Tado Smart heating wiring

Hi All,
I got the below tado home smart heating kit on screwfix
I'm replacing an old fashioned Flash immermat 31100. Beside this are 2 switches for 2 zones (upstairs and downstairs) that are never used. (always heat upstairs rooms and downstairs together anyway) (one motor valve is even broken and set to always open with the manual slider on it)We've an 18 year old standard oil burner, it heats the water in the immersion tank when its on but theres no zone for this, if that makes sense.
The old Flash immermat was wired the following 1-4
1 Brown live in (and a brown live going to the pump switch)
2 Blue neutral in (and another grey wire)
3 Blue neutral out ( to boiler)
4 Brown live out ( to boiler)
What way do I connect these to the new tado reviever?
I've put Live in and pump switch to L as before,
and the neutral in and grey to N as before
Where do I put the live and nuetral out for the boiler?
Do I need to use the purple bridge for live to com?
I tried a few combos, and the reviever turns on and connects but when the heating light comes on the burner doesnt fire up.
I've a friend calling tomorrow whos an electrician but he deosn't do much work on homes so if anyone had any answers it might help him out if he can't figure it out.

I have the wifi bridge and wireless thermostat connected, and power to the wireless heating reviever.
