the key to getting around this for me was to install the chimney before you put tension on the pegs around the bottom of the tent, this means that the webbing straps at the top of the tent are able to be parted by the heat-shield without too much stress!
Interesting, that might well also help for sure. Think I'll now need to dust off the stove which I haven't used for a few months and have another play in the garden this w/e!! Thanks
