It does not depend on the diameter, it does depend on the class of liner. Class one is for solid fuel and class 2 is for class 2 gas (1 has a natural draw the other does not). The older open gas grates used a class one 180mm or 200mm id liner and the class 2 liners were/are mainly 125 or 100mm (occasionally 150mm). Class one is 316 grade and double skinned with w 10 year warranty (you could also use 904 grade with a woodburner which has a 20 year gaurantee). Gas class 2 is single skinned and will burn out straight away if used on solid fuel.
A hetas registered person should install or you could get a builder to do this and have the work signed off by buildiung regs however the liner should be data plated and the stove certificated. You will also need a CO alarm to room.
