell.I clean it regularly as well.I used to have a bigger stove 11kw (which had the same problem with the same smell) which I installed a vent for but this one is a 7kw.It's designed for a 5" pipe but as I mentioned it goes from 5" to a 6" pipe after a 6ft or so and I wondered if that might be creating the problem? One last thing I'm burning 80% smokeless coal with just a bit of starter wood,stick:) Thanks for your reply

Hi,I have a Dru44 Multifuel woodburner and wondered if anybody could help me with a problem I've had for years...I have even changed my woodburner but still the problem persists.Fire starts with no problems but once hot it starts to smell not smoke or backdraft etc....I then have to open the fire door and let it cool down a bit as closing the air intake takes far too long.. wondered if I should change all the pipe to 6"? The Dru is designed for a 5" which is what I have coming out the top but then it changes to 6" double walled after about 6ft which carries on to the roof. Thank you
