My chimney won't budge. I have no doubt this is at least in part due to going under a low bridge a few months back, must have been asleep at the tiller or something, but it was high enough for the chimney proper to fit, but just too low for the rain cap, which bent backwards. I was able to get it back in place, just a little battered looking.
But I think the chimney also got bent out of shape a bit, not very visible, but I don't think it sits as straight on the collar as it did.
Any tips and warnings? I've heard about wrapping some rope round it about halfway up, twisting the tension with a spanner, in the hope the bottom flares a bit, making it easier, but that didn't work so far.
I assume a few squirt of silicon lubricant are a good idea. I won't be using the fire for a few days minimum, so I should have thought that's safe enough, but does anyone disagree, or want to make other suggestions?
Thanks!
