Fixing distances are the same regardless of what the pipework is being fixed to.
Pipework should be insulated and any brackets/clips etc should also be insulated.

Don't tie wrap the pipe to the tray in the riser, as the pipe could slip inside the insulation and cause a probelm with the vapour seal. If you pull the tie to tight it will cause a failure of the insulations integrity.
Best to clip with Insualted HYDRO-ZORBS or CUSH-CLAMPS on channel.
