I am installing a log stove in my new build under building regs, and am having a bit of a problem getting the stove pipe the right length to fit. We had a pumice flue installed which terminates in a register plate. The register plate has a male pipe end which the enamelled stove pipe slips over preventing creosote from dripping out. The bottom of the stove pipe slips into the stove.
I bought a 1m stove pipe but its 25cm too long, and the only way I can see this fitting is to cut the bottom off and buy something called a "cut length adaptor" to replace the fitting at the bottom of the pipe which I cut of to get the pipe the right size.
