Draw a box 2m below and 600 either side if it's in that box it's a no go
Thanks for that.
In the Vokera Manual I can see the 600mm measurement if to side of a Velux and the 2000mm measurement if below but no indication of the relevant measurement when the flue is not directly to the side nor directly below. It makes sense however to have a measurement for that scenario - I was relying on Vokera Technical who said,
"Yes, that would be fine. As long as the 300mm clearance to the slate is maintained and it is at least 300mm from the velux window ."
Do you happen to have a source to the diagram you describe please?
I'll draw Vokera Technical's attention to your post to see if they have a comment.
Thanks again.
