Nest power connector with a zone valve

How do I connect the power connector to the Honeywell zone valve.  My Nest power connector has a jumper connector in it. Your literature does not address keeping it or removing it.  If I connect the power connector as YouTube  explains (no jumper in the year old video (keeping the jumper in place) the thermostat calls for heat but does not power the zone valve.  
 One other website suggests removing the jumper and connecting the load side of the transformer to both the thermostat and the boiler relay.

 

can you help?  

A wiring schematic would be appreciated 

 

Thank you

 

Joe
