Installing a radiator on to existing circuit

Just checking: I have installed a new radiator about 2 meters away from my radiator circuit. I have tapped in to both the 'out and return' pipes and connected them to each end of the radiator. Is this right or should both ends of the radiator be connected to the same pipe? does it matter what way around the water flows through the radiator?

Cheers for any advice

Sounds right, and

it doesn't matter, but put any thermostatic valve on the flow end. Though they're suppose to be OK either end.
