Hi, I have recently bought an oceanis 31 which came with a furling gennaker
but with no fitting instructions! We have managed to attach the furling drum at the bow and hoisted it up but not sure what lines we need and where to make it work. It came with this (see photo) which I think attaches to a clip at the stern ? All help/pictures gratefully appreciated!
 
If you have say a Karver furler or equivalent by say Selden the lines should be attached to drum so once it’s hauled up on spiny halliard and is a sausage from bow to masthead the lines should be goes back to cockpit where you have a turning block. I assume the sail has sheets fitted in the bag which in came with but if not you need to attach these like any headsail -normally they use snap shackles to clip on the sheets for quick release. Attaching a picture on this site always needs a reduction when you attach image then once selected tap show selected to reduce size to say medium -I have attached a picture of our bowsprit from which our crusing chute flies for interest but you might need a selden pole to project the tack of the chute forward of bow but this rather depends on bow design etc

There are two two types of furler, drum and continuous line.
I suspect that you have a continuous line unit.
Both systems need some sort of swivel between the Halyard and the head of the sail. This needs to be free running under load.
The continuous furling line wheel needs to be well forward of the forestay, and the halyard exit from the mast should be above the forestay attachment point.
You need a continuous line of the correct size to match the grove in the wheel, and it's better if the line has soft braid cover to give good grip on the wheel.
I prefer to have the continuous line loop long enough to go back to the cockpit. It also helps to have a snatch block, or a block captive in the loop. The block needs to be attached to a strong point, to give a good lead to haul the furling line.
The continuous line may need guides to run it down the side deck, these are often fitted to stanchion bases.
I've made lots of assumptions here, to get some discussion going.
Some photos of the setup on the boat would really help in giving more focused advice.
