Stuck wiring glow worm ultimate 70ff boiler?

I have a glow worm ultimate boiler and my system is a Danfoss heatplan pack with programmer and (2 x 2 port valves) the heatplan wiring looks straight forward, but confused with boiler looks like the boiler needs L,N,E + single pump supply wire, also mentions a permanent live to boiler but looking at it i think not required??? the confusing part is the 9-SL connections in the boiler it says take out the red link, what connects if anything to them??? or do i put the link in??
any help would be great
