I have converted my concrete block with asbestos roof construction garage to a workshop with patio doors and now want to fit a small log burner.
My question is can I run the flue 1.8mtr up from the stove and use a 90 degree bend to go through the wall and have the pipe end just proud of the outside wall? The reason being I don't want to cut the roofing material.
Any advise would be appreciated
If you are thinking of an 1.8m rise inside the garage and the outlet protruding horizontally outside the wall without any external vertical flue, the answer is an unequivocal 'no'. Apart from safety considerations, you simply won't get enough updraught to run the stove properly. You will need an insulated vertical external flue at least 3m long.
As W2S said, HETAS guidelines are available online - eg
here.
Well worth a read.
You don't need to have a HETAS engineer do the installation, but if you want to comply with building regs and insurance requirements you need to get one in to sign it off - they fix a riveted plate on the work certifying conformity.
I suppose most of us with home workshops take risks from time to time, but in my case I sort of creep up on danger - whoops, that was a bit scary, not going there again. You might not get that option with carbon monoxide poisoning or fire though.
Obviously I have been down this route myself - I ended up taking professional advice.
