Do you find that the spindle on the hosereel comes undone a bit when running hot,it seems to work it`s way lose a bit after a fair bit of use.Also it was a bit windy today and i found the flame blew out a few times,there is air vents at the side of the unit that let air in and cause this.The thing is could i cover these vents over to stop it or do they need to be there,by looking at it if these were covered slightly it would stop it blowing out.
