What would you do if the gas valve is not closing after temp is satisfied?

I have a L8148J (24Vac) on my boiler connecting to 2 zones with Honeywell 8043E valves. There are 4 conductors in the thermostat wire. Which terminal in the aquastat can be used for "C" wire to Nest thermostat? Thanks.

Does this L8148J has enough transformer power for a vent damper?

I do have three questions:
1) Where the red jumper is, it is for a 24V thermostat ..??
2) Where the yellow jumper is. It is to connect a millivolt thermostat?
When is necessary to remove the jumper between Z and W ??
