Sadly, the previous owner had lockshields on both sides.
I tried putting on the heating but this rad must be on a spur since both pipes remain cold, even when all others are hot. I guess I will be able to tell when the rad is fitted, but its a nice one and I don't want to put the brackets on the wrong side.
Are you fitting TRV's ? some TRV's instructions state which way they should be fitted. But you can buy TRV's that can be fitted to either side of the radiator.
Does the instructions say why you need to know which is the flow and return ? A normal radiator or towel it doesn't matter.
If the radiator is not fitted, then the tails will not heat up.
Fit the radiator, if it's the wrong way round, all you have to do is swap the rad valves round - I think the instructions will just be referring to the TRV's, nothing to do with the radiator itself.
Maybe its because its a column radiator. The instructions say:
[b]PLEASE NOTE: WHEN CONNECTING THE PIPEWORK TO THE RADIATOR, [/b]THE WATER[b][u] MUST[/u][/b] ENTER THE RADIATOR AT THE BOTTOM CORNER [u][b]DIAGONALLY OPPOSITE[/b][/u] THE AIR VENT, AND[b][u] EXIT[/u][/b] AT THE BOTTOM CORNER[u] [b]BELOW[/b] [/u]THE AIR VENT[/quote]
