tell you what looks iffy to me thats a standard efficiency performa with what appears to be a high efficiency plume kitI had to ring Heat Team about this as I had never come across something like this before. They confirmed that you can have a maximum of 5 meters drop on the flue, taking off a meter per elbow. So this is actually ok. But my god does it look dodgy!
This might be ok, I didn't actually go to this property I just noticed it on my travels and took a pic.
