Okay I've had my lovely stove for getting on for a year now and I really want to fix the pipe/plate seal good and proper. Fed up with vermiculite seepage!!
So what have people done that's a succesful long term fix? I've heard of a special tape (what is this called) and high temp silicone - though black is hard to source for a decent price. The gap is ~4mm
Solutions & links please
Cheers, Mike W
